1 General Information
1.3 Important Cautions
For your protection while using the Razor Side Mount System, we call your attention to the following:
1. Use the equipment according to the instructions contained in this manual and only after having completely
read and understood all instructions and warnings.
2. Use of the equipment is limited to the uses described in this manual or for applications approved in writing
by Go Side Mount.
3. Cylinders must only be filled with atmospheric compressed air, according to the EN 12021 norm. Should
moisture be present in the cylinder, beside causing corrosion of the cylinder, it may cause freezing and sub-
sequent malfunction of the regulator during dives carried out in low temperature conditions (lower than
10°C (50°F)). Cylinders must be transported according to local rules provided for the transport of dangerous
goods. Cylinder use is subjected to the laws regulating the use of gases and compressed air.
4. Equipment must be serviced by qualified personnel at the prescribed intervals. Repairs and maintenance
must be carried out by an Authorized RAZOR Dealer service facility and with the exclusive use of original
RAZOR spare parts.
5. Should the equipment be serviced or repaired without complying with procedures approved by Go Side
Mount or by untrained personnel or not certified by Go Side Mount, or should it be used in ways and for
purposes other than specifically designated, liability for the correct and safe function of the equipment
transfers to the owner/user.
6. The content of this manual is based upon the latest information available at the time of going to print. Go
Side Mount reserves the right to make changes at any time.
7. All dives must be planned and carried out so that at the end of the dive the diver will still have a reasonable
reserve of air for emergency use. The suggested amount is usually 50 bars (725 psi).
Go Side Mount refuses all responsibility for damages caused by non-compliance with the instructions contained
in this manual. These instructions do not extend the warranty or the responsibilities stated by Go Side Mount
terms of sales and delivery.
WARNING
Always perform a pre-dive and post-dive inspection of the Razor Side Mount System.
WARNING
Do not use your Razor Side Mount System as an assist or “lift bag” for bringing objects to the
surface. These objects may be lost during the ascent, creating a sudden increase in buoyancy
and loss of buoyancy control.
WARNING
Do not attach a LPI hose to a scuba regulator high pressure (HP) port or to an air supply with
pressure in excess of 200 psi (13.8 bar). This may result in damage or explosive failure of the
inflation valve or low pressure hose, which could result in injury or death.

1 General Information
1.4 Inspection and handling of the BAT Wing
Pre-dive, dive and post-dive BAT wing examination helps to identify equipment problems before unsafe condi-
tions exist, preventing diving accidents. All equipment must be regularly inspected by an authorized SCUBA
equipment repair facility.
Pre-Dive Visual Inspection and Valve Test:
1. Examine the entire Razor Side Mount System for cuts, punctures, frayed seams, excessive abrasion, loose /
missing hardware and other damage of any kind.
2. Inspect the Oral Valve, Power Inflation Valve, Manual Dump Valve and Over Pressure Valve(s) for cracks,
damage, or contamination.
3. Operate the Power Inflation Valve (with the LP hose attached and charged with air pressure), Oral Valve,
manual Dump Valve and Over Pressure Valve, checking for proper operation and resealing. If the OP Valve
has a Pull Dump, test it by pulling on the cord.
4. Inflate the BAT Wing through the Oral Valve until it is firm. Listen and check for leaks. Let the BAT Wing stand
inflated for 30 minutes or more, then check the BAT Wing for loss of air.
5. Cross check all valves’ operation and visually inspect your Razor Side Mount System with your dive partner
before each dive, prior to entering the water.
WARNING
DO NOT DIVE with a BAT Wing that does not pass any of the Pre-Dive, Dive or Post-Dive inspec-
tion points and tests. Loss of buoyancy control or air holding integrity could occur, resulting in
serious injury or death.
WARNING
DO NOT DIVE with a BAT Wing that is damaged, leaks air, or does not function properly.
Terminate any dive as safely and quickly as possible if the BAT Wing becomes damaged, leaks
air, or does not function properly.
WARNING
The BAT Wing is not a breathing device. Never breathe from the BAT Wing. Your BAT Wing may
contain gas residue, liquid, or contamination that may result in injury or death if inhaled.
WARNING
Keep water out of the inflatable aircell of the BC. Repeated use of the oral valve or the
Overpressure Valve may allow water inside the BAT Wing, reducing the amount of buoyancy
provided by the BAT Wing. This could result in injury or death. Drain all water out of the BAT
Wing prior to every use.

completely if storing, slightly inflated.
1.5 Inspection and handling of the Razor Side Mount System
1 General Information
WARNING
Avoid prolonged or repeated exposure to chlorinated water, such as in swimming pools. Wash
your Razor Side Mount System immediately after any use in chlorinated water. Chlorinated
water can oxidize fabrics and materials on your BC, thereby shortening their life, and cause col-
ors (especially neon) to fade. Damage and fading from prolonged exposure to chlorinated water
is specifically not covered under warranty.

«Necessity is the mother of invention»
Steve Bogaerts originally designed the Razor Harness for use on side-mount / no-
mount exploration dives in very restricted cave where every piece of extra equip-
ment can become a hindrance or hazard.
The system evolved over time as the exploration dives became more challenging
and demanded more from both diver and equipment. The current system is the
distillation of years of trial and error. That experience refined and streamlined
equipment, skill sets and procedures.
Each of the components in the system is designed to fit together seamlessly and
work as part of an integrated whole. The Razor Harness is at the heart of this sys-
tem and is the foundation of all the Bogarthian Side-Mount procedures.
To get the full benefit from your Razor Harness you need to understand and imple-
ment the entire Bogarthian Side-Mount Philosophy. This philosophy is holistic in
approach and is designed from the inside out so that as additional layers of equip-
ment are added there is no change in the core equipment, equipment placement,
procedures or skill sets.
Get properly trained for Side Mount diving. Training will distill into a few days’
years of experience and advance your Side Mount diving accordingly.

«Less is More»
The Razor Harness is simplicity and elegance personified with only 2 continuous
pieces of webbing and 1 closure point. It is simple, strong, rugged, reliable, low
profile and extremely minimalist in design. It fits like a glove and is very comfort-
able to wear.
The Razor will fit anyone no matter what their physical size or shape and is quick
and easy to set up and adjust so that each individual diver gets a custom fit using
standardized hardware.
The Razor can be adjusted at several points to ensure the optimal fit for each indi-
vidual.
Each of the Shoulder Straps / Waist Straps can be adjusted at the Mini Back Plate.
The length of the Lumbar / Crotch Strap can be adjusted at the Delta Shoulder
Plate. The height of the Waist / Hip strap can be adjusted at the Mini Back Plate.
All the attachment points such as D Rings on the Razor Harness can be adjusted
quickly and easily to allow personalized positioning of equipment placement.
Extra attachment points can be added easily if required.
Weight can be added to exactly where you need it on the Razor Harness to opti-
mize trim.

W W W . G O S I D E M O U N T . C O M
Below is an easy to follow guide detailing the 10 steps to rigging and adjusting
your Razor Harness.
Each step has supporting pictures.
W W W . G O S I D E M O U N T . C O M
It is highly recommended that you read through the guide and look at the accom-
panying pictures to thoroughly familiarize yourself with the various parts and
assembly procedures before you start to put your Razor Harness together.
W W W . G O S I D E M O U N T . C O M
Ideally you should have your Side-Mount Instructor rig your Razor Harness with
you.
Rigging the harness is much easier with 2 people.
W W W . G O S I D E M O U N T . C O M
No one is perfectly bilaterally symmetrical and a properly fitted harness will not be
either.
The person having the harness fitted should wear it while their partner makes
adjustments in situ to get the perfect fit.
W W W . G O S I D E M O U N T . C O M
If rigging the harness by yourself a full length mirror will help you to position every-
thing correctly.
Ideally when you rig the harness you should do so while wearing your normal expo-
sure protection so that it fits snugly. If that is not practicable then wear clothing
of a similar thickness to your normal exposure protection and make sure you leave
some extra webbing for later adjustments should they be required.
W W W . G O S I D E M O U N T . C O M
It is highly recommended that you use the T weight system with the Razor Harness
however if you are going to put weight directly on the Razor Harness then it is
advisable to work out how much weight you will need and where you want to place
it on your harness before assembling it (see Step 9: Weighting and Trim).
4.2 Overview
Place the Slotted BAT Wing
Tri-glide and the Butt B Ring as
shown next to the lumbar/crotch
strap.
b
Run the webbing through the
lower slot and run the metal
parts in position before running
the webbing through the second
slot of the BAT Wing Tri-glide.

If using a butt mounted primary light canister
remember to leave the crotch strap a little loose
so that it can pass over the light canister to hold it

The loop of webbing created between the DSP and
the Bungee Tri-glide should be large enough to
comfortably pass the Side-Mount Bungee
and clip through with the bottom of the
loop in line with the armpits (see Step

W W W . G O S I D E M O U N T . C O M
To get the right height
place one arm behind your
head and the tips of your

Make sure that the top of the DSP
is clear of your Drysuit neck seal or zipper.

W W W . G O S I D E M O U N T . C O M
Weights can be added to the Waist Straps where they exit the MBP if required
but it is recommended to use the T Weight System rather than add weight
directly to the Razor Harness itself (see Step 9: Weighting and Trim).
All the hardware on both sides of the waist straps will have to be removed in
order to do this.
W W W . G O S I D E M O U N T . C O M

Making sure the DSP remains in the correct position the shoulder D Rings should
be positioned at the same approximate height as the ends of the clavicle.
W W W . G O S I D E M O U N T . C O M
To fine tune this position stand with both arms straight out from the shoulders
palms facing down and thumbs extended then bend at the elbows until the
thumbs hit the shoulders without lowering the arms.
W W W . G O S I D E M O U N T . C O M
The D Rings should be placed at this height and can be moved to the ideal
location easily by sliding the serrated Tri-glides either up or down the webbing
ensuring each side is even in height.

W W W . G O S I D E M O U N T . C O M
The two Drop Attachment Points (DAPs) should be positioned on the waist
webbing either side of the MBP.
W W W . G O S I D E M O U N T . C O M
The DAP’s should be close to the MBP so that anything clipped to them will not
hang too far to the sides and get between the body and the SM tanks.
W W W . G O S I D E M O U N T . C O M
If required the loop of the DAP can be placed in a vice and bent gently to have
them stand off slightly from the body to make clipping in easier.
W W W . G O S I D E M O U N T . C O M
The DAPs are an ideal location to clip off the Razor Expandable Pouch as well
as other items such as reels or lift bags for example.
W W W . G O S I D E M O U N T . C O M
The DAPs can also be used to clip off a heavy butt mounted primary light canis-
ter to give it more support if required.

Now move the serrated belt slides and 2” straight D Rings until they are posi-
tioned just behind the hipbone on each side of the waist strap webbing.
W W W . G O S I D E M O U N T . C O M
Make sure that both D Rings are positioned evenly and far enough back that
the bottom of the Side-Mount Tanks will not hang down below the body when
trimmed out in a horizontal position.
W W W . G O S I D E M O U N T . C O M
Weights can be added to the Waist Strap between the DAPs and the Hip D ring
if required but it is recommended to use the T Weight System rather than add
weight directly to the Razor Harness itself (see Step 9: Weighting and Trim).
Hardware on both sides of the waist straps will have to be removed in order to
do this.
W W W . G O S I D E M O U N T . C O M
Extra attachment hardware such as a second D ring on each side can be added
at this point if required.

Steel tanks will tend to remain negative throughout the dive even as gas is used
from them. However if using Aluminium 80cuft Side-Mount tanks a second attach-
ment point further forward is necessary to adjust tank trim as gas is breathed from
the tanks and they get lighter and become more buoyant.
W W W . G O S I D E M O U N T . C O M
When the bottom of the tanks start to float up clipping them forward keeps them
horizontal along the sides of the divers body thus reducing profile and drag.
W W W . G O S I D E M O U N T . C O M
The first D ring should be positioned behind the hip with the second d ring posi-
tioned half way between this and the center line of the body.
W W W . G O S I D E M O U N T . C O M
The Low Profile D Rings are ideal for use in warm and cold water using either
Aluminium or Steel Side-Mount tanks.

Version 1 is the tuffer but more streamlined one. To be able to make
this work you have to run the webbing on the inside of the Tri-glide.

The loop of webbing between the buckle and the wide gauge Tri-glide should
be small enough so that neither of the buckle plates can rotate and are held in
the correct orientation.
W W W . G O S I D E M O U N T . C O M
The buckle should be positioned to fasten in the middle of the waist and be

When the webbing is new it will
be stiff and somewhat difficult
to use but after a few dives it
will soften and develop a
certain amount of “memory”
that will make it much easier
to work with.
W W W . G O S I D E M O U N T . C O M
If you use soft webbing to
begin with it will get too
soft after a few uses and
the harness will tend not

difficult and it will wear
much faster.

Diving either under weighted or over weighted is inefficient and potentially dangerous.
Correct weighting is critical to mastery of buoyancy control and trim allowing easier more
comfortable diving.
Both the correct amount of ballast weight required and its ideal position on the diver
need to be established.
Enter the water wearing all of your equipment including your normal exposure protec-
tion and full tanks.
Dump all of the air from both the Primary and Backup BAT Wing and your Drysuit if you
are using one.
Add any weight required until you are neutrally buoyant while holding a normal breath
just below the surface.
This is the amount of weight you will need to add to the T Weight System and/or to the
Pocket Weight System plus a small amount extra to compensate for the weight of the
gas in the tanks.
It is recommended to redo the weighting check at the end of the dive with the gas in your
SM tanks at 750psi / 50 Bar.
Now you will need to establish the correct positioning of the weight to improve trim,
swimming efficiency and your stability in the water.
Trim has 2 components horizontal (head to toe) and lateral (side to side).
Horizontal trim can be optimized by moving the weight higher or lower as required.
Lateral trim can be optimized by positioning weights as close to the center line of the
body as possible to minimize turning moments.
Having weights positioned as close as possible to both the center line of the body and the
middle of the body will give greater stability and therefore greater control while diving
in all orientations.

Weights can be added easily to either the Lumbar T Weight Belt or the Waist T
Weight Belt or to both if required.
W W W . G O S I D E M O U N T . C O M
The optimal positioning for ballast weight assuming neutral trim is to either side
of, or just above the MBP using both the Lumbar and Waist strap of the T Weight
System.
W W W . G O S I D E M O U N T . C O M
When using the BAT Wing this ensures that the center of gravity is also the center
of buoyancy thereby increasing stability and control.
W W W . G O S I D E M O U N T . C O M
If more head down trim is required which is often the case when side-mounting due
to the tanks being lower on the diver and dropping the center of gravity towards
the feet then more of the ballast weight can be positioned higher on the Lumbar
Strap of the T Weight System or placing a Weight Pouch higher on the Pocket
Weight System to counteract this.
W W W . G O S I D E M O U N T . C O M
If more head up trim is required due then more of the ballast weight should be
positioned lower at the Waist Strap of the T Weight System

ment load are all one unit and move together.
W W W . G O S I D E M O U N T . C O M
Once you have made the final adjustments to your harness you can cut off any
extra webbing and burn the ends to seal them.
W W W . G O S I D E M O U N T . C O M
Remember to leave enough adjustment in the harness for changes in thickness of
exposure protection or any gain in weight.
W W W . G O S I D E M O U N T . C O M
All loose ends of webbing remaining can be held in place with the short sections of
bicycle tire inner-tube provided.
W W W . G O S I D E M O U N T . C O M
Many divers choose to get 2 Razor Harnesses, 1 for cold water diving in a Drysuit
and 1 for warm water diving in a Wetsuit so that they do not have to worry about
adjusting the harness or changing D rings etc. when they change environments.

without any further changes needing to be made.

1 The Razor T Weight System
1.2 Overview
W W W . G O S I D E M O U N T . C O M
The Razor T Weight System (TWS) is a modular 2 part weighting system designed
to make adding or removing weights from the Razor Harness quick and easy.
Part one allows weight to be added to the Lumbar area between the DSP and the
MBP and the second part allows weight to be added to the waist area between the
DAPs and the MBP.
You can use either part individually or use both together at the same time so you
have the option of using 3 different configurations according to diver preference:
a
Weights placed on the Lumbar Strap only
b
Weights placed on the Waist Strap only
c
Weights placed on both the Lumbar Strap and Waist Strap
W W W . G O S I D E M O U N T . C O M
56
1 The Razor T Weight System
W W W . G O S I D E M O U N T . C O M
The TWS is designed to use standard lead diving weights that are universally avail-
able. Up to four 3kg block weights can be added to the Lumbar Strap and two 3kg
blocks weights can be added to the waist strap.
W W W . G O S I D E M O U N T . C O M
So in total as much as 18kgs/40lbs can be added to the TWS although with a
properly weighted equipment configuration this amount should never actually be
required.
W W W . G O S I D E M O U N T . C O M
The advantage of using the TWS over a weight belt is that it reduces clutter and
allows you to place weight exactly where you need it to optimize trim.
W W W . G O S I D E M O U N T . C O M
Unlike a weight belt or weight pockets the weights are held very securely and there
is no chance of losing them accidently resulting in a potential for injury/DCS due to
a buoyant ascent in the open water. In the overhead environment loss of weights
would result in the diver becoming pinned to the ceiling unable to exit.
W W W . G O S I D E M O U N T . C O M
The TWS ensures weights are placed close to both the center line and the midline
of the body helping to maintain stability and reduce turning moments thus giving
the diver greater control while diving.
W W W . G O S I D E M O U N T . C O M
When the TWS is used in conjunction with BAT Wing then both the center of ballast
and center of buoyancy are very close to one another which also helps to maintain
stability and control while diving.
1.2 Overview
W W W . G O S I D E M O U N T . C O M
57
Weight can be added directly to the Razor Harness itself (see Razor Harness Manual) but
this is not recommended. The advantage of using the TWS over putting weights directly
on the harness is fourfold:
a Ease of use in removing or changing weights quickly
b Hardware on the harness will not have to be removed and replaced to add or
remove weights
c No adjustments to the harness webbing are required as the length of the webbing
stays the same and is not affected by adding or removing weights or using differ-
ent size weight blocks
d You do not have to travel with weight on the harness
W W W . G O S I D E M O U N T . C O M
Velcro closing weight pouches can also be used on the Razor Harness in conjunc-
tion with the TWS so that in an emergency divers have the option of ditching some
weight at the surface during open water dives. Ditching weight underwater is not
recommended as it may result in an uncontrolled buoyant ascent.
W W W . G O S I D E M O U N T . C O M
In an emergency if extra buoyancy is required at the surface while using SM con-
figuration negatively buoyant Steel tanks can be removed or Aluminium tanks can
be drained to 140bar/2000psi or below at which point they will start to become
positively buoyant.

2 Rigging the TWS Lumbar Strap
a Remove the BAT wing if fitted to the Razor Harness.
b Bolt the top of the Lumbar Strap webbing to the bottom hole of the DSP using one
of the supplied button head screws and a washer.
c If the BAT Wing is also normally attached at this bottom hole on the DSP then the
longer bolt found in the BAT Wing or Universal Spares kit will be required to fix
both the Lumbar Strap and the BAT Wing to the same mounting point.
d Slide block weights onto the webbing and position them correctly on the Lumbar
strap between the DSP and the MBP to optimize trim. Ideally weight should not be
placed above the Lumbar Strap Tri-glide so as not to interfere with the SM Bungee.
e Up to 4 block weights can be added to the Lumbar Strap. If more head down trim
is required the weight can be moved closer to the DSP or the heavier weights can
placed at the top of the Lumbar Strap. If more head up trim is required weight can
be moved closer to the MBP or the heavier blocks placed lower on the Lumbar
Strap.
f Feed the free end of the webbing through the top slot of the MBP (the top slot “A”
on the MBP is cut slightly wider than the other slots to accept the Lumbar Strap
easily) and double the webbing back over.
W W W . G O S I D E M O U N T . C O M
59
2 Rigging the TWS Lumbar Strap
g The extra webbing can cut off and sealed by burning the cut end. Be sure to leave
enough extra webbing to add more or larger weights in the future if necessary.
h The webbing can be finished off by feeding it back through the bottom block
weight if required although this is not really necessary as it will end up inside the
Neoprene Wrap.
i It is very important that the Lumbar strap of the Razor Harness determines the
distance between the DSP and the MBP not the Lumbar Strap of the TWS. Make
sure that the TWS Lumbar strap is not pulled tight and is the same length with the
weights fitted as the Lumbar strap of the Razor Harness.
j Fit the Neoprene Wrap around the weight blocks on the Lumbar Strap of the TWS
and the Lumbar Strap of the Razor Harness so that they are both solidly locked
together. Ideally the Velcro closure of the Neoprene Wrap should be positioned
on the inside of the Razor Harness against the divers back. The loose end of the
Lumbar strap should be secured inside the Neoprene wrap. The Neoprene wrap
should not be placed around the webbing loop below the DSP so as not to inter-
fere with the SM Bungee.
k The Neoprene Wrap can be cut down in two places in between the guide stitching
if required allowing the following configurations:
• Three single weight block wraps
• One double and one single weight block wrap
• One triple weight block wrap
Be sure to only cut between the stitching tramlines otherwise the edges of the
neoprene will fray.
l Double check all fittings on the TWS are secure and refit the BAT Wing.

3 Rigging the TWS Waist Strap
a Remove the BAT wing if fitted to the Razor Harness.
b Slide the Waist Strap of the TWS under the webbing of the Razor Harness that
passes through slots A and B of the MBP and bolt it into the hole in the middle of
the MBP using one of the supplied button head screws and a washer.
c Slide one block weight onto either side of the Waist Strap webbing. Up to a maxi-
mum of 3kgs can be used on either side. The amount of weight used should be
equal either side.
d Bolt the outside grommets into the DAPs on either side using 2 of the button head
screws and washers supplied. With small weight blocks use the two inside grom-
mets and with large block weights use the 2 outside grommets.
e The DAPs can be moved on the Razor Harness either closer to or further away from
the MBP as required to get a good fit with the Waist Strap of the TWS.
f Neoprene Wraps are not required for the Waist Strap
g Double check all fittings on the TWS are secure and refit the BAT Wing.

4 Weighting and Trim
W W W . G O S I D E M O U N T . C O M
It is very important to dive properly weighted and trimmed out in a well balanced
equipment configuration. This will make your diving both safer and easier.
W W W . G O S I D E M O U N T . C O M
Tank selection is important in helping to achieve correct weighting.
W W W . G O S I D E M O U N T . C O M
Diving in cold water with a Drysuit and thick undergarments it is recommended to
use low pressure Steel tanks as the primary SM tanks which will help to offset the
extra positive buoyancy of the exposure protection.
W W W . G O S I D E M O U N T . C O M
High pressure Steel tanks are not recommended as they tend to be too negatively
buoyant and make handling SM tanks underwater very difficult.
W W W . G O S I D E M O U N T . C O M
Diving in warm water in a wetsuit it is recommended to use Aluminium primary
Side Mount Tanks so as not to be excessively over weighted.
W W W . G O S I D E M O U N T . C O M
Aluminium tanks should always be used for stages and deco tanks so that as you
add extra tanks to your configuration you do not become excessively over weight-
ed.
W W W . G O S I D E M O U N T . C O M
62
4 Weighting and Trim
W W W . G O S I D E M O U N T . C O M
To determine your correct amount of ballast the following weighting check
should be carried out:
1. Enter the water wearing all of your equipment including the primary SM tanks
2. Completely deflate your Bat Wing and your Drysuit if you are using one
3. While holding a normal breath stop kicking and add enough weight until you
sink to eye level. When you exhale you should submerge completely.
4. If you are using full tanks you will need to add a little more weight to compen-
sate for the weight of the gas in the tanks that will be used during a dive.
5. Now that the correct amount of weight has been established submerge and
attempt to hover in a horizontal position while moving the weight up or down
the torso until the ideal position is achieved to maintain comfortable trim.

After a few dives as you become more relaxed and comfortable diving your Razor
Side Mount System you may find that you can reduce your ballast weight a little.
W W W . G O S I D E M O U N T . C O M
When you are correctly weighted you will need very little gas in your Bat Wing.

If you are diving in a Drysuit all your buoyancy can be controlled with the Drysuit
for the most part just using the BAT Wing for surface buoyancy and extra lift when
carrying heavier equipment loads.

1 The Razor BAT Wing
Once your Razor Harness and T Weight System have been set up then you can
attach the BAT Wing to the Harness.
The BAT Wing should be worn with the Primary Wing on the outside and the
Backup Wing on the inside.
This makes finding both the Primary and Backup wing dump valves easier and
allows both to be vented more effectively and the Backup
wing is very well protected.
The design of the BAT wing places the position of the
dump valve and the inflator elbow in a well protected
low profile position between the Side Mount tanks
and the diver’s body.
In addition the outside material of the wing is not placed
between a hard object such as the dump valve and
the ceiling of a cave, or a sharp object in a wreck
for example where it may be more prone to
damage.
In the very unlikely event that the dump
valve or inflator elbow or large diam-
eter inflation hose should be dam-
aged these components are easily and
cheaply replaced which is not the case
if the wing material is damaged.
The BAT Wing is supplied with a 19”
long large diameter inflation hose
and a short LPI hose.
This configuration should fit just
about everyone but shorter large
diameter inflation hoses of 16” or
13” and LPI hoses of 8” or 4” can be
purchased separately in order to
customize hose lengths if required.
The dump valve and the large diameter inflator hose elbow have compa-
tible fittings and can be positioned on either the left or right
hand side of the BAT wing according to diver preference.
1.2 Overview
1 The Razor BAT Wing
Normally when using a Drysuit the dump
valve will be positioned on the left hand side
of the wing with the large diameter Inflator
hose on the right hand side of the wing. The
large diameter inflation hose will deliver in
front of the diver across the chest from the
right hand side with the LPI hose delivering
from the regulator on the right SM tank.
1.2 Overview
1 The Razor BAT Wing
When using a wetsuit normally the fittings
should be switched so that the large dia
meter inflator hose is on the left hand side
and the LPI hose can deliver from the regu-
lator on the left hand Side Mount tank.
1.2 Overview
1 The Razor BAT Wing
The BAT wing is supplied
already set up in this configuration.
When changing the fittings make sure that they are not cross
threaded when screwing them in. The best way to do this is
to turn anti clockwise until the threads drop into position
and then tighten gently. No force should be used to get the
threads started.
1.2 Overview
1 The Razor BAT Wing
When the Inflator hose is unscrewed remember
to also take out the sealing O ring and replace
it in the other fitting so that the flat
side of the inflator elbow will seal against
the flat side of the O ring.
The inflator elbow is keyed and it is
important that it drops into position
so that it will seal on the O ring
when the fitting is screwed
back into place.
The orientation of the elbow can be
adjusted so that the large diameter
inflation hose routes comfortably
under the arm and across
the chest.
To do this start the threads a couple of
turns but do not tighten them until the
correct orientation of the elbow is
achieved making sure the keyed
flange drops into place to
ensure a seal and then
tighten fully.
Once fitted pressure
test the seal by
inflating the wing
and making sure
it is airtight.
1.2 Overview
1 The Razor BAT Wing
When replacing the dump valve it is important that the spring is
located in the right position in the center and can move freely so
that the valve does not stick in the closed position.
Hold the dump cord and spring under
a little tension as you screw the fitting
back into place.
After tightening the dump valve
fully check to make sure that it
operates correctly and that the
spring moves freely when the cord
is pulled.
Check correct operation of
the wing by inflating and
deflating it and making sure
there are no leaks from either
of these fittings before going diving.
1.2 Overview
1 The Razor BAT Wing
You will need the following tools to rig your Razor BAT Wing:
2 Rigging the Razor BAT Wing
2.1 Tools
A hex wrench to fasten the button head screws.
(included with the complete system in the
Universal Spares Kit.)
A lighter to burn and seal the ends of the
cut webbing and elastic bungee cord.
A knife or scissors to cut the harness
webbing and the elastic bungee cord.
The top of the BAT Wing bolts into the DSP of the
Razor Harness and should be positioned so that
the waist bungee cord and dump valve / infla-
tor elbow are at the height of your belly button
just above the waist strap of the Razor Harness.
Depending on the individual setup the top of the
wing can be bolted directly into the DSP or into the
Bungee Triglide if required to get a perfect fit.
Ideally the top hole in the DSP should be
used to leave the bottom hole free to
attach the Lumbar Strap of the T Weight
System but you can attach both the
BAT Wing and the T Weight System
to the same hole either at the top or
bottom of the DSP using the longer
button head screw provided if
required.
Step 1: Adjusting and Attaching the top of the BAT Wing
to the DSP of the Razor Harness
2 Rigging the Razor BAT Wing
1 A simple overhand knot
tied into the end of the
bungee cord will hold the
right hand side bungee in
place. This knot should be
on the inside of the wing.
B On the left hand side of
the wing a short waist bun-
gee cord is held in place
with 2 overhand knots tied
either side or the wing
grommet to secure it.
The BAT Wing Waist Bungee is designed to secure the sides
of the BAT Wing in a low profile streamlined position even
when the wing is inflated and still give easy unrestricted
access to all of the Razor Harness attachment points.
The waist bungee on the right hand side of
the BAT wing should have a long loop with
a small snap bolt attached to it. This will
feed across the waist and through the loop
of the crotch strap of the Razor
Harness and clip into the
short bungee loop attached
to the left hand side of
the BAT wing.
Step 2: Attaching and Adjusting the BAT Wing Waist Bungee
2 Rigging the Razor BAT Wing
A
B
The waist bungee should be fairly snug with the wing completely deflated and
both bungee cords will need to be adjusted to achieve the correct length and
tension to keep the BAT wing in a nice low profile position when it is inflated
and to prevent it from floating away from the divers body.
It will take a little bit of trial and error to get the length/tension correct so leave
the bungee cords long to begin with and do not tie the knots too tight so that
they can be released and moved easily if necessary.
Once the correct length is achieved then any excess bungee can be cut off and
the ends of the cords burnt to seal them and the knots snugged tight.
Step 2: Attaching and Adjusting the BAT Wing Waist Bungee
2 Rigging the Razor BAT Wing
The BAT Wing Rear Bungee is designed to secure the bottom of the
BAT Wing in a low profile streamlined position even when the wing
is inflated and still give easy unrestricted access to all of the Razor
Harness attachment points.
The Rear Bungee is secured to the BAT Wing with the Wing Tab and
the BAT Wing can be quickly and easily removed from the Razor
Harness by undoing the button head screw leaving just the Wing
Tab and bungee cord still attached to the MBP.
The bungee cord is attached to the Wing Tab with a Lark’s Head
Hitch (aka Lanyard Hitch). The bight of the Larks Head should
be on the outside of the wing tab.
Step 3: Attaching and Adjusting the BAT Wing Rear Bungee
to the Razor Harness
2 Rigging the Razor BAT Wing
The Wing Tab can also be removed from the bungee cord if required by passing the
hitch of the Lark’s Head Hitch back over the body of the Wing Tab which will just
leave the bungee cord attached to the MBP.
Step 3: Attaching and Adjusting the BAT Wing Rear Bungee
2 Rigging the Razor BAT Wing
The bottom of the BAT Wing with the Wing Tab
attached should line up with the slot of the Wing Tri-
glide of the Razor Harness that holds the Butt B ring
in position. The Wing Tri-glide can be moved up or
down the crotch strap webbing of the Razor Harness
to achieve the desired location.
This ensures that the Butt B ring will not be covered
by the BAT Wing and will remain accessible at all times
even with the wing fully inflated.
The free ends of the bungee cord coming from
Lark’s Head Hitch on the Wing Tab should be
passed through the slot of the Wing Tri-glide
attached to the Razor Harness and then run up
to the MBP and passed through the two holes
either side of slot B.
The bungee cord can be locked in place with a
simple overhand knot tied on the inside of the
MBP.
The bungee cord should have some tension on it
with the BAT Wing completely deflated so that it
will be held in a streamlined low profile position
when inflated and will pull tight when deflated.
It will take a little bit of trial and error to get the
length/tension correct so leave the bungee cords
long to begin with and do not tie the knots too
tight so that they can be released and moved
easily if necessary. Once the correct length is
achieved then any excess bungee can be cut off
and the ends of the cords burnt to seal them and
the knots snugged tight.
Step 3: Attaching and Adjusting the BAT Wing Rear Bungee
2 Rigging the Razor BAT Wing
Step 4: Adjusting and Attaching the Inflation Hose
2 Rigging the Razor BAT Wing
With the BAT Wing now attached to the Razor Harness the harness should be put
on so that the large diameter inflation hose and power inflator can be correctly
positioned. The large diameter inflation hose with the power inflator can be con-
figured to use from either the right or left hand side.
This can be changed easily to a left hand delivery
orientation if required by removing the 2 cable ties
locking the power inflator in place and then rotating
it 180 degrees before fastening with 2 new cable ties
to resecure it in place.
The BAT Wing is supplied with the large diameter
inflation hose and power inflator delivering from the
right hand side but it can be easily changed to deliver
from the left hand side if required as previously
noted.
The “clocking” of the power inflator is also supplied
with a right hand delivery orientation with the oral
inflation mouthpiece facing up towards the diver
with the power inflator button and Schrader valve on
the underside.
Step 4: Adjusting and Attaching the Inflation Hose
2 Rigging the Razor Harness:
The oral inflator mouthpiece should now face up towards the diver along
with the power inflator button and Schrader valve.
The large diameter inflation hose will run over the kidney area under the arm
and across the lower chest. The end of the Power inflator will be attached to
the D ring on the opposite shoulder with a loop of bungee cord tied with a
Fisherman’s knot through the loop of a small swiveling snap bolt.
The bungee loop can be positioned between the large diameter inflation
hose and LPI hose while diving so that it is securely retained.
The LPI hose to the power inflator should route directly across the chest
from the 5th port in the end of the swiveling turret of the regulator first
stage.
It will run under the large diameter inflation hose.
Step 4: Adjusting and Attaching the Large Diameter Inflation
Hose of the Primary wing to the Razor Harness
2 Rigging the Razor BAT Wing
The large diameter inflation hose can
be secured to the lower shoulder
strap of the Razor Harness below
the shoulder D ring using the
wide Neopren Logo Wrap pro-
vided with the BAT Wing.
Please note that the BAT Wing Logo
Wrap which has to go around the large
diameter inflator hose as well as the web-
bing of the Razor Harness is larger than the 2
Logo Wraps that come with the Razor Harness.
They should not be confused as they are not
interchangeable.
The orientation of the keyed hose elbow can be
adjusted as noted earlier to ensure a stream-
lined comfortable routing of the large diameter
inflator hose. This is done by loosening the lock-
ing ring a few turns until it is possible to lift out
the locking plate of the elbow then rotating it
until it locks back into the desired orientation
and tightening the locking ring ensuring that it
has bottomed out properly and is forming a good
seal.
The oral inflator of the Backup wing should be routed over the right shoulder
and can be held securely in place by passing it under the long neoprene logo
wrap and the bycicle inner tube on the right hand shoulder of the Razor Harness
webbing.
The hose should bend towards the center of the chest just above the right
shoulder D ring and should be long enough to reach the mouth comfortably.
It can be held in place in a clean streamlined fashion by passing it through a
couple of bicycle tire inner tubes placed around the large diameter inflation
hose spaced a few inches apart.
Any excess hose can be cut off to customize the length. Remove the bite on
mouthpiece, cut the hose to the desired length and then replace the mouth-
piece.
Step 5: Positioning the Oral Inflator Hose of the Backup Wing
2 Rigging the Razor BAT Wing
The mouthpiece can be glued in position when you are happy that you have the cor-
rect length. Spare mouthpieces are available and it is recommended to carry one in
your Razor Expandable Pouch in case you should lose it while diving.
In the event it should be lost while diving and you have no replacement it will have
no effect at all unless you are actually using the Backup wing.
The only problem then will be that the hose will tend to vent gas when you are in
a head up position such as when ascending. This can be prevented by placing your
finger over the end of the hose and releasing it when you wish to vent gas to adjust
buoyancy or slow an ascent.
Step 5: Positioning the Oral Inflator Hose of the Backup Wing
2 Rigging the Razor BAT Wing
Additional to the weights on the T Weight System you can add weights easily to the
system by adding weight pockets to the pocket weight layer on the BAT wing.
The pouches can be bought seperately at our online shops or along with our
dealers
Detailed information on how to juggle with weights you will find in the "Razor
Pocket Weight System" manual
Step 6: Adding weights to the Pocket Weight Layer
2 Rigging the Razor BAT Wing
Place the pockets against your back if you want ...
... to easy adjust the weights of your students even in the
water by adding some more weights left and right
top find out the right amount to use
... if you want to find out the right amount of
weight to use for yourself an easy and
quick way.
Step 6: Adding weights to the Pocket Weight Layer
2 Rigging the Razor BAT Wing
After you know the exact weight place the pockets between the weight layer and
the wing itself.
You can distribute the weight pockets depending on your needs of horizontal trim
or comfort.
Step 6: Adding weights to the Pocket Weight Layer
2 Rigging the Razor BAT Wing
Once you placed the pockets on the wing and for example you have to leave the
weights after a day of diving on the boat, then just open the pouches and take the
weights out, ready to just fill them in the next day.
Step 6: Adding weights to the Pocket Weight Layer
2 Rigging the Razor BAT Wing
Only use one wing at a time either the Primary or the Backup.
Make sure the wing you are not using is completely empty while diving so that you
only have 1 air space to control.
The Primary wing can be inflated in the following ways:
• By using the power inflator connected to a tank with an LPI hose
• By oral inflation by holding down the dump button of the power inflator and
blowing into the mouthpiece
The Primary wing can be vented in the following ways:
• By using the pull dump while rolling the body to the opposite side when in a
horizontal position to get the dump valve to the highest position of the wing
• By using the dump valve on the power inflator when in a head up position
The Backup wing can only be inflated orally using the bite on mouthpiece.
Not having a power inflator connected to the Backup wing avoids any problems
associated with a mechanical failure or accidental inflation of the wing resulting in
a potential buoyant ascent.
To use the oral inflation hose place check the next page.
The Backup wing can be deflated in the following way:
• By holding the oral inflation hose at the highest point and pinching gently on the
bite valve between thumb and forefinger to open it.
If you are having trouble venting air from the oral inflation tube check that this
dump valve is at the highest position of the wing, that you are pinching it in the
correct orientation across the horizontal axis and that you are pinching at the very
end.
Step 7: Correct Use of the BAT Wing
2 Rigging the Razor BAT Wing
To use the oral inflation hose place the very end of the bite on mouthpiece
between your teeth horizontally and make a seal around it with your lips.
Now bite down gently to open it and blow into the hose. No force should be
required.
If you are having difficulty inflating the wing check the orientation of the bite
on mouthpiece as it will only open when you bite on it in the horizontal axis.
Also make sure that you are biting at the very end of the mouthpiece as it will
not open if you are biting further up.
You should practice doing this before you go diving until you become familiar
and comfortable with the technique.
Step 7: Correct Use of the BAT Wing
2 Rigging the Razor BAT Wing
After diving both the Primary and Backup wings should be drained of any water
that is inside and partially inflated to dry.
Both Primary and Backup wings can be drained of water in exactly the same way
air is vented from them although it is easier if you orally inflate them a little first
so that you can force any water out under pressure.

1 The Razor Expandable Pouch (REP)
1.2 Overview
W W W . G O S I D E M O U N T . C O M
The completely new REP has been specifically designed to be butt mounted which
is the most streamlined and easiest to access location in SM configuration.
W W W . G O S I D E M O U N T . C O M
Pockets on the waist are difficult to access due to the placement of the SM tanks
and become an entanglement hazard in low areas.
W W W . G O S I D E M O U N T . C O M
Thigh pockets are also difficult to access due to the placement of the SM tanks and
will also have the tendency to push the bottom of the tanks away from the diver's
body resulting in “A Framing” and a greater risk of the tanks getting ratcheted in
small areas.
W W W . G O S I D E M O U N T . C O M
The REP should be clipped off to both of the DAPs with the 2 double ender’s
provided and will hang just below the BAT Wing with the Butt B Ring positioned
between the bottom of the wing and the top of the pouch allowing easy unob-
structed access to the B Ring as well.
W W W . G O S I D E M O U N T . C O M
The pouch will rest on top of a butt mounted primary light if one is being used and
anything clipped off to the Butt B Ring will be lie on top of it.
W W W . G O S I D E M O U N T . C O M
The way that the REP is attached with a double ender clipped off to each of the
small stainless steel D Rings sewn into the REP and then each double ender clipped
to the DAPs on the Razor Harness provides a very solid secure attachment which
will prevent accidental loss of the pouch.
W W W . G O S I D E M O U N T . C O M
Although this is a metal to metal connection each double ender can eas-
ily be removed at either the DAP or the Pouch D Rings in the very unlike-
ly event that one side of either double ender should jam closed.
In addition the D Ring can be cut free if required as a last resort.
W W W . G O S I D E M O U N T . C O M

1 The Razor Expandable Pouch (REP)
W W W . G O S I D E M O U N T . C O M
This position also prevents the REP from swinging from side to side while swim-
ming or getting caught between the diver’s body and the SM tanks.
W W W . G O S I D E M O U N T . C O M
The REP can be either used in situ or unclipped and brought to the front so that the
diver can see exactly what they are removing or replacing from the pouch which is
not possible with thigh or waist mounted pockets.
W W W . G O S I D E M O U N T . C O M
The REP can also be clipped off temporarily to both the Shoulder D Rings while
working with the contents if required which allows the diver to keep both hands
free and allows easy access to and good visibility of the contents.
W W W . G O S I D E M O U N T . C O M
The REP can be clipped off temporarily using just 1 double ender to the Butt B Ring
or either of the DAPs if required but will tend to swing in this position while swim-
ming.
W W W . G O S I D E M O U N T . C O M
The REP can be kept as flat and streamlined as possible or expanded considerably
by pulling open the Velcro closures around all four edges.
W W W . G O S I D E M O U N T . C O M
Even squashed flat the pouch has quite a large volume and will hold a considerable
amount.
W W W . G O S I D E M O U N T . C O M
The back of the REP has a large mesh pocket with Velcro closure and a center tab
to make opening it easier when wearing thick gloves. This was specifically designed
to carry slates/wet notes and dive tables/laminated deco plans.
W W W . G O S I D E M O U N T . C O M
The top zip of the REP is very robust and has a large tab to make operation with
gloves easier and it opens across the full length to the pouch giving easy access to
the contents.

1 The Razor Expandable Pouch (REP)
W W W . G O S I D E M O U N T . C O M
The REP has 2 internal Velcro closure pockets on the inside of the front panel which
were designed to carry small items such as a backup cutting tool like the EZZYCUT
or your Spare SM Bungee.
W W W . G O S I D E M O U N T . C O M
In addition there are internal fixing points on both sides of the REP and a length of
bungee cord for a lanyard which can be set up in any of the following ways depend-
ing on diver preference:
1. one loop tied between both attachment points
2. two small loops tied either side of the pouch
3. one large loop tied just to an attachment point on one side of the pouch
W W W . G O S I D E M O U N T . C O M
The bungee lanyard can be secured to the attachment point by passing one end of
the bungee cord through the webbing loop and then tying both ends together with
a Fisherman’s Knot.
W W W . G O S I D E M O U N T . C O M
The Spare SM Bungee can also be clipped off to one of these internal attachment
points if desired.
