1. IMPORTANT WARNINGS
1.1 General Warnings
WARNING
This manual must be read and understood entirely before using the product. It is advised
that you keep this manual in your possession during the entire life of your BC. FAILURE TO
READ, UNDERSTAND, AND FOLLOW THE PRECAUTIONS LISTED IN THIS MANUAL
COULD RESULT IN SERIOUS INJURY OR DEATH.
WARNING
When diving you must follow the rules and apply the skills taught by a recognized scuba
diving certication agency. Before taking part in any diving activity, it is mandatory to
have successfully completed a scuba diving course covering both theoretical and
technical aspects of diving.
WARNING
This instruction manual does not replace a diving instruction course!
1.2 Pre-Dive Warnings
WARNING
DO NOT DIVE with a BC that does not pass any of the Pre-Dive, Dive or Post-Dive
inspection points and tests. Diving with a BC that fails any of the listed check points could
result in the loss of buoyancy control while diving, resulting in serious injury or death.
WARNING
In accordance with European standards, our BCs can only be considered certied
where all components are present, as per the original SCUBAPRO conguration,
including the low pressure hose supplied.
Any variation of the original conguration invalidates conformity to European certication
standards.
WARNING
Ensure you have fully understood the jacket’s function and features and adjust the straps
appropriately before diving. If in doubt, ask your ofcial SCUBAPRO dealer for help.
WARNING
Do not attach an L.P. hose to a Scuba regulator high pressure (HP) port or to a gas supply
with pressure in excess of 200 psi (13.8 bar). This may result in damage or explosive failure
of the Ination Valve or Low Pressure Hose, which could result in injury or death.

English
1.3 Dive Warnings
WARNING
DO NOT DIVE with a BC that is damaged, leaks air or does not function properly. Terminate
any dive as safely and quickly as possible if the BC becomes damaged, leaks gas or does
not function properly.
WARNING
Special instruction in cold water diving practices and the specic use of this product in cold
water is required prior to cold water diving (temperatures below 10°C/50°F). This instruction
is beyond the scope of this manual.
WARNING
This product is designed to use air or helium/nitrogen/oxygen mixtures containing up to 40%
oxygen. Use of gas mixtures with increased oxygen, or the addition of other substances,
may cause corrosion, deterioration, premature aging or component failure of metal and
rubber parts. These actions may result in loss of buoyancy control or air holding integrity of
the BC, resulting in injury or death. Non standard gas mixtures may also present a risk of
re or explosion.
WARNING
The assembly of the system should only be done by a trained person such as an Authorized
SCUBAPRO Dealer to avoid incorrect assembly. After the assembly, a nal inspection must
be performed by an Authorized Dealer. Incorrect installation can cause serious injury or
death.
WARNING
Avoid prolonged or repeated exposure to chlorinated water, such as swimming pools.
Wash your BC immediately after any use in chlorinated water. Chlorinated water can
oxidize fabrics and materials on your BC, thereby shortening the life of the BC as well as
cause colors to fade. Damage and fading from prolonged exposure to chlorinated water is
specically not covered under warranty.
WARNING
Do not use your BC 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
THIS BC IS NOT A LIFE JACKET OR A RESCUE DEVICE.
Emergency face up oatation may not be provided for all wearers and in all conditions.

6
WARNING
Never breathe from your BC. Your BC may contain gas residue, liquid or contamination that
may result in injury or death if inhaled.
Keep water out of the bladder of the BC. Repeated use of the Oral Valve or Over Pressure
Valve may allow water inside the BC, reducing the amount of buoyancy provided by the BC.
This could result in injury or death. Drain all water out of the BC prior to every use.
WARNING
Wing-style BCs are built for a stable position underwater. The S-Tek is not a life jacket. Fully
inated, the S-Tek does not guarantee an unconscious diver will be in a safe, heads-up
position at the surface.
WARNING
When using a weightbelt with the crotch strap, you must place the weightbelt on top of
the crotch strap ensuring it can fall freely from your body. Failure to follow this practice will
prevent the weightbelt from being released and may result in serious injury or death.
WARNING
Keep sand and other contamination out of the mouthpiece of the TEK BPI. Under certain
conditions, contamination can cause the valve not to close completely. If this occurs
while diving, shake the TEK BPI while depressing the deate button several times. If the
valve leaks or remains inoperable, terminate the dive. Diving with a leaking Buoyancy
Compensator or with valves that do not operate properly may result in a loss of buoyancy
control that could result in injury or death.
WARNING
The deation device with the maximum outow of gas is the lower deation valve (g. 17)

5. S-TEK - SETUP AND ADJUSTMENTS
5.1 S-TEK PURE Harness (Stainless or Aluminium) Setup
The S-TEK PURE Harness offers two separate modes of use:
• Extender Mode on Shoulder Straps to provide easier doffing and donning (All
S-TEK PURE Harnesses are shipped in this mode).
• Fixed Mode on Shoulder Straps provides the most simple, secure attachment for
extreme diving.
5.1.1 Choosing the correct mode
Extender Mode
The S-TEK PURE Harness is shipped
in Extender Mode and uses the
exclusive S-TEK WEB-LOC to prevent
overtightening of the shoulder straps,
allowing you to ‘save’ the setting of
the Shoulder Strap each time you
don your harness. This system can
be personally tailored to you.
In this mode, the Shoulder Straps
can be loosened slightly once the
waist buckle is undone. Tri-glides
traditionally placed at the back of
the back plate have been removed,
allowing the webbing to slide through
the back plate. The WEB-LOCs (fig.1)
are added to the Shoulder Strap
webbing to set a minimum length,
preventing overtightening of the
Shoulder Straps when you tighten the
Waist Strap.
Overtightening your harness can
restrict movement and respiration.
Set the WEB-LOC to the correct
position by unclipping the lock
(fig.1-1, fig.1-2) and sliding it down
the Shoulder Strap to the position
that, once your harness is donned,
sets desired shoulder length while
allowing good freedom of movement
without restricting your harness and
breathing. Clip it closed (fig.1-3).
fig. 1 fig. 1-1
fig. 1-2 fig. 1-3

18
Fixed Mode
Although the S-TEK PURE Harness is
shipped in Extender Mode, a spare
Tri-Glide is included, should you want
to convert your harness to the Fixed
Mode.
In this mode, the Tri-Glide already
supplied in Extender Mode on the
right Waist Strap needs to be moved
to the traditional position at the back
of the back plate.
The spare Tri-Glide included with
the harness needs to be positioned
identically on the left side. You will
need to remove the Waist Buckle,
left-side Tri-Glide (fig.2 and fig.2-1)
with D-ring and place the spare Tri-
Glide (fig.2-2) in the same position at
the back of the back plate. Rethread
the left-side Tri-Glide (fig.2-3) with
D-ring and Waist Buckle once you are
happy with the Fixed Mode shoulder
strap length.
You can then remove the S-TEK WEB-
LOCs as described in the Extender
Mode section above as they serve no
purpose in the Fixed mode.
Should you wish to revert to the
Extender Mode, reverse the process
and keep the spare Tri-Glide safe
should you ever require the Fixed
Mode option later.

5.1.2 Shoulder Strap and D-Ring Location
While standing, don your harness.
Lift your elbows ensuring your arms
are parallel to the ground and point
your thumb toward the shoulder
strap (fig. 3) to get an indication of
the correct D-ring placement.
This placement is important for
having easy access to items clipped
onto the D-rings, including Stage
Cylinders.
Feed the webbing through the Tri-
Glide until you have created a loop
(fig.3-1). Move the Tri-Glide and
D-ring unit in the desired direction
along the shoulder strap (fig.3-2)
to locate it in the ideal position as
described above.
Note: Before this step, decide which
mode suits your requirement best;
Extender or Fixed mode. WEB-LOCs
and Tri-Glides should be removed
or added and placed in the correct
positions as described in the Mode
Section above.
5.1.3 Waist D-Ring (left-side) and Tri-Glide (right-side) Position
As a general rule, the Waist D-ring on the left side
of the S-TEK PURE Harness should be located in
line with an outer leg trouser seam (fig.4).
This D-ring is normally used for clipping off your
SPG and Stage Cylinders.
In Extender Mode, the distance between the WEB-
LOC and the Waist D-ring on your left hip (or the
Tri-Glide on your right hip), allows you to easily
loosen Shoulder Straps to remove your harness or
accurately tighten when donning your harness.
In Fixed Mode, the Shoulder Strap length is fixed.
To change the position, feed the webbing through
the Tri-Glide and Tri-Glide/D-ring unit until you
have created a loop (much the same as the
process described above in the Shoulder Strap
and D-ring section). Move in the desired direction
along the Waist Strap until placement is aligned
with an outer leg trouser seam.

5.2 S-TEK PRO Harness (Stainless or Aluminium) Setup
5.2.1 Shoulder Strap and D-Ring Location
While standing, don your harness. Lift your
elbows ensuring your arms are parallel
to the ground and point your thumb
toward the shoulder strap (fig.5) to get an
indication of the correct D-ring placement.
Adjustment of the Shoulder Strap length,
as well as the chest D-ring location, is
set using the excess webbing at the top
section of your S-TEK PRO Harness on
the back of the back plate (fig.5-1). We
recommend using this method for D-ring
shifting (rather than feeding the webbing
through the Monprene® Shoulder pads
and Tri-Glide/D-ring unit) in order to ensure
the TEK-LOC adjustment buckles on the
Shoulder Straps are in the correct position.
You should allow approximately 20cm
of excess webbing to ensure you can
re-adjust your harness depending on
thickness of exposure protection or
configuration changes.
Adjust the Shoulder Strap length or chest
D-ring placement by feeding the webbing
through the Tri-Glide (fig.5-2) so that, once
your harness is donned and the TEK-LOC
buckles are tightened, your D-rings are
in the correct location. Shoulder Straps
should be adjusted to allow good freedom
of movement without overly restricting your
harness and breathing.
Ensure you do not have more than 15-20cm
of excess webbing from the TEK-LOC
adjustable buckles (fig.5-3). Too much
webbing could increase drag and irritation!
