Buoyancy compensators STREAM, CUB,
STREAM RING and RING
Denition of Terms
Buoyancy compensator – a device for adjusting buoyancy that
is comprised of a wing and a backplate.
Wing – a part of the buoyancy compensator comprised of a bladder
ination mechanism, and safety valve.
Backplate – usually a stainless steel, aluminium or plastic plate
equipped with harness, D-rings, and other parts designed to carry
the main cylinders.
Introduction
Before using the compensator, read the instructions thoroughly. Incorrect us-
age, maintenance, or damage to the compensator may render the warranty
void, and may also result in a dangerous situation, injury or death.
Use the compensator only for the purposes for which it is designed. The
STREAM Series compensators are designed for diving with double cylinders.
The CUB/RING Series Compensators are for diving with single cylinders.
Make sure you always use a compensator of the appropriate size. A compen-
sator that is too big can cause problems during deation. One that is too small
might not provide sufcient buoyancy. The maximum recommended size of
cylinders to be used with the wing is written on a label on the wing, and in the
compensator description.
The buoyancy compensator is not a life preserver. It does not maintain the
diver in a face-up position. It is not designed to maintain the diver’s face above
the surface should he become unconscious or immobile. For this reason, it is
important to follow the rules of safe diving, and always dive with a companion.
Do not inhale from your compensator. The inner bladder can be dirty, or contain
contaminated air that could cause serious health problems.
Do not inate the compensator to the maximum. This will shorten its lifespan. A
failure of the safety valve may result in damage to the compensator, and injury
to the diver.
Before each dive, it is critical to go through all safety procedures in order to
detect possible damage to the compensator. A good instructor can acquaint you
with these procedures.
Service and repair of the compensator must be provided only by factory trained
personnel. Unauthorised service not only voids the warranty, but may also en-
danger the health and life of the user.
If you do not have sufcient experience in diving with this type of compensator,
go through appropriate training, and then test the compensator in the controlled
environment of a swimming pool or shallow water.
Warning: The manufacturer is not responsible for any damage or in-
jury to a user of the buoyancy compensator that is caused by incor-
rect usage or inappropriate adjustment that affects its functioning.

Fitting the Harness
The backplate that forms part of the compensator is supplied with a
high-quality harness that is threaded through in a way that ensures proper
system functioning. Do not change the way the harness is fed through the
backplate. If you do try to take the harness out, remember exactly how it
is threaded through in order to prevent interference with the functioning of
the whole system.
When tting the crotch strap, the back D-ring must t correctly as well. Ad-
just it by shifting it along the harness high enough so that it does not disturb
you while swimming, but low enough to allow you to reach it even with the
cylinder (or double cylinders) mounted on. When adjusting the D-ring, take
into account the possibility of bigger and longer cylinders than the ones you
usually use. Before using it for the rst time, adjust the harness so that the
buoyancy compensator is well tted on your back, and does not move. The
strap can be adjusted by gradually moving it across the stoppers placed on
the back side of the backplate.
Once the harness is adjusted, the cylinder on your back should be in a po-
sition that allows you to tilt your head back, and to reach and control the
cylinder valve (test this in the water). Proper placement of the cylinder re-
sults in the right trim. If the gear outweighs the lower parts of your body, slacken the crotch strap a bit and tighten
the shoulder straps. This will push the cylinder closer to your head, and your centre of mass will be higher. If the
gear outweighs the upper part of your body, do the opposite.
When tting the main strap, ordinary clothes such as pants and a T-shirt are sufcient. Put the backplate (without
the wing) on your back, and run the crotch strap between your legs. The belt buckle on the waist strap must pass
through the crotch strap loop and rest on the right side of the crotch strap when fastened. The waist belt and
crotch strap should be as snug as possible, but still comfortable.
Fit three ngers under the strap at the level of your collarbone. If there is not enough space, slacken the straps.
If it is too loose, shorten the strap by moving it in front of the stoppers (buckles with two holes) on the back side
of the backplate. Repeat the whole procedure until you can t three ngers under the straps without force, but
without the straps becoming too loose. At the same time, you should be able to pull your arms out. Check to see
that both straps are the same length. Once the straps are adjusted, the backplate should be high enough to allow
you to reach its upper edge; the top should be just below the second vertebra.
Once you t the main straps, you must adjust the D-rings. The chest D-rings should be as low as possible, while
still allowing you to cross your arms over your chest comfortably. The D-rings should be high enough for you to
reach the left ring with your left thumb, and the right ring with your right thumb. The D-ring on the left side of the
waist strap should be roughly on your hip.
Continue by passing the left side of the waist strap through the belt buckle in such a way that the belt buckle can
pass through the crotch strap (see the picture). Guide the strap through each opening in the buckle, starting with
the outside one. We recommend securing the strap by passing it again through the rst opening.
Do not shorten the straps after the rst tting. Wait until you test your gear in the water. You will be doing addi-
tional adjustments for 3 to 5 dives until the gear is tted properly on your back – as snug as is comfortable. Only
then can you shorten them to leave an extra 10 to 15 cm on each side. We recommend nishing off the right side
of the waist strap in an arc. When shortening straps do not forget to nish them off properly so that they do not
fray. You can use a cigarette lighter or a candle to do this, but make sure that you do not create a thick layer on
the end that would hinder threading the strap through the buckles and stoppers.
The backplate also includes a crotch strap with two D-rings. Its length is adjusted by moving the strap through
the back D-ring. We also recommend tightening the strap securely at the back D-ring, making sure to prevent it
from coming untied (especially in the case of frequent scootering). The crotch strap should be adjusted so that
the cylinder does not slide on your back, while still being comfortable.
Initial Assembly of the Compensator
Assembly of the compensator with a single cylinder
We recommend rst bolting the wing and the backplate loosely together. Run the bolt through the wing and then
the backplate in such a way that the nut faces your back and the bolt head shows up on the wing. Do not tighten
Use of the crotch strap and waist strap, po-
sitioning of the knife and belt buckle

the bolt yet; the wing should be loose enough on the backplate to facilitate the assembly. Attach the wing in such
a way that the logo can be seen while looking at the backplate; that is, the wrap hose joint is on the opposite
side from the backplate.
Pass the straps with the buckle designed to hold the cylinder through a strap slot in the wing (1). The Velcro on
the strap must be turned to the outside, in the direction of the wing’s perimeter. Continue by threading the strap
through a corresponding horizontal slot in the backplate (2), and then through a slot on the other side of the
backplate´s bending (3). Then thread the strap through a strap slot in the wing (4, 5). Move the strap so that the
Velcro close to the fastener runs through both strap slots of the wing. At the fastener, leave about 10 cm of the
strap without threading it through the wing. Follow the same procedure for the remaining strap and slots.
After that pull the strap through the buckle in accordance with the following pictures:
When nished, both parts of the Velcro should line up and ensure that the fastener does not unfasten.
If you do not change the wings on the backplate, we recommend bolting them to the backplate. You have already
used a bolt before threading the straps. Tighten it rmly, and do the same with the other one. The bolt head
should protrude above the eyelet in the wing as little as possible so that the surface of the cylinder does not get
damaged.
Threading the strap through the belt buckle
Thread the strap through every opening in the buckle, as shown above.
This will ensure that the strap points backward and cannot become loose spontaneously
Passing the strap through the wing and the backplate:

If you decide to use a buoy pocket, the next step is the installa-
tion of the pocket on the backplate. For the assembly, use the
at-headed bolts provided. Lay the backplate down in front of
you, and place the pocket on it so that you can see the logo. The
straps of the backplate should t in the narrowing on the pocket.
Continue by bolting the pocket to the backplate with the bolt head
facing you, and with the nut on the other side of the backplate (by
the wing). The padding provided goes under the bolt nuts. We rec-
ommend tightening the bolts rmly, and securing them by atten-
ing. We recommend using all eight bolts on the pocket perimeter.
This will prevent the pocket from creasing and causing discomfort,
and the buoy will be well secured.
Assembly of the compensator using a double cylinder
Using a double cylinder requires only one adjustment – attaching
a buoy pocket to the backplate. Follow the same procedure as
in the case of single cylinder (described above). Before tightening the two lower bolts (close to the pocket
opening), we recommend trying to attach the double cylinder to the compensator. It is important to determine
whether you can bolt the wing nut on the bolt that comes through the double cylinder bands. If it is difcult
(usually it is in the case of the lower bolt), we recommend not using one of the bolts on the lower edge of the
backplate. Removing the unfastened side of the pocket allows you to reach the bolt, and attach the double
cylinder to the backplate.
Tips
Gear tting: Attach the cylinder to the compensator. The procedure
depends on whether you use a single or double cylinder, and whether
you use an adapter for a single cylinder or attach the cylinder directly
to the compensator.
Attaching inator: Pass the low-pressure inator hose under the two
rubber bands on the wrap hose. Continue by passing it under the rub-
ber band on the left strap of the backplate above the D-ring, and attach
it to the inator. This will ensure that the inator is oriented to your neck,
close to the collarbone where it will not interfere with the rest of the
gear, and where you can easily nd it.
Adaptor for a single cylinder: The CUB/RING wings do not require
using singe-cylinder adaptors.
Inspection Before Each Use
We recommend an overall visual inspection before each use. It is good idea to check whether the safety valve
and cap nut on the inator´s joint are well tightened. If not, tighten well. Check the function of inating and
deating, and the overpressure valve. Test the sealing of the whole system in the water.
Maintenance
After diving in the ocean, rinse the gear thoroughly with fresh water. The salt crystals might damage the inator
or safety valve, and cause them to become non-functional. If the compensator is dirty, clean it while paying
special attention to the ination mechanism and safety valve. No other maintenance is necessary. After every
dive, pour out the water that gets into the wing during deation.
Storage
Store the buoyancy compensator in a dry, dark place in such a way that the wing cover and hoses are not
strained in any way. We recommend laying the wing out on a at board.
Correct attachment of the inator hose

Inspections
We recommend doing the inspection described above before every use. We highly recommend having
a thorough inspection performed once a year by factory trained personnel.
Compensator Description
Backplate: The material is stainless steel.
The hole pitch for attaching a double cylinder
or adaptor for one cylinder corresponds to the
11 inches standard (approximately 280 mm).
The plate can be used with all types of DTD
wings and some from other manufacturers as
well.
Wing bladder: The material is CORDURA 560
with PU coating. It resists hydrolysis, low tem-
peratures, and hydrocarbons, and has low gas
permeability.
Wing cover: The material is CORDURA 2000
Inator mechanism: Simple joint without a deating valve. Wrap hose with inner lining prevents loosening and
stretching of the hose. Inator mechanism which allows 1) a regulated ination by pressing an inator button
(placed on the side) with varying force, 2) fast deating by pressing the button at the end of the inator, and 3)
inating of the wing by mouth.
Safety valve: Overpressure valve preventing damage or destruction of the wing by over-lling.
