Introduction
Traditionally, owner’s manuals begin with statements such as, “Congratulations on
your purchase of our nifty new whiz-bang product…” Such statements are, of course,
entirely self-serving on the part of the manufacturer.
Nevertheless, the fact remains you’ve got one helluva BC on your hands. If you
follow the instructions in this manual, and give the product the care it deserves, it
should provide you with years of enjoyable service.
Before using your Transpac II, there are several things you must do.
These include:
 Obtain a minimum of entry-level open-water scuba diver training
and certication from a recognized diver-training organization,
such as ACUC, BSAC, CMAS, GUE, IANTD, IDEA, NASDS,
NAUI, PADI, SSI or YMCA.
 As part of this training, you must master all basic skills of buoy-
ancy control, including: proper weighting; ascents; descents; sur-
face swimming and resting; and establishing neutral buoyancy
under water. This training must also cover (both at the surface
and under water): the use of buoyancy-control devices (BCs); oral
ination of BCs; low-pressure ination of BCs; and deation of
BCs using a variety of methods.
 You must read and understand this manual and all other warnings
that accompany the product. If you do not understand some part
of this manual, contact Dive Rite using the information appearing
on the cover.
Misuse of the Transpac II can result in uncontrolled ascents,
descents or loss of buoyancy control. This, in turn, can cause serious
personal injury or death.
Before using your Transpac II in open water, wrecks, caves or under ice, there are
two things you must do. They are:
 Read and understand this manual in its entirety. There is very little, if any, informa-
tion here that does not pertain to you. Don’t risk missing vital information by

Transpac II Owner’s Manual Page 5
picking and choosing the data you think applies to you. Why take chances? Read
it all.
 Practice using your Transpac II in conned water before using it in more challenging
conditions. This advice really applies to any major piece of diving equipment. With
buoyancy-control equipment, it is especially important to practice adding and
venting air in a variety of positions. To omit this practice is to risk dangerous,
uncontrolled ascents.
Additional Warnings
The Transpac II is not a Personal Flotation Device
The Transpac II is not a United States Coast Guard-approved Personal Flotation
Device (PFD). It will not provide face-up otation for all users and conditions.
Do Not Modify Your Transpac II
Changes to the Transpac II or use of after-market accessories can prevent its proper
function or result in damage to the Transpac II.
Proper Assembly and Adjustment Required
 Do not use either the Classic Wings or Super Wings with single cylinders. When
using Rec Wings with single cylinders, always tighten the gusset control cord and
elastic strap to help prevent the air cell from wrapping itself around the sides of
the cylinder, trapping air. Failure to follow these instructions can prevent you from
venting air from your BC and may lead to uncontrolled ascents. This can further
result in serious personal injury or death.
 Before each use, soak the Transpac II’s tank bands in water and allow them to
stretch. Be certain that the end of each tank band faces inward and rests directly
against the tank(s). Each tank band must pass through the tip of its cam strap
buckle, and mate with the material on the outside of the strap. Failure to do so
can result in the bands loosening or coming undone during use, resulting in the
possible shifting or loss of scuba cylinders in or out of the water.
 Once you have attached your Transpac II to a single scuba cylinder, you should
pick the unit up by the BC and shake it up and down a few times. This will help
make sure that the tank is fastened in securely, and that the bands are tight enough
to help prevent them from coming undone accidentally, later on.
 Adjust the waist, shoulder and chest straps for a comfortable t. Properly tted,
the Transpac II should not restrict your breathing when any of its air cells are
fully inated.

Transpac II Owner’s Manual Page 6
Use Weight System Properly
 Gravity alone may not be sufcient to pull weights completely clear of the weight
pocket, other equipment or your body, thus enabling them to be jettisoned safely.
When jettisoning weights, always check to make sure the weight pockets are
completely empty, and that no weights are caught on, or entangled in, other
equipment. Whenever possible, hold any weight you are jettisoning away from
the body before dropping it. Failure to follow these instructions may result in
unsuccessful attempts at jettisoning weight which, in turn, can lead to the inability
to ascend to or remain at the surface.
 If you do install other pockets in addition to those of the weight system, make
certain these other pockets do not interfere with easy and rapid removal of weight
in an emergency. Failure to do so may result in unsuccessful attempts at jettisoning
weight which, in turn, can lead to the inability to ascend to or remain at the
surface.
 If you need a weight belt, remember to fasten the Transpac II’s optional crotch
strap rst, then put the weight belt on over it. Failure to do so will hinder your
ability to release your weight belt in an emergency.
Pre-Dive Inspection Required
The examinations described in this manual will help you identify equipment prob-
lems before unsafe conditions exist. Nearly all equipment-related diving accidents
are preventable by:
 Following the recommendations outlined in this manual.
 Having equipment regularly inspected and serviced by trained technicians at
factory-authorized repair facilities.
 Before each use, check all of your Transpac II’s tank bands and buckles, straps,
quick-disconnect clips and the cummerbund/waist strap for wear. Have an autho-
rized repair facility replace worn or damaged items before you use your Transpac
II.
 If your Transpac II fails to pass any of the tests outlined in this manual, or if you
have any doubt as to the safe and proper function of any of its components, do
not use it. Instead, have your Transpac II inspected and, if necessary, serviced by an
authorized repair facility before taking it in the water again.
Careful Ination/Deation Required
 Do not attach your Transpac II’s low-pressure inator hose to a high-pressure air
source, such as the HP (high pressure) port of a regulator. The Transpac II’s low-

Transpac II Owner’s Manual Page 7
pressure inator and its supply hose can only handle pressures of approximately
150 pounds per square inch/10 bar over ambient pressure.
Read your regulator manufacturer’s instructions concerning the proper con-
nection of low- and high-pressure hoses. Installation or changing of such hoses
should only be done by trained technicians working for factory-authorized dive
centers. Product damage can result from improper hose connection.
 Always inate Transpac II air cells slowly, both at the surface and under water.
Rapid ination under water can result in uncontrolled ascents. Uncontrolled
ascents can cause serious lung overpressure injuries, such as Arterial Gas Embolism
(AGE). Such serious overpressure injuries can result in death.
 Maintaining safe rates of ascent requires training and practice. The Transpac II air
cells’ overpressure relief valve does not control or prevent uncontrolled ascents.
 These instructions do not necessarily incorporate all the steps required, under all
conditions, to orally inate the Transpac II above or below the water. Oral ination
of BCs under water requires special training and practice. This should rst be
attempted under controlled conditions and the supervision of a certied instructor.
 Never breath from your Transpac II’s oral inator/manual deator mouthpiece.
Your Transpac II’s air cell may contain contamination or gas residue that may be
hazardous if inhaled.
 Use of the Transpac II’s oral inator/manual deator or overpressure relief valve for
deation may allow water to enter your Transpac II’s air cell. Repeated deation
of the Transpac II under water may allow enough water to enter the air cell to
substantially reduce the Transpac II’s lift capacity (buoyancy) or interfere with its
ability to allow the user to control buoyancy.
If you have questions regarding any of the information you nd in this manual
or—equally important—questions pertaining to information about the Transpac II
you cannot nd in this manual, contact your local authorized Dive Rite dealer. If
there is no authorized Dive Rite dealer in your area, contact Dive Rite directly, using
the contact information appearing on the front of this manual.
What Your Transpac II System
Will and Will Not Do
Before using your Transpac II, it is important you have a realistic perspective of what
it will and will not do.
What Your Transpac II Will Do
Your Transpac II is designed to do only the following:

Transpac II Owner’s Manual Page 8
 Provide divers with additional buoyancy while surface swimming and resting.
 Offset loss of buoyancy caused by exposure suit compression under water.
 Provide a means of mounting single and double scuba cylinders and common
accessories to the diver.
What Your Transpac II Will Not Do
Your Transpac II is not designed to do any of the following:
 The Transpac II is not to be used as a diver’s sole form of otation; divers should
have additional forms of otation, such as a neoprene foam wet or dry suits, to
provide buoyancy in case they need to abandon the Transpac II, or it malfunctions.
The Transpac II is not a United States Coast Guard-approved per-
sonal otation device (PFD). It will not oat an unconscious person in
a face-up position in all situations or under all conditions.
 The Transpac II is not a substitute for adequate swimming and scuba diving skills.
(Trusting your life to any single piece of equipment is just plain stupid.)
 It is not an emergency air supply. Do not attempt to breathe from the air cell
mouthpiece. The bladder may contain gasses or residues that are hazardous to
breathe.
 The Transpac II is not a lift bag. Attempting to use it as such places a diver at
extreme risk of nding him or herself in a dangerous, uncontrolled ascent.
If you have questions regarding the Transpac II’s suitability for a particular purpose,
contact Dive Rite at the phone numbers appearing on the front of this manual.
Transpac II Features
Here is an overview of some of the many features and benets your Transpac II
system offers you. (The numbers refer to the illustration on the next page.) You will
nd more specic information on these features throughout this manual.
1. Tank adjustment strap helps you mount the Transpac II harness on single
cylinders at the same height each time (works with Travel, Trek and Rec Wings).
2. Padded shoulder straps—available in ve different lengths—provide comfortable
t.

Transpac II Owner’s Manual Page 9
Figure 1: Key Transpac II features.
3. Shoulder strap attachment point enables you to add or remove D-rings from
shoulder strap.
4. Three one-inch/25mm D-rings along each side of harness provide attachment
points for light canisters, pony bottles and other equipment.
5. Self-closing “epaulet” on the left-hand shoulder strap helps you keep ination
hoses under control.
6. Grommetted mounting holes for doubles enable positioning of cylinders at
different heights.

Transpac II Owner’s Manual Page 10
7. Shoulder strap quick releases feature unique, “fail-safe” design.
8. Two-inch/50 mm D-rings on each shoulder are adjustable for height and bent at
a slight angle for better access. You may also add or remove D-rings from the
shoulder-strap webbing.
9. Shoulder straps are easily adjustable for length and t.
10. Mounting slots for two-inch/50 mm cam straps (included with harness) enable
use with single cylinders.
11. Two-inch/50 mm D-rings on each side of waist strap are adjustable. Waist strap
design enables easy mounting of pockets and other accessories. Transpacs also
come with a stainless-steel, quick-release buckle.
12. Padded cummerbund helps transfer cylinder weight to hips for better t and
comfort.
13. Shoulder strap base plates, made from stainless steel, allow users to move base
of shoulder strap back and forth for best t and performance. These plates are
pre-drilled to accept installation of special “Tek” D-rings for use with sidemount
or stage bottles.
14. Heavily padded lumbar support and padded waist band transfer weight to hips.
15. Attachment point for optional 1056D crotch strap.
Transpac II Components
Your Transpac II is not merely a BC, but rather a system of components that enable
you to customize your Transpac II for a variety of applications. In its most compact
form, you might use just the Transpac II harness and Travel Wings, for traveling to
a warm-water dive destination. At the other extreme, you might use the Transpac II
harness in combination with Super Wings, the optional crotch strap and stabilizing
plates, and a variety of pockets, for the most demanding technical diving.
This section will help you identify the components you presently own, and
those you may wish to add to your Transpac II at a later date.
Transpac II Harness
The Transpac II harness is the heart of the system. All other Transpac II components
attach to it. Transpac II Sizes The harness is available in ve sizes, ranging from
XS (Extra Small) to XXL (Extra, Extra Large). Size denotes shoulder strap length.
To ensure proper shoulder strap length, measure from at point at the top of the
shoulder to a point at the waist immediately below it, as shown in the accompanying
illustration. Be sure to allow for exposure suit thickness.

Transpac II Owner’s Manual Page 11
Size Range
XS 13.0 in/33 cm to 16.0 in/41 cm
SM 14.0 in/36 cm to 17.5 in/44 cm
M/L 17.0 in/43 cm to 22.0 in/55 cm
XL 18.5 in/47 cm to 23.5 in/60 cm
XXL For divers >75 in/190 cm; 250 lbs/110 kg
Figure 2: How to measure for shoulder strap length.
Small (S) and Extra Small (XS) Transpac harnesses come with back sections and
lumbar supports that are approximately 2.0 inches/5.0 cm shorter than those of
larger Transpac harnesses. This is the preferred size for any diver whose back-of-neck
to waist measurement is 17.0 inches/43 cm or less (a range that includes nearly all
women). Any combination of Transpac shoulder harness and standard or short back
section/lumbar support are available on special order.
Transpac II harnesses come with a padded “Tek” cummerbund that is in
proportion to the length of the shoulder strap. It is possible, however, to order your
Transpac II harness with a different size “Tek” cummerbund, or with the optional,
full-length “Sport” cummerbund described on page 19. These are also available as
after-market replacement items.
Tek cummerbund size ranges are:
Size Range
XS 24 in/60 cm to 28 in/70 cm
S 28 in/70 cm to 34 in/85 cm
M/L 32 in/80 cm to 40 in/100 cm
XL 38 in/95 cm and up
XXL For divers over 75 in/190 cm; 250 lbs/110 kg
The Transpac II harness comes with a “Sport” back pad/lumbar support, as shown in
Figure 3 (next page). An optional “Tek” back pad/lumbar support is also available;
see pages 19-20.

Transpac II Owner’s Manual Page 12
Figure 3: Back pad and lumbar support.
Transpac II Air Cells
Interchangeable air cells for the Transpac II are available in ve styles. Each Dive
Rite air cell incorporates an air-tight inner bladder, surrounded by a heavy-duty
outer shell. Here are descriptions of the different air cells, and the roles each is
designed to fulll.
Figure 4: Travel Wings.
 Travel Wings (2071) Travel Wings are the most compact Transpac II air cell.
They can provide up to 30 pounds/14 kg of buoyancy and can accommodate
back-mounted single cylinders of up to 95 cubic feet/15 litres. An elastic outer
shell helps them maintain a streamlined shape. A 27-inch/69 cm low-pressure
inator hose is standard. Travel Wings are an ideal choice for divers who dive single
cylinders—or who want an additional, compact Transpac air cell for use solely with
singles (such as when travelling to a tropical resort destination).

Transpac II Owner’s Manual Page 13
Figure 5: Trek Wings.
 Trek Wings (2060) Trek Wings provide up to 40 pounds/18 kg of buoyancy. They
are best suited for use with single cylinders of any size, and with lightweight to
medium-weight double cylinders (“a shorter air cell for shorter cylinders”). Trek
Wings can accommodate up to two 83-cubic-foot/13 litre back-mounted cylinders.
Trek wings also incorporate a built-in gusset-control cord to help divers manage the
shape and lift capacity of the air cell (see page 15 for additional information on this
feature). A 27-inch/69 cm low-pressure inator hose is standard.
Trek Wings are a good choice for divers whose time under water is divided
between diving singles and lightweight doubles. They have also proven popular in
areas such as Mexico’s Yucatan Peninsula, where local cave divers want an air cell
that is well-matched in size to the double aluminum 80s which are popular in
this region, and which does not allow large pockets of air to slosh from side to
side, the way larger air cells tend to do. Further, Trek Wings are clearly “the” air
cell for side mounting.
Figure 6: Rec/Dual Rec Wings.

Transpac II Owner’s Manual Page 14
 Rec Wings (2074)/Dual Rec Wings (2075) Rec Wings provide up to 51
pounds/23 kg of buoyancy. They can be used with both single and double
cylinders. Rec Wings can accommodate up to two 104-cubic-foot/16 litre back-
mounted cylinders. Like Trek and Super Wings, Rec Wings also incorporate a
built-in gusset-control cord. A 27-inch/69cm low-pressure inator hose is standard.
Standard Rec Wings have a single internal bladder and ination hose. Dual
Rec Wings have a redundant bladder and ination hose. Rec Wings are a good
choice for divers who, while they may primarily use doubles, want to be able to
congure their air cell for use with single cylinders as well.
Figure 7: Classic Wings.
 Classic Wings (2030) Diving’s rst air cell designed specically for double
cylinders, Classic Wings provide up to 59 pounds/27+ kg of buoyancy. They are
designed for use with medium- to heavyweight doubles (Classic Wings should not
be used with single cylinders). These wings can accommodate up to two 104-cubic-
foot/16 litre back-mounted cylinders, and one 80-cubic-foot/11 litre stage bottle.
A 22-inch/56cm low-pressure inator hose is standard. Classic Wings are popular
among hard-core cave divers, who appreciate their simple, streamlined, “no frills”
design.

Transpac II Owner’s Manual Page 15
Figure 8: Super/SuperOne Wings.
 SuperOne Wings (2076)/Super Wings (2073) SuperOne Wings and standard
Super Wings provide from up to 84 pounds/38 kg of buoyancy, depending on
gusset-control cord tension. They can accommodate up to two 120-cubic-foot/19
litre back-mounted cylinders, and two 80-cubic-foot/11 litre stage bottles. (Super
Wings should not be used with single cylinders.) The wings incorporate a heavy-
duty outer bag and, in the case of the standard Super Wings, redundant inner
bladders with separate inators (SuperOne Wings have a single internal bladder).
One or two 22-inch/56cm low-pressure inator hoses are standard. Super Wings
are designed for technical divers who need or desire both exceptional buoyancy
and built-in redundancy.
More About Gusset-Control Cords The gusset-control cord found on Rec and
Super Wings fullls a variety of functions. Among them:
 When not inated, the cord helps compress the air cell to as small a prole as
possible. This reduces drag and helps protect air cells from damage.
 By tightening the cord, users can limit lift capacity to only that needed for a
particular application (example: diving single cylinders generally requires far less
buoyancy that doubles do). The benet is that reduced lift capacity also helps
reduce the likelihood of uncontrolled ascents.
 Tightening the Trek or Rec Wings’ gusset-control cord to its maximum limit helps
prevent the air cell from wrapping around the sides of single cylinders.
You can tighten or loosen the gusset control cord by adjusting the clips at each side of
the base of the air cell. When doing so, adjust both cords evenly.

Transpac II Owner’s Manual Page 16
Figure 9: The gusset-control cord found on Rec and Super Wings enables users to control
the overall shape and prole of these air cells.
Before diving with either Trek, Rec or Super Wings, you should spend time in
a controlled environment, such as a pool, experimenting with gusset control cord
settings. This will help you nd the setting that best ts your diving needs and your
overall equipment conguration.
Before using your Trek, Rec or Super Wings in open water or other,
more challenging environments, spend time in a controlled environ-
ment, such as a pool, practicing venting your wings in a variety of
positions. The inability to vent such a high-capacity air cell quickly
and efciently can lead to dangerous, uncontrolled ascents. Such
ascents can result in serious personal injury or death.

Transpac II Accessories
Weight Systems An integrated weight system is available for the Transpac II; Dive
Rite trim weights work with a wide variety of BCs and harnesses.
Figure 10: The Transpac II’s optional, integrated weight system, weight pocket inserts
and seven- and four-pound trim weights.
 Weight Pockets (2109) The Transpac II’s optional integrated weight system holds
up to 32 pound/15kg (actual capacity may vary, depending on the size and shape
of the weights used). Weight system components install easily on the Transpac II’s
2.0-inch/50mm waist strap.
The weight system’s pockets have a zipper on the top that divers can use to
add or remove weight in non-emergency situations. A ap at the bottom of the
pocket is held securely in place with a large Velcro® ap. In an emergency, pulling
on the ap’s large, color-coded tab opens the pocket.
 Weight Pouches (2110/2111) Two different types of weight pouches are available
for the Transpac II’s optional, integrated weight system. The model 2110 pouch
is designed for loose shot weight; model 2111 is designed for either normal block

Transpac II Owner’s Manual Page 18
weights or shot weight (model 2110 has a smaller zipper on top). Both come with
a convenient carrying handle.
 4- and 7-Pound Trim Weights (2150-4 and 2150-7) These can provide additional,
non removable ballast, as needed. Divers can use stainless quick links to mount
trim weights between the D-rings found along the side of the Transpac’s back piece.
Additionally, the seven-pound weights will t between the bolts of double cylinders
and the four-pound weights come with slots for 2.0-inch/50 mm webbing.
Pockets These attach to the Transpac II waist band or any other harness waist band
that uses 2.0-inch/50 mm webbing.

jon lines and similar size items. Available in Black, Blue, Red.
 Slate Pocket The Slate pocket (2016) is just the right size to hold a set of 2058
Executive Slate, plus has a built-in ring for keys. Available in Black.
Harness Accessories These accessories are designed to help you improve the
comfort and/or t of your BC harness, or to facilitate its use with a variety of
cylinders.

Transpac II Owner’s Manual Page 19
Figure 12: Stabilizing Plates.
 Stabilizing Plates (2084) Stabilizing plates allow the Transpac II harness and air
cells to be rmly secured to nearly any set of doubles that uses industry-standard
bands and bolts. They make attaching doubles quick and easy.
Figure 13: Sport Cummerbund.
 Sport Cummerbund (2104) Some divers prefer a cummerbund that completely
encircles the waist. For these divers, Dive Rite offers the “Sport” cummerbund.
The Sport Cummerbund is available as an after-market accessory, or may be special
ordered with the Transpac II.
Size Range
XS 24 in/60 cm to 28 in/70 cm
S 28 in/70 cm to 34 in/85 cm
M/L 32 in/80 cm to 40 in/100 cm
XL 38 in/95 cm and up

the “Tek” back pad and lumbar support are available as after-market accessories, or
may be special ordered with the Transpac II.
