Halcyon DIR Dive Systems
“Doing It Right” diving is a philosophical approach to scuba diving, holistic in conception, which elaborates the essential elements of
sound diving practice. DIR promotes rational choices with respect to dive teams, dive preparation, and equipment configuration as a
means toward greater safety and more fun.
Halcyon has been at the forefront of DIR since its inception; as internationally-active explorers, our staff develops, builds, and relies
on the very same equipment to keep us safe in some of the world’s most inhospitable locations. From deep wreck and overhead
exploration to recreational reef dives, DIR and Halcyon are revolutionizing diving while striving to make it safer and more enjoyable.
Doing It Right is in Halcyon’s DNA

Reduced Drag + Proper Balance = Better Diving!
Bulky BCs draped with padding and fitted with a one-size-fitsall air cell may seem good in a showroom, but in the water they
produce unnecessary drag, requiring exponentially more effort.
Halcyon's Multifunction Compensator™ gives you the
advantage to get the most out of every dive. From your first
check-out dive to your mastery of Trimix diving, Halcyon’s MC
System™ can be fine-tuned to fit any diver and any conceivable
dive.
No other system in the world provides better balance or less drag.

Diving the Halcyon Eclipse Wing in Bimini/Dickie Walls
Merely doubling the area of one’s BC results in a force of
resistance that is four times as great and requires nearly 16
times more energy to move through the water. This factor
means that small improvements in your equipment's profile can
massively reduce the energy you expend, ultimately resulting in
less effort and more fun.
Halcyon’s range of carefully designed BCs can each be mated
to our infinitely adjustable Secure Harness System, providing
divers with streamlined buoyancy across a range of single and
double tank diving environments.
A wide array of weighting options complement the Halcyon
diver’s ability to tune their gear’s configuration. Choose from
a stainless or aluminum backplate and add trim weights, ACB
weight pockets, or V-weight to perfectly balance your diving
configuration.

Diving the Halcyon Eclipse Wing in Bimini/Dickie Walls
Eclipse & Pioneer
Buoyancy
Compensators
Halcyon’s reputation is built on its dedication to innovation and
quality. Divers from around the world turn to us for their gear
because of a simple formula that we’ve always followed:
Dive, design, prototype, dive, refine, dive, build, dive.
Repeat as necessary.
Our latest creation? The Halcyon Eclipse wing. Think of it as
a Pioneer wing gone to the gym. Halcyon builds the Eclipse’s
outer shell from 1680-denier ballistic nylon. We then add an inner
bladder constructed from the same puncture-resistant 400denier Nylon inner-bladder material used in the Explorer. In other
words, the Eclipse is a low profile, exploration-grade wing that
leaves all other single tank designs in its shadow. Streamlined.
Ruggedized. Another example of Halcyon taking the game to the
next level.
Halcyon’s original Pioneer shook up recreational diving by
promoting the benefits of a streamlined single-tank, circularbladder wing. This circular design simplifies removal of gas
from the rear OPV and creates greater in-water stability. Pioneer
series wings utilize a welded shell design.
The Eclipse wings share the Pioneer’s long, narrow, wing
profile to support the diver’s tank along his or her entire length,
preventing unnecessary drag and minimizing effort.

Florida/Anthony Rue • Bimini/Dickie Walls
A choice of lift capacities helps to maximize comfort and streamlining while accounting for various buoyancy
requirements that result from differences in tank size, exposure protection, or equipment requirements.
Eclipse wings require a single tank adapter to mount with your Secure Harness backplate system. Pioneer
wings continue to utilize Halcyon’s adapter-free design and only require a set of Halcyon cam straps for
mounting.
Eclipse wings are available in 30 and 40 lbs lift capacities.
Pioneer wings are available in 27, 36, and 45 lbs lift capacities.
Explorer Buoyancy Compensators
The Explorer double tank wings are available in 40 lbs, 55 lbs, and 70 lbs lift capacities to accommodate a
wide range of tank sizes, exposure protection, and equipment requirements.
•1680-denier ballistic nylon outer shell for increased abrasion resistance
•Heavy-duty zipper with a three-inch wide barrier to prevent zipper chafe on the inner bladder
•“Trapdoor” drainage system allows water to drain rapidly from the outer cover to reduce excess weight and diver effort reboarding the dive boat
•Strain relief on corrugated hose and precision location of elbow connection reduce stress on this vital area
•400 denier nylon bladder maximizes durability with puncture resistance and greater flexibility
The 40 lbs Explorer wing provides a minimalist approach to buoyancy where double
aluminum 80s and a wetsuit are the rig of choice. The widely popular 55 lbs Explorer wing
is ideally suited for situations requiring additional lift, such as when diving with heavy
double steel tanks. The 70 lbs Explorer wing is designed specifically for heavier steel
tanks and multiple stages where divers are unable to attain proper lift from the Explorer
55 lbs wing.
Halcyon’s Eclipse and Explorer wings carry CE type approved for sale in all of the
European Community.
All Halcyon wings now come with our newly designed precision-flow inflator. The internal
components and buttons are 316 stainless steel. Halcyon’s inflator provides a controlled
low-volume air flow to allow the diver to fine tune their buoyancy and resist freezeing in
extremely cold conditions. The Halcyon inflator is another Halcyon innovation that will
only be found on Eclipse, Pioneer, and Explorer wings.

Trim Weighting Kit
The Halcyon Trim Weighting Kit promotes heads-up surface airway
protection by counteracting the positive tendency of buoyant
cylinders.
•Shifting weight from a diver's waist toward their center, such
as with a stainless Halcyon Backplate or trim weight system,
facilitates horizontal diver trim and reduces drag
•Popular with instructors who are sensitive to the complete loss
of a diver's weight and who resist integrated weights that prevent
practicing emergency weight removal

Alternate Lift Devices
Lift devices are essential tools for all diving activities ranging from recreational drift and
salvage diving to signaling and emergency flotation. When combined with the ease of storage
provided by the MC Storage Pak, the flexible manner in which a variety of lift devices can be
integrated into the Halcyon MC system emphasizes diver safety and comfort.
Halcyon's Supra closed and semi-closed circuit lift bags, Surf Shuttle™, and/or Diver’s Alert
Markers belong on every drift, shore, or wreck dive. The Diver’s Life Raft™ is a vital addition
to anyone’s kit when presented with the possiblity of separation from the boat or being swept
away from shore.

Lift Bags
Halcyon Semi-Closed Circuit 60 lbs Lift Bag
Halcyon’s SCC 60 was designed to allow for easy lift inflation
when convenient access to a low-pressure inflation hose isn’t
an option. Designed to be filled by the diver’s second stage
regulator, the SCC 60 combines the ease of inflation of a
traditional bell bottomed bag but with a specially designed fluted
entrance way to greatly reduce the risk of gas escaping. The
SCC 60 is also fitted with an over pressure release valve to dial
in precise amounts of lift and to prevent damage caused by overinflation.
Halcyon Closed Circuit 80 & 185lb. Lift Bags
Halcyon’s closed circuit lift bags were designed to provide
a reliable source of redundant buoyancy at depth or on the
surface. The closed circuit bags can be inflated with a low
pressure inflation hose through the patented No-Loc connector.
Alternatively they can be orally inflated when necessary.
SCC 60
•Semi-closed circuit design, perfect for wet suit divers
•Over-pressure valve allows for lift modulation during salvage lift
operations
•Baffled inflation chamber prevents accidental dumping in rough
conditions
CC 80 & 185
•The industry standard for technical applications where precise
control over lift and surface floatation are essential
•Closed circuit design ensures that the object of a difficult search
will reach the surface without the risk of inadvertently dumping or
losing buoyancy
•Attach to any low pressure inflator hose using a No-Loc
connector or orally inflate

Markers & Rafts
Diver Alert Markers
Halcyon's series of Diver Alert Markers provide maximum
visibility and redundant flotation at the surface. Open water
divers should always carry a marker buoy they can deploy in
the event of separation from buddy, primary group, or boat.
Small Alert Marker: 3.3' long, 6 lbs lift
Big Alert Marker: 4.5' long, 40 lbs lift
Super Alert Marker: 6' long, 52 lbs lift
Big and Super Alert Markers both come with Coast
Guard approved SOLAS reflective tape across the top
for improved visibility. Halcyon Dive Alert Markers feature
closed-circuit (one-way valve) construction. All markers are
small enough when deflated to fit in a Halcyon thigh pocket
or MC Storage Pak.
Halcyon Surf Shuttle
The Surf Shuttle provides an essential margin of safety for
the diver facing a long wait at the surface prior to boat
pickup, or even a long swim to shore. Essential gear for any
diver who enjoys drift diving in a ripping current.
•30 lbs lift capacity
•Perfect for divemasters or instructors working with novice
divers
•Can be deployed with a spool to mark position
•Special message holder allows divers to communicate with
surface crews
•Stores neatly in the MC Storage Pak or thigh pocket

Once thought the domain of cave divers, Halcyon reels and spools have become a common tool for
many divers. From their use as cave and wreck penetration lines to their place in deploying lift bags
it is becoming increasingly rare to find a diver without such basic safety equipment.
Defender Spools
For any diving application where you will use less than 150
feet of line, the spool provides rapid, jam-free deployment and
retrieval. Defender™ spools are the DIR choice for deploying
lift devices in the open water or for use as jump/gap or safety
spools while cave diving.
•Made from solid Delrin for crush-proof durability
Pathfinder Reels
The Pathfinder™ series of line reels satisfies the demanding requirements of exploration as well as
the day-to-day needs of recreational divers. The unique ambidextrous side handle is machined from
a solid piece of aluminum and fits closely to the spool, limiting the possibility of entanglement. All
Pathfinder reels come standard with cold water lock-down screw to ease operation when a diver is
wearing neoprene or dry gloves. Pathfinder reels come with #24 braded nylon line in lengths of 400,
800, and 1200 feet/122, 244, and 366 meters.

•6.7 lbs scrubber provides approximately 8 hours of usage; optional “half-pack” spacer
to reduce capacity to 4 lbs available as an option
•8:1 ratio provides substantial gas extension: Double 40ft3 tanks provide roughly 640ft3 of usable gas
•Patent pending water removal system automatically vents excess water from loop
•Semi-closed operation eliminates the risk of unit-induced oxygen toxicity
•Unique design allows full access to on-board gas supply in either semi-closed circuit or open
circuit modes for maximum safety and flexibility
The Halcyon rebreather supplies breathing gas as required by the diver’s respiratory rate, providing less oxygen variation and better
predictability. Gas replenishment is mechanically triggered by the diver’s breathing cycle so that a compromise in supply is obvious and
immediate. Full advantage of advanced breathing gases is maximized by the significant reduction in oxygen variation common in all other
semi-closed designs.

Helios & Proteus
Lighting Systems
Halcyon’s Helios™ and Proteus™ lighting systems are widely
regarded as the standard for underwater illumination. Recreational
and technical divers, leading-edge explorers, and film industry
producers all depend on Halcyon for their primary light systems.
Conventional Halcyon lighting systems utilize a filament similar to
that found in a conventional light bulb and have a yellow cast and
less water column penetration than HID.
HID technology replaces the filament of a conventional light bulb
with a capsule of gas in which two closely spaced electrodes are
supplied the power to emit light. This unique system produces
substantially more light (at daylight color temperature) while
consuming significantly less power.
18 watt HID Lighthead
Halcyon's workhorse light, the 18 watt HID, allows full adjustability
and easy bulb changes in a conventional test tube style design.
Light output is similar to a 75 watt halogen light at a fraction of the
power consumption.
10 watt HID Lighthead
Where innovation meets practicality. Halcyon's fully closed light
head (patent pending) provides divers with a nearly indestructible
light head that is able to be adjusted from a laser-like beam to a
diffuse soft light with the mere twist of a dial.

Gator Wraps
Halcyon Gator Wraps provide dry suit divers with extra comfort, increased safety, and reduced
drag by limiting airflow to your feet. Rugged Cordura construction and double Velcro® closure
make the Halcyon Gators as tough as they are functional. Now you can gain the same high
performance advantage as leading exploration divers. From cave to wreck and everything in
betwen, technical divers will find Gator Wraps a welcome alternative to cumbersome ankle weights
and bulky dry suit legs.
Available in adjustable 12-inch , 14-inch, and 16-inch calf sizes;
Gator Wraps stretch to accommodate most divers.
P-Valves
Many male divers credit the Halcyon P-Valve among their best equipment purchases. With the
Halcyon P-Valve divers can easily avoid the health and DCS risk associated with poor hydration
while protecting the sanctity of their diving suit. Whether you are interested in a short, comfortable
dive or face long decompression obligations, the Halcyon P-Valve can provide a new level of
diving comfort.
Balanced
The Halcyon balanced system increases comfort and confidence through the addition of a
chamber to equalize the pressure between the valve system and the outside water. One check
valve prevents water from entering the catheter system and the other allows ambient suit air to
enter the assembly, equalizing the pressure. This unit also contains a P-through screw that can
function as a back-up to the first check valve.
Unbalanced
The Halcyon unbalanced valve is made of the same high-quality components as the balanced
valve, but does not include the balance chamber. This means that water can enter the tubing/
condom assembly when the P-through screw is opened. The unbalanced valve’s low profile makes
this unit ideal for wet suit use.
All Halcyon P-Valves come with crush-proof tubing to prevent unfortunate kinks during a
dive and install in minutes with a minimum of tools. Easy to use external catheters are also
available through your Halcyon dealer.
