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-fits-

all 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.

Discovery Passage, Campbell River BC/Sonya Tittle

4 5

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.

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 400-

denier 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, circular-

bladder 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.

Eclipse & Pioneer Buoyancy Compensators

Diving the Halcyon Eclipse Wing in 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 CompensatorsThe 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.

release mechanism and weight handle

Halcyon’s ACB Systems are protected by US Patent #6527480.

Halcyon’s Trim Weighting Kit is protected by US Patents #5855454

and 6530725b1.

Behind the Backplate Weighting

Halcyon’s V-Weight mounts between manifolded cylinders to

provide precise weighting, allowing you to carry the minimum

removable weight to facilitate a swimming ascent. V-Weights are

vailable in 11 lbs and 8 lbs sizes. Halcyon’s Weighted Single Tank

Adapter provides six pounds of non-releasable ballast between

you and your single cylinder rig. The weighted STA works with all

Halcyon backplate and single tank wing designs.

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

•Up to five pounds of weight can be attached to your tank with

each streamlined trim weight pocket

Bimini/Dickie Walls • Fiji Reef/Sonya Tittle8 9

Alternate Lift DevicesLift 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.

10 11

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 over-

inflation.

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

•Redundant flotation at any depth

•Similar to Navy pilot life raft on the surface

•Inflatable floor

•Optional storage pouch for divers not utilizing Halcyon’s

MC Storage Pak

•Optimal for cold water and where divers might be stranded

far from shore

Markers & RaftsDiver 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

Guidelines

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

•Stainless steel, double-ended bolt snap attachment hardware

•Available with 75’/23 m, 100’/30 m, and 150’/46 m of #24

braded nylon line

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.

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.

Halcyon RB80 Rebreather

There is nothing like an idea

who's time has come

Divers from the icy waters of the Antarctic

to the caves of the Woodville Karst Plain rely

on Halcyon for reliable, safe, and intuitive

rebreather diving.

All this in a package smaller than an aluminum 80

•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.

New stainless steel tank mounting frame, for use with a wide range of tank diameters, including 8”/203mm, 7.25”/184mm, 7”/178mm, 5.5”/

140mm, and 5.25”/133mm cylinders.

Halcyon’s extremely intuitive and reliable

operating system eliminates distractions

and reduces failures that can mean

the difference between a mission’s

success or failure. The simplicity that

gives the Halcyon RB80™ its advantage

for exploration is just as important for

less demanding environments where

divers may become distracted by their

surroundings, by the pictures they are

taking, or by the needs of a dive buddy.

Helios & ProteusLighting SystemsHalcyon’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

P-Valves

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.

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.

22 23

Dry Suit Inflation PocketsIf your idea of a good dive includes cold water, long bottom

times, or helium-based mixes, you will understand the necessity

of Halcyon's dry suit inflation mounting kits. Our Octogrip Super

Cam buckle system securely holds the 14ft3 bottle to your single

or double tank rig by attaching to a tank. Halcyon’s smaller 6ft3

bottle mounting straps allows open water divers to secure a

smaller inflation bottle directly to their Halcyon backplate. Our

compact 1st stage Over Pressure Relief Valve provides and added

measure of safety to your dry suit inflation kit.

Halcyon Pockets add a needed level of utility to your wet or dry

suit. Preferred DIR placement calls for the use of a bellowed

pocket on the left thigh, with plenty of room for a spare mask,

double enders, and a few Defender spools. The flat pocket is

to be mounted on the right thigh and is just the proper size for

holding Wet Notes and decompression tables. Both are available

from Halcyon to be mounted on your suit with simple tools and

adhesives.

Mask

A simple utility bag to store dive, boat, or travel gear, generously sized at 30

inches long by 12 inches in diameter, with a large exterior Velcro pocket. Tough

Textilene withstands the abuse of exploration travel, yet allows plenty of air

circulation. Black, 420-denier Nylon bottom keeps sand out of the bag and off

your gear. Semi rigid handles are easy to grab and comfortable to carry on the

boat, plane, and/or pack mule.

Made from the highest quality silicone components, the Halcyon dive mask

is simple, yet rugged in design. The black frame and soft-fitting silicone skirt

surrounds a single lens, creating a low volume mask for easy clearing and

minimum drag.

Knife

Gear Bag

Dive knives should be large enough to be functional as a tool and yet be small

enough to stow out of the way until needed. The Halcyon stainless steel knife has

a blunt tip, line cutter, and serrated edge along one side of the three-inch blade,

with a total length of six inches. For convenient and proper storage, the knife

includes a custom designed knife pocket. This heavy nylon pocket mounts on the

Halcyon Secure Harness waist strap where it is easily within reach while remaining

less likely to become entangled in fishing line, kelp, or navigational guidelines.

Submersible Pressure GaugeIntroducing the Halcyon DIR Pressure Gauge. It's just what you would expect in a DIR SPG: low tech,

reliable, and accurate. The classic heavy-duty brass housing and tempered glass lens will stand up to

any environment, while the easy-to-read gauge face is available with either BAR (0-300) or PSI (0-5000)

markings.

Valves & Tank BandsHalcyon’s manifolds and single tanks valves incorporate all of the truly essential elements of valve design

into one package. The rugged 300 BAR DIN isolator manifold features shock absorbing ribbed rubber hand

wheels with stainless steel inserts and a true double barrel O-ring isolator seal. The domestic version of the

Halcyon manifold fits tanks with 3/4-14 thread and includes 3300 PSI pressure relief disks (PRD) required

for use within the United States.

Available for distribution to Halcyon dealers outside North America, the metric variation of the manifold

features M25 (metric) tank neck threads and does not incorporate a pressure relief disk (PRD). The

Halcyon M25-thread manifold is stamped with CE approval.

Halcyon designed its 300 BAR DIN single tank valve from the ground-up to satisfy our own diving

requirements. The valve is fitted with the same rubber hand wheels with stainless inserts as our mainifold.

All Halcyon valves are assembled with Viton O-rings and oxygen-compatible lubricants.

Compliment your doubles with bands of uncompromising quality. These bands are available in three sizes to

accommodate aluminum 80s, steel 95s, 104s, 120s, and Pressed Steel’s new E-series steel cylinders. Halcyon

has eliminated the difficulties and uncertainty attributed to low quality bands that are fitted with cheap threaded

rod and provid discriminating divers with easy access to the industry’s highest quality bands.

Stage KitsThe Halcyon Stage Kit includes our premium stainless

steel attachment hardware to provide ample security and

maneuverability at exactly the right points, while avoiding

ill-conceived metal-to-metal contacts. The kit includes nylon

tube webbing to protect divers’ water-softened skin and

to insulate a diver’s exposure suit from accidental cuts or

abrasions. Braided nylon line provides a hardy connection

between diver and bottle, yet still allows the stage to be cut

free should the need arise. Each kit comes with a choice of

MOD decal.

Hoses & Hose KitsHalcyon’s DIR Hose Kit provides a diver with the hoses

necessary to complete a single or double tank rig or stage

bottle, including the primary, secondary, and SPG hoses in

the correct lengths for each. Halcyon can cut custom hoses

to fit any application; contact your Halcyon dealer for more

information.

Marking DecalsProper marking of decompression, stage, and safety bottles

is a core requirement of DIR diving. GUE tank marking

decals and gas analysis tape takes the guesswork out of

mixed gas and decompression diving.

The MOD decals employ three inch black letters on a

reflective background to ensure high visibility on any tank.

Offered as a choice of Oxygen 20, 70, 120, 190, 240 or 300

MOD or metric markings of Oxygen 6, 21, 36, 57, 72, 90

MOD, all decals come in sets of two. Accurate gas fills are

facilitated using GUE gas analysis tape. The self adhesive

tape affixes easily and peels off without leaving annoying,

gummy paper residue.
