Beyond the choice of a MC buoyancy system, consider how you can streamline or improve your gear with the right dry suit accessory, attachment hardware, or stage or primary regulator hose kit.

Doing It Right diving involves a series of choices about how to optimize your gear selection to maximize your dive quality. The system can be as subtle as making sure that your manifold has a soft rubber knob to resist cracking or deforming in the event of a brush with an overhead object, or as obvious as making sure that your stage bottles are properly marked with their maximum operating depth.

Halcyon looks after the details so you can assemble a DIR rig as easily as possible. From mask to fin strap, we are the DIR dive system outfitting experts.

Halcyon Masks and Mask Strap
Made from the highest quality silicone components, Halcyon's single lens 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. The low-profile, dual-lens mask provides a comfortable fit for a wide variety of facial shapes.

Halcyon’s high quality neoprene mask strap fits any standard mask attachment, and provides an extra degree of comfort and stability.

Halcyon Diver's Notebook

Even the most casual of diver will appreciate the advantages of an underwater notebook over a plastic slate. Photographers have more room to make notes about locations and exposure settings, wreck divers more room for details about their discoveries.

Sized to fit in any BC or suit pocket, Halcyon's Diver's Notebook provides you with easy access to notes, tables, and accessories, in a cover made from the same ballistic nylon used in Halcyon's Eclipse and Explorer wings.

The Halcyon Diver’s Notebook includes a four-ring binder with replaceable underwater paper, clear pockets for both a compass and tables or fish ID charts, a Velcro bookmark, and elastic pencil holders.

Halcyon Gear Bag

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.

Halcyon Knife
Large, bulky knives are heavy and increase the risk of diver entanglement, particularly when attached to a diver's leg. Knives should be able to operate as tools and yet be small enough to stow out of the way until needed. The Halcyon titanium knife has 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 of your knife, Halcyon offers a custom designed knife pocket. This heavy nylon pouch is designed for mounting on the Halcyon Secure Harness waist strap where it severely limits the risk of entanglement from fishing line, kelp, or navigational guidelines.

Halcyon Fin Spring Heels

Halcyon's Spring Heels fulfill a common desire for a fin straps that is flexible, yet remains secure and resistant to breaking. By eliminating all the failures common to convoluted plastic connections, divers are freed from the risk and hassle of lost fins and broken straps. Designed to fit Jetfin-style rubber fins.

• Automatically adjust to the diver's feet
• Compensates for depth and compression of boot material
• Unbreakable strap provides an amazing degree of comfort and peace of mind
• Stainless steel main spring and safety cable
• Available in three sizes: medium (8" spring), large (10" spring) and extra-large (12" spring)

Proper hose length is an essential component of a safe and comfortable diving rig. Primary hoses that are too short present potentially uncomfortable and dangerous air-sharing situations, while excess hose decreases the streamlining of a rig and creates entanglement hazards. Halcyon'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 hoses are made in our High Springs facility and can be custom ordered to any length. Call us for additional details.

Single Tank Hose Kit:

Primary hose: 5'
Secondary hose: 22"
SPG hose: 24"

Double Tank Hose Kit:

Halcyon Manifolds

Our North American customers have already come to rely on the functional design and reliability of the Halcyon manifold. Halcyon's Manifold is available as either a rugged 300 bar or 200 bar DIN isolator manifold featuring shock absorbing ribbed rubber hand wheels and a true double barrel o-ring isolator seal. As a result of persistent requests from our international dealers, Halcyon is pleased to announce the introduction of a CE-approved M25 thread version of the Halcyon Manifold for our international divers.

Available for distribution to Halcyon dealers outside of the US, Canada, or Mexico, the new 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. Although many divers have requested a manifold without burst disks for use in the US, Halcyon will not distribute the M25 version of the manifold to any dealer in North America. Any mistaken attempt to install the M25 manifold on a set of tanks with 3/4-inch thread would prove to be extremely dangerous.

The domestic version of the Halcyon manifold fits tanks with 3/4-14 thread and includes 3500psi working pressure relief disks (PRD) required for use within the United States.

Thanks to a new casting utilized by both versions of the manifold, Halcyon's "H" logo is now sculpted into the body of each valve. All Halcyon manifolds are assembled with Viton o-rings and oxygen-compatible lubricants.

Single Tank Valves

Halcyon's new 300 bar and 200 bar Single Tank Valve provide the beefy construction that you will want for your stage and primary bottles. 200 bar yoke inserts are available, but do not ship with the valves. The Halcyon Single Tank Valve is also available in a M25, CE-approved version for the European market.

Halcyon Pressure Gauges

Introducing 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 can be ordered with either BAR (0-300) or PSI (0-5000) markings.

Halcyon Stage & Accessory Attachment Hardware

Stage Bottle Rigging Kit
The DIR Stage Bottle Kit is the model of efficiency and function. Proper rigging and marking of safety, stage, and decompression gas cylinders is a hallmark of the DIR philosophy. Our kit includes all you need to correctly set up your auxiliary cylinders for technical or overhead diving. The Kit is the same setup used for every stage, safety, and decompression gas cylinder utilized in the world record exploration of the caves of the Woodville Karst Plain.

Two 1" stainless bolt snaps
8.5" stainless tank band with stainless cylinder clamp
Six feet of heavy duty cord, with two feet of thick rubber hose protector
Thick tubular nylon covering for cylinder clamp to prevent exposure suit and bottle chafing
No metal neck rings; all attachment hardware can be cut free in case of entanglement or other emergency situations

Stage Bottle Marking Decals
Ensure proper marking of decompression, stage and safely bottles with GUE tank marking decals and gas analysis tape.
The MOD decals employ three inch black letters on a white background to ensure high visibility on any tank. Offered as a choice of Oxygen 20, 70, 120, 190, 240 or 300 MOD, all decals come in sets of two.

Accurate gas fills are facilitated using GUE gas analysis tape. The self adhesive tape affixes easily. When it's peeled off, it's peeled off-- no annoying, gummy paper residue!

Dry Suit Inflation Systems
If 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 kit. Our Octogrip Super Cam Buckle system securely holds the 14cf bottle to your single or double tank rig. A 1st stage regulator, OPV, and 24" inflator hose are provided with the complete kit. Inflation bottle mounting straps may be purchased separately.

New for 2003: mounting straps are now available for 6cf dry suit inflation bottles.
