4 5 Diving the Halcyon Eclipse Wing in Bimini/Dickie Walls Merely doubling the area of one’s BC results in a 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 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 , 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 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 ’s tank along his or her entire length, preventing unnecessary drag and minimizing effort.

Florida/Anthony Rue • Bimini/Dickie Walls 6 7 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 •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 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.

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 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- 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. SCC 60 Alternatively they can be orally inflated when necessary.

Halcyon’s extremely intuitive and reliable operating system eliminates distractions and reduces failures that can mean There is nothing like an idea the difference between a mission’s who's time has come success or failure. The simplicity that Divers from the icy waters of the Antarctic gives the Halcyon RB80™ its advantage to the caves of the Woodville Karst Plain rely for exploration is just as important for on Halcyon for reliable, safe, and intuitive 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.

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 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 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.

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 ) 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.
