The Halcyon Infinity Wing System is not your typical buoyancy compensator. In fact, it establishes a new standard in single-tank diving, offering the unparalleled performance of a back mounted harness and the easy adjustability of a jacket BC.

Try Before you buy - HalcyonThe Infinity BC features Halcyon’s immensely popular Eclipse wing - a long, narrow profile which supports a diver’s tank along his or her entire length, preventing unnecessary drag and minimizing in-water effort.

The Infinity's most distinguished feature is the novel harness adjustment known as the Cinch Quick Adjust Harness, which redefines what it means to dive a backplate, providing unparalleled comfort and stability in a system with infinite adjustability.

Halcyon Infinity MC SystemUnlike other designs the Cinch adjustments eliminates all quick release buckles and dangling webbing. The industry-first innovation marries the stability and streamlining of the backplate with the comfort and flexibility of a recreational BCD.

Halcyon's long, narrow wing design supports the divers tank along its entire length, preventing unnecessary drag and minimising effort.

  • Infinite adjustability in the blink of an eye
  • Snug, stable fit with easy removal
  • Easily adjustable while in or out of water
  • Easily convertible for suits of varying thickness
  • Ships fully assembled
  • Lifetime warranty on inner bladder seams


  • Halcyon Eclipse Wing (20lbs, 30lbs or 40lbs)
  • 22" Inflator hose
  • Halcyon Ali or SS Backplate
  • Adjustable Cinch Harness
  • Halcyon Single Tank Adapter with SS buckles
  • Halcyon Deluxe Shoulder Pads
  • Halcyon Deluxe Backplate Pad

Halcyon Eclipse 30 WingThe Halcyon Eclipse is a low profile, exploration-grade wing that leaves all other single tank designs in its shadow. Another example of Halcyon taking the game to the next level.

The Eclipse wings have a long and narrow profile to support the diver's tank along his or her entire length, preventing unnecessary drag and minimizing effort. A circular zipper around the inside of the wing allows for easy inspection.

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. 

A drainage system allows water to drain rapidly from the outer cover to minimize excess weight.  

An inflator elbow strain relief constructed from two-inch nylon webbing minimizes wear on this.

Halcyon inner bladders are RF welded with a lifetime warranty on all seams.

  • Outer shell 1680-denier ballistic nylon
  • Inner bladder 400-denier Nylon
  • Available in 20, 30 and 40 lbs lift capacities. 

Which wing size?

The Halcyon Eclipse wing comes in 20, 30 and 40lbs lift capacity and the amount of lift required by a diver depends on his/her kit configuration. Stretched out flat the Eclipse 30 measures 67cm x 46cm compared to the Eclipse 40 which is 70cm x 50cm.

The 30lbs wing is more suitable for a lighter profile diving rig such as a single 12L steel cylinder whereas the 40lbs is ideal for divers who want that "extra bit" of lift for emergency assistance or to carry heavier cylinder setups like a 15L cylinder.


Now divers can easily adjust the fit of their plate in or out of the water a simple push or pull is all it takes.

Halcyon backplateThe Cinch harness redefines what it means to dive a backplate, building upon a platform of simplicity while providing unprecedented security and ease of adjustment. Halcyon developed the Cinch to save divers time and effort while sizing, fine-tuning and resizing your diving harness. Now you can change suits or divers and adjust the Cinch in a flash; all this without compromising the harness integrity or our trademark, continuous piece of webbing.

Adjustments to the Halcyon Cinch occur by simply sliding the harness through a unique, patent pending assembly.

If you need a quick way to get out of your dive system; if you regularly change the thickness of your diving suit; or if you train new students in Halcyon rental equipment, this new invention will change the way you dive.


As with most Halcyon products, an immense amount of behind-the-scenes work is required to create a plate we are proud to sell. Halcyon backplates have been refined over the years to provide the highest-quality finish and materials available.

Small details like the unique bends near the bottom of the plate create an ergonomic curve, increasing diver comfort. Meanwhile the precise fabrication process ensures the quality you have come to expect from Halcyon.

Each Halcyon backplate is cut from the highest quality stainless steel or har-coated aluminium and sophisticated CNC machines mill every edge; this detailed process eliminates the sharp edges common with competitors’ plates.

When you use a Halcyon backplate you know its different from the others with machine polishing  augmented by individual handwork that stands out, perfecting both form and function.

  • Constructed from high-grade, polished Stainless Steel or hard-coat Aluminum
  • Carefully milled surfaces eliminate sharp edges

  • Utility holes allow mating with Storage Pak to stow a variety of lift devices or SMB
  • Stainless Steel weight: 2.7kg
  • Aluminum weight: 0.9kg

What backplate to use?

While not set in stone, aluminium backplates are generally preferred by traveling or wet suit divers as they are lighter than their stainless steel counterparts. The popular backplate for dry suit diving is the stainless steel, where the additional weight is a benefit (spreading out the weight needed to compensate for buoyancy while taking it off the diver's waist).

Halcyon Single Tank AdapterBoth backplates are based on the same Halcyon design and are compatible with the Halcyon Cinch Adjustable Harness. Most UK divers who use dry suits prefer the SS backplate.


Halcyon's Single Tank Adaptor is used to mount the wing and backplate to a single cylinder.

The standard single tank adapter can be upgraded to a Halcyon Weighted Single Tank Adapter. The central weight can be removed if not required making it back to a standard adapter.


Halcyon deluxe padsHalcyon Deluxe shoulder pads and a backplate pad offers ultimate comfort while diving in thinner exposure suits.

The deluxe shoulder pads allow the diver to customize d-ring position by way of movable velcro tabs.

The backplate pad also features a BC Storage Pocket allowing the diver to carry a surface marker or lift bag in a streamlined position.

Adjustable Shoulder Pads feature movable Velcro tabs for a custom fit around shoulder D-ring and harness accessories (e.g. Scout light).

Backplate pad features an integrated storage pocket to carry lift devices for the ultimate in comfort and convenience.


Halcyon ACB Weight PocketsHalcyon ACB (Active Control Ballast) integrated weight pockets are an ideal solution for divers seeking releasable weight for their Halcyon BC system.

This patented Halcyon design is simple and effective; when complemented by our fixed and removable ballast options, these pockets fine tune system weighting while supporting stability and diving comfort.

  • 10-lb. ACB System (5 lbs/2.3 kg per side)
  • Vertical orientation consumes less space
  • Simple tri-glide connection secures the ACB on the Harness waist band
  • Allows mounting of a primary light behind the ACB pocket
  • Side release buckle prevents accidental weight loss but can be quickly released

  • Removable weight pouch features an easy-carry handle
