Halcyon

Halcyon Standard Single Cylinder BC System, Aluminum Backplate

Halcyon's entry point into its modular backplate-and-wing line, pairing an aluminum backplate with the Eclipse or Era wing.

Wing / backplate

Modular harness and wing, the standard technical-diving setup. Expect to configure backplate, wing, and harness separately rather than buying a fixed jacket.

"Lift capacity" is the manufacturer-rated buoyancy the wing/bladder can provide at the surface. Match it to your exposure suit, tank, and weighting, not the biggest number available.

Pros
  • Choice of Eclipse (20/30/40 lb) or Era (30/40 lb) wing lets divers match lift to their exposure suit and cylinder
  • Infinitely adjustable Secure Harness, with an optional Cinch Quick-Adjust upgrade for faster donning and doffing
  • Ships assembled in a Halcyon Traverse carry bag, aimed at travel-minded divers
Cons
  • No integrated weight system; divers need a separate weight belt or backplate-mounted weight
  • Halcyon doesn't publish a fixed price, D-ring count, or system weight; final cost depends on the wing, size, and upgrade options chosen through their configurator
Diver community sentiment
Mixed opinions

Scubaboard discussions show real ambivalence about Halcyon's single-cylinder systems. Praise centers on bladder build quality, packability, an adjustable/modular harness, and comfort once properly dialed in, several divers report forgetting they're wearing it after a break-in period. Recurring complaints include stainless inflator mechanisms leaking or sticking even after service, "cheap and weak" harness buckles, integrated weight pockets that loosen, and tank-strap slot positioning that can force the strap too high with smaller cylinders. A separate strand of criticism is about value: several posters argue Halcyon's price premium over comparable rigs (DSS, OMS, generic AL plates) is largely a "logo tax."

Summarized from public forum discussion (Scubaboard, Reddit, and similar), not a survey we ran ourselves. See the linked threads for the original conversations.

The Standard Single Cylinder BC System is Halcyon’s baseline modular backplate-and-wing package, built around an aluminum backplate, a Secure Harness, and a choice of Eclipse or Era wing. It’s the same core Halcyon platform as the Pro system but without the carbon fiber backplate or deluxe padding, aimed at divers who want Halcyon’s modular, no-nonsense harness at a lower entry price. Like the rest of Halcyon’s single-cylinder line, it ships assembled with an MC Storage Pak, crotch strap, and stainless steel tank adapter, packed in a Traverse bag.
