Pro Single Cylinder BC System

The Halcyon Pro BC System is built for divers who demand maximum performance from the lightest, most advanced materials available. The Pro system delivers unmatched durability, strength, and comfort—all in a compact, travel-ready package.

At the heart of the system is a carbon fiber backplate, known for its incredible strength-to-weight ratio, corrosion resistance, and minimal bulk. It provides technical divers with robust support while significantly reducing total gear weight—perfect for both remote expeditions and air travel.

Lightweight Without Compromise.

The Pro Single Cylinder System begins with your choice of Eclipse or Era wing, a carbon fiber backplate with deluxe padding, stainless steel or aluminum hardware, and a carbon fiber single tank adapter with cam straps, packed in a Halcyon Traverse bag. Built for flexibility and a custom fit, this system combines premium materials with streamlined design. Use the Customize Tool to add ACB weight pockets, custom embroidery, or color upgrades for a setup that’s unmistakably yours.

Era Wing

From Evolution to Revolution Halcyon continually redefines industry standards with bold design and technical innovation. Building upon their 30 years of experience with each product, they proudly introduce a new generation of wings — engineered for optimal trim, comfort, and functionality, a new Era.

Halcyon Era – The Beginning of a New Standard The Era wing marks the dawn of a new age in single-tank buoyancy control. Designed from the ground up, it delivers unparalleled trim, comfort, and hose management for divers who demand the best. This can be done differently, and Halcyon is up for it.

Revolutionary Shape

A novel bladder and outer shell geometry distributes air more efficiently into the lower part of the wing, creating additional lift and facilitating the ease with which a diver can reach and maintain horizontal position. This trim position greatly reduces drag and diving effort, ensuring optimal performance and more relaxing dives.

Opti-Weight Pockets

Four zippered weight pockets are integrated into the wing’s outer shell, allowing for precise trim control when and where additional weight is needed. Each pocket holds 1kg (2.2 lbs). The bulk of a diver’s weight should be placed on the tank or torso, but these pockets are ideal for small adjustments in weight or trim/balance.

Smart Hose Routing

Dual hose openings — proven in the Halcyon Legend double-tank BC System — ensure clean, streamlined hose routing and optimal placement of accessories.

Compact Profile

A new low-profile elbow improves hose routing and fits tightly against the tank, providing more room for the diver’s head and reduced pressure on the corrugated hose fitting.

Carbon Fiber Backplate with Cinch™

Designed for divers who demand lightweight performance, this carbon fiber backplate is strong, corrosion-resistant, and travel-friendly.

Featuring the integrated, patented Halcyon Cinch™ system, it allows effortless harness adjustment—tighten or loosen your harness without removing the unit.

Travel-Ready and Effortlessly Adjustable

You can choose between aluminum or stainless steel hardware to match your weight and durability preferences. The backplate includes a built-in Cinch™, multiple slots, and finely milled edges, ensuring streamlined performance and long-term comfort.
