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.
