The Halcyon Pro Double Cylinder BC System is the ultimate twin-set platform for technical divers pushing boundaries—whether you're in a cave system, exploring wrecks, or preparing for advanced expedition diving.

At its core is Halcyon’s carbon fiber backplate with integrated Cinch™, a premium combination offering exceptional strength, corrosion resistance, and ultra-light weight. Despite its minimalist weight profile, carbon fiber delivers the rigid stability technical divers rely on.
