Halcyon Evolve Double System BC

The Halcyon Evolve maintains a novel, industry first-design; this unique circular wing provides unprecedented control, allowing divers to easily fine tune their buoyancy regardless of diving position. Individuals diving in all environments will appreciate the ease of adjustment and the streamlined, cylinder hugging design of the Evolve; two different lift capacities allow easy pairing with small doubles or large, heavy steel tanks. Whether swimming or scootering, the Evolve cuts through the water with less drag and greater efficiency, encouraging less effort and more diving enjoyment.
