Why Choose the Halcyon Eclipse Wing System?
The Halcyon Eclipse Wing System is widely regarded as one of the finest single-cylinder buoyancy systems available. Unlike traditional jacket-style BCDs, the Eclipse Wing positions buoyancy behind the diver, helping maintain a balanced, horizontal trim while reducing drag and improving efficiency throughout the dive.
