The Halcyon Quick-adjust harness sets a new standard in recreational and
technical BC systems. The Cinch (patent pending) can be used with
single or double tanks and allows easy harness adjustability while
avoiding “quick-release” buckles and dangling webbing.  Simply push or
pull the webbing and your size adjustment is complete.  This quick,
easy-fit system allows divers to size a snug harness without
compromising easy removability. It is also ideal for student training
and rental departments, or for divers that wear suits of varying
thickness. The system is easily adjustable in or out of the water,
making it ideal for convenient, in-water equipment removal. The Cinch is
also very effective during emergency situations.
