Having a spare as a technical diver is routine. This 12-pack of Retractor Bands can get you out of a jam if you find a problem with the ones attached to your BCD. The bands are an important component of your buoyancy Control Devise. ELIMINATION OF AIR SHIFT:
The OMS elastomeric bands evenly compress the BC, eliminating the massive air shift associated with non-banded BCs that typically occur when changing body plane. LOW DRAG / LOW SNAG:
The OMS bands typically retract the BC to a width less than the diver's shoulders, greatly reducing Drag and Snag potential. TRIM ADJUSTABILITY:
By adding or eliminating bands in different parts of the BC, the diver can adjust: a) lateral trim to compensatefor stage bottles, cameras, etc. b) Horizontal trim, e.g. head up, down or level.
