Delayed SMB from AP Valves with built in self-inflating cylinder mechanism - British Standard cylinder included.
Operation is simple, just unfurl the SMB, crack the cylinder and release to the surface.
The fully sealed system is inflated by the compressed air in the cylinder to ensure full inflation from any depth - even those tricky shallow ones. Complete with over inflation valves for safety.
Inflation cylinder can be quickly and easily replenished from your main cylinder ready for re-deployment on your next dive.
