Dive Alert uses a small amount of air from your scuba tank to make a piercingly loud sound. People have been able to hear a Dive Alert one mile away from a diver in need. In conditions where visibility is limited, a Dive Alert can be a life saver.
HOW IT WORKS
The Dive Alert uses chrome-plated brass couplings to attach to your power inflator. The activator button engages a chrome-plated brass actuator valve stem causing a small amount of air to rush by a stainless steel diaphragm, emitting a piercingly loud sound from the injection-molded thermoplastic body.
