This version of the Dive Alert can be used both on the surface as underwater. DiveAlert is a specially designed, small, light weight air horn that uses quick-connect / disconnect hose couplings to become an integrated part of your power inflator and buoyancy compensator. Installation is easy and only takes a moment.
DiveAlert uses a small amount of air from your SCUBA tank to make a piercingly loud sound. People have been able to hear a DiveAlert 1.6km away from a diver in need. In conditions where visibility is limited, a DiveAlert can be a life saver. DiveAlert does not require any modification to your equipment, and it does not interfere with the normal operation of your equipment.
