DiveAlertPLUS: a Dual Function Surface / Subsurface Signalling Device
DiveAlertPLUS is a specially designed, small, lightweight pneumatic signalling device that uses quick-connect/disconnect hose couplings to become an integrated part of your power inflator.
It uses a small amount of air from your SCUBA tank to make a piercingly loud sound in air or water. It can be heard a mile away from where the diver in need is above water.
How it works
The DiveAlertPLUS uses chrome-plated brass couplings to attach to your power inflator. Squeezing the device engages the actuator valve stem causing a small amount of air to flutter a stainless steel diaphragm emitting a piercingly loud sound. The subsurface/underwater signal is produced by a percussion “buzzing” noise made by a piston hitting a stainless steel diaphragm much like a drum.
