The Dive Alert PLUS is a specially designed, small, light weight pneumatic signaling device that uses quick connect/disconnect hose couplings to become an integrated part of your power inflator. Installation is easy and takes only a moment. The Dive Alert PLUS uses a small amount of air from your SCUBA tank to make a piercingly loud sound in air or water. People have been able to hear a Dive Alert PLUS one mile away from diver in need above water. In conditions where visibility is limited, a Dive Alert PLUS can be a life saver. Underwater you can sound for attention quickly with a squeeze of the device.

The Dive Alert PLUS does not require any modification to your equipment, and it does not interfere with the normal operation of your equipment. The Dive Alert PLUS comes in three different models to accommodate different connectors: DV1, DV2, and DV3. Once the tank is turned on and the Dive Alert PLUS connected, squeeze the Dive Alert PLUS softly underwater for a subsurface signal. Or squeeze it firmly on the surface for a loud surface signal blast. Check that the Dive Alert PLUS is installed correctly and functioning properly before every dive. Also be careful not to point the Dive Alert PLUS toward yourself or toward anyone who is in close proximity to you when you activate the surface signal (it’s really loud!).

How it works

The Dive Alert PLUS 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 from the injection-molded thermoplastic body. The subsurface / underwater signal is produced by a percussion "buzzing" noise made by a piston hitting a stainless steel diaphragm much like a drum.
