DiveAlert is an innovative dive safety solution, designed to help the diver signal emergency. The device is essentially an air horn, that uses a small amount of gas from the diver’s tank to produce an exceptionally loud noise. The lightweight design and quick-connect / disconnect hose couplings make it easy to use and convenient to carry as a part of the diver’s buoyancy compensator. This piece of gear can be heard over comparatively large distances and is, therefore, particularly useful under the conditions of limited visibility. All of the aforementioned factors make the Dive Alert a worthy buy and possibly even a real lifesaver.
