Dive Alert is a company that was founded to create a way for dives in distress to get the attention of their dive buddies when needed. Not only will it alert anyone within a one mile radius on the surface with its piercing sound, but it will alert your dive buddies underwater as well with a buzzing noise that will be sure to turn heads. The system was designed to attach easily onto your equipment without any modifications at all, and the signaling device uses a small amount of air from your tank to make the attention grabbing magic happen. Dive Alert and Dive Alert Plus are safety devices designed to save divers’ lives.
