The Scub-Alert is an above & below water horn that allows you to signal your dive buddy effortlessly by the press of a button. This horn generates a loud "buzz" sound by using tiny pulses of air to rapidly vibrating a steel disk.

Use this underwater horn to get your dive buddy's attention both in emergency situations or just to show him something interesting.
