The Scub-Alert is an underwater horn that allows you to signal your dive buddy effortlessly by the press of a button.  This horn generates a loud "quacking" 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.
