Aquatec Duo-Alert

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.

Horn works both UNDERWATER and on the SURFACE

Above water range approx 0.25 - 0.5 mile

Requires just a tiny bit of air to activate the underwater horn.

Horn is very loud above water. Keep away from ears at all times.
