PT9 PLS

Never ending power for your beacon.

The Acoustic Beacon with Powerloss Switch.

The PT9 C-PROOF PLS is battery operated and primarily consists of an electronic module and a switch. Protected by a cylindrical, water-and weather-resistant housing, the PT9 C-PROOF PLS withstands extreme environmental conditions, high impact and deep-water pressure of up to 6000m. Immersion in fresh or salt water activates the PT9 C-PROOF PLS. The battery capacity is dimensioned in such a way that the PT9 C-PROOF is able to send this ultrasonic signal with constant signal intensity for the duration of at least 30 days.
