Rhotheta RT-B77 Locator Beacon

The RT-B77 HELB from Rhotheta is currently of the most advanced and powerful personal locator beacons (PLB) available on the market for man overboard (MOB) emergencies.

The RT-B77 is designed for automatic activation upon contact with water or inflation of the wearer’s life jacket and can also be activated manually.

This PLB also features a second frequency that can be used for testing or training purposes.
