RT-B77 HELB
Personal Locator Beacon
The RT-B77 HELB is currently the most advanced and most powerful PLB available on the market for 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. Transmission of a dedicated ID and simple control of system and maintenance data by means of an IrDA interface are important benefits for operators of larger fleets. Autotest functions and status reports are announced by the system's speaker to guarantee high availability.
