The RT-B77 HELB is currently the most advanced
and most powerful personal locator beacon (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.
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.
