Garmin offers communications safety
for mariners worldwide. All include
Digital Selective Calling (DSC),
a global protocol that uses channel 70
to transmit and receive digital messages.
Garmin VHF radios equipped with DSC
can send and receive digital emergency
messages, private calls and general calls
and let you call attention to VHF calls
by using stored Maritime Mobile Service
Identity (MMSI) numbers. DSC significantly
improves the chances of rapid rescue.
