compact, rugged VHF radio built for the harsh marine environment.
softkey menu operation,scan functions, dual/tri watch, 25/1 Watts, channel-change mic, Class D DSC, and IP67 waterproofing.Internal GPS with external puck antenna.
Not only is the unit waterproof, it is submersible for up to 30 minutes at a depth of 1 meter.
The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call.
You will hear better, be heard better. The new menu system provides easy and intuitive operation.
The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons.
The directional keypad allows you to perform various operations and settings.
