How Your CobraMarine VHF Radio Works
This radio is a VHF transceiver for fixed mounting on your boat. It gives you 2-way
vessel-to-vessel and vessel-to-shore station communications, primarily for safety
and secondarily for navigation and operational purposes. With it, you can call for
help, get information from other boaters, talk to lock or bridge tenders and make
radiotelephone calls to anywhere in the world through a marine operator.
Besides 2-way communications, in the U.S.A., the radio can provide quick
access to receive eight NOAA (National Oceanographic and Atmospheric
Administration) and two Canadian weather channels for alerting you to weather
emergencies with a tone on a weather channel you can select for your area.
