Not only is the ICOM M1V waterproof to JIS 7 standards, but it is also designed with a non-corrosive construction to keep the harsh marine environment out. The M1V is the only VHF radio in its class to use a powerful Lithium Ion battery pack, so no more worrying about if it is fully discharged or not. With typical operation you will get an incredible 12 to 14 hours of operating time - nearly 2 times longer than most Ni-Cds. Also this unit is equipped with a battery indicator. A large, backlit LCD offers easy to read channel numbers and descriptions.

Yes descriptions!

Now you can program descriptions for each channel up to 10 alphanumeric characters per channel. The M1V has all the scanning features you will ever need with; dual and tri-watch, select scanning and scan-which will scan through all the channels. Just like all other handheld's you have choice from 1 or 5 watts of transmitting power with a touch of a button. You also have a 16/9 button for emergencies. As you can see, the M1V is fully equipped for that serious boater. Includes Lithium Ion battery and charger.
