Enjoy complete control of your IC-M504, and IC-M604 fixed-mount marine VHF radio from a remote location with the Icom HM-162B CommandMic III microphone. The CommandMic III--which fits comfortably in the palm of your hand--in effect serves as a second station for your vessel. Need to call a fellow boater or make a distress call but don"t have time to trudge all the way to the main radio? Pick up a CommandMic III, an ideal communications accessory for the deck, fly bridge, or main cabin (the mic must be located within 70 feet of the main radio). The mic sports such features as a sizable built-in LCD, an extra-large 1.7-inch speaker, and a multifunction jog dial that offers quick and easy access to all the controls on your radio, including channel selection, volume, squelch, menu settings, DSC calls, and foghorn functions. You can even use the CommandMic III to talk with the main unit as an intercom, making onboard communication easier than ever.
