The IC-M73 from Icom offers fixed-mount quality in a handheld VHF marine transceiver. A bolstered amplifier doubles the audio output, and a bass boost function provides richer sound for clarity in both transmit and receive. Active noise-canceling technology eliminates up to 90 percent of background noise. Last Call Voice Recording saves the latest incoming transmission for up to a minute so you can replay missed messages. A wide-angle-view, high-intensity LCD screen allows for easy reading in bright daylight. The waterproof body and speaker are completely submersible, and Icom's AquaQuake function clears the speaker of water for clear reception. The high-capacity lithium battery offers up to 16 hours of operation on a charge with 6 watts of transmitting power.
