M73 VHF Marine Handheld Radio | 156–165 MHz, 6 W, Submersible

Product Description

The M73 is an ergonomic, user-friendly, durable, and submersible VHF transceiver. The M73 has been tested for submersions in up to 1.5 meters of water for thirty minutes. This device is equipped with a wide viewing angle, high-intensity LCD screen that has bright, easy-to-read characters and a bridge-tied load amplifier that doubles the audio output of the internal speaker.
