With a durable, rugged body and ergonomic design, the Icom M73 VHF Transceiver features a slim, hourglass body and high intensity LCD that offers bright, easy to ready characters and a wide viewing angle. The Ic-M73 has been tested to survive after being submersed in 1.5m (4.9 ft) depth of water for 30 minutes - Ipx8 Submersible Plus. This radio uses a BTL (Bridge-Tied-Load) amplifier that doubles the audio output. Its internal speaker delivers a loud 700 m W audio output with clear sound. The IC-M73's 6 Watts of transmit power provide you with extended communication range while a large capacity Lithium-Ion battery allows 16 hours of operation under normal conditions.
