Float 'n Flash

IC-M23 floats and lets you know where it is with the

flashing feature. The radio flashes in the water, even when the power is off!
It is smaller and lighter than any other buoyant marine handheld too.


Float’n flash*

With its innovative flashing red LED light, an overboard IC-M23 is easy to find, day or night. The light flashes even if the radio is turned off. * US patent pending.

Smallest and lightest in the world

As a buoyant VHF marine transceiver, the IC-M23 has the smallest and lightest body in the world.* * As of February, 2011, researched by Icom.

Energy-saving 3.7V circuitry*

The IC-M23 is powered by the 3.7V Lithium-Ion battery pack, BP-266, to reduce the capacity and weight of the radio. A newly developed PA circuit provides 5W (approx.) RF output and powerful 600mW (typ.) audio even at this low voltage, while saving battery consumption for 10 hours of operating time.* * Typical operation with Tx (Hi): Rx: standby=5:5:90. US patent pending.

Easy to see large LCD

The large, easy to see LCD (32×16 mm) offers a clear 2-digit channel number indication.

Built-in regular charger circuitry

Recharge the IC-M23 by plugging the wall charger directly in to the radio. By eliminating exposed metal charging points, the IC-M23 is even more protected from water damage.

Volume loud and mute functions

The volume loud/mute functions temporarily change the volume to the maximum/minimum level with two touches of a button. Depending on the background noise level, you can easily change the volume level to capture the received message.
