Float 'N Flash

Icom pioneered the floating VHF marine radio and others followed. Setting a new trend yet again, The IC-M24 has a flashing light feature that activates when the radio hits water, even if the power is off! If you drop this floating radio overboard, it's easier to find than ever, day or night.

Float 'n flash*

With its innovate flashing red LED light, an overboard IC-M24 is easy to find, day or night. The light flashes even if the radio is turned off.
* US patent pending.

AquaQuake draining function

The vibrating "buzz" sound clears water away from the speaker grill.

Smallest and lightest in the world

As a 5W VHF marine transceiver, the IC-M24 has the smallest and lightest body in the world.*
* As of December, 2010, researched by Icom.

Energy-saving 3.7V circuitry

The IC-M24 is powered by the 3.7V Lithium-Ion battery pack, BP-266, to reduce the volume and weight of the radio. A newly developed PA circuit produces 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.

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-M24 by plugging the wall charger directly in to the radio. By eliminating exposed metal charging points, the IC-M24 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.
