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. 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. The large, easy to see 1.5″ LCD offers a clear 2-digit channel number indication. 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. 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. The Icom M24 is IPX7 waterproof, has a 4-step battery indicator, NOAA weather and weather alert, full scanning and dual watch functions, and AquaQuake speaker draining feature. Includes radio, battery pack, charger, belt clip, and hand strap. Three year warranty.
