ICOM pioneered the floating handheld VHF marine radio and others followed. Setting a new trend yet again, the M24 has a flashing light feature that activates when the radio hits the water, even if the power is off. If you accidentally drop this floating radio overboard, it's easier to find, day or night. AquaQuake draining function keeps water away from the speaker grill. One-touch Channel 16 access.
