Introducing the world's first*1 5W VHF marine transceiver that floats! If you drop the IC-M34 into water, the radio comes up to the surface so that you can easily retrieve it from out of the water. As the radio has a rugged submersible body*2, it will keep on working even after it has been submerged. Reliable marine communications that won't let you down in or out of your boat! When floating in calm water, the base of the radio is level with the water surface.
