Standard Horizon HX100 Twin Pack
A pair of waterproof, floating VHF radios for around $150 is an excellent deal. The HX100 Twin Pack radios are low-powered, switching between 2.5W and 1W, but this is all you need for messing around in anchorages or harbors, which is what they’re intended for. Otherwise they have many of the same features as more expensive radios: programmable scan, NOAA weather channels, dual watch and so on.
