Whether you're running on a trail or skating down the boardwalk, you need a radio that's ready to play. The SRF-M85 features a slimmer digital tuner, so it's lighter than ever. The SRF-M85 comes with an armband and belt clip, so you can keep your hands free, and it has a built-in stop watch/split and pitch timer. Time your run, or sailboat race, whatever you want.
