good features
I just put this radio in my boat after buying the oceanic and realizing that the WHAM I bought was only for the 525. The WHAM for the 525 has a better & more permanent charging tray, so I upgraded the radio rather than moving down in WHAM. My WHAM is positioned at the top of the companionway and is easily hard wired through the lights in the head and to the breakers.The 525 will also take NMEA info from a GPS, and transmit that info on the distress signal. Additionally, it will display a boat in distress on your GPS. The larger display will show coordinates so finding your position down below will be easy.
