The Garmin GPS company manufactures a number of GPS units designed especially for use with boats. The Garmin 182 automatically interacts with a boat's positioning and radio system, the VHF-DSC, or DSC for short, to determine the boat's position and review distress calls. Once you connect the Garmin 180 to the VHF-DSC system, you can easily obtain any relevant information provided by the DSC system directly on your Garmin GPS unit.
