Explanation of Position Tracking

Garmin VHF radios offer a feature called Position Tracking which allows a mariner to use interval position-request calls to locate and keep tabs on boats in the area. Regulations allow transmission of one position-request call every five minutes. You can call up to three vessels that your radio will alternate calling at five minute intervals. If a vessel does not respond to five consecutive position request calls, the vessel is removed from the position-tracking list.
