The AutoMeter GPS speedometer is a marine-grade 3-3/8-inch instrument that delivers accurate speed without calibration when paired with AutoMeter's GPS antenna or many aftermarket receivers. The configurable Rally Nav display shows odometer, trip, time/date, GPS coordinates, heading, compass, and peak speed recall. A sealed front bezel and UV-protected dial paint increase resistance to water and sun exposure for boating use.
