The Sierra 781-627-120P 120 mph Speedo GPS in Black Premier Pro style gives you accurate speed and heading at a glance. Its 3" dial reads 0–120 MPH with ±1 MPH precision, while the built-in LCD shows your course over ground. Durable curved glass resists scratches, and automotive-style lighting keeps the display readable day or night. Works with our GPS antenna or any NMEA 0183 GPS device—perfect whether you're cruising a pontoon or pushing a performance boat.
