SIERRA Speedo GPS, Arctic, 3" 60 MPH
The SIERRA Speedo GPS combines speedometer and GPS heading functionality in a single 3-inch instrument gauge. This versatile marine speedometer accommodates both slow-speed applications such as pontoon boats and high-speed performance vessels equipped with pitot tubes. The gauge displays speed in both U.S. and metric scales with an accuracy of ±1 MPH once the vessel is in motion, and includes an integrated LCD heading display showing course over ground with ±1 degree accuracy.
The instrument features a scratch-resistant domed glass lens and enhanced illumination system including through-dial and perimeter lighting for reliable readability in darkness or low-light conditions. The housing is fully sealed to IP 65 ingress protection standards and operates across a temperature range of -40°C to +70°C, making it suitable for demanding marine environments.
Connection options include a dedicated SIERRA GPS antenna (sold separately) or integration with an existing NMEA 0183 GPS device via included connectors. Optional eyebrow or square bezels are available as aftermarket accessories. The gauge draws minimal current at 0.15–0.20 amperes on 12 VDC power.
