Speedhut 4" 80 mph GPS Speedometer / 8K Tachometer Gauge (R4-DS9-REV)
Experience enhanced driving with the Speedhut 4" 80 mph GPS Speedometer / 8K Tachometer Gauge (R4-DS9-REV). This innovative dual gauge integrates precise GPS technology for real-time speed measurement, removing the complexities of traditional speed sensors and the need for calibration due to tire size or gear ratios. Installation is straightforward, requiring only a 12V power connection and the included waterproof GPS antenna. The speedometer operates globally using free GPS data reception. Complementing the speedometer is a highly accurate tachometer, compatible with virtually any engine and tach signal exceeding one volt. Its advanced design ensures pointer accuracy even under demanding racing conditions, functioning across a wide range of engine pulse outputs (1/2 to 6 pulses per revolution). This robust gauge offers a comprehensive solution for monitoring crucial vehicle data with ease and reliability.
