GPS Speedometer
GPS speedometers built for calibration-free speed tracking.
- Reads vehicle speed through GPS signal with no transmission sender required
- Built for swaps, classic cars, trucks, street rods, boats, and custom builds
- Simplifies installation where mechanical or VSS speed signals are not available
- Precision stepper motors for smooth, accurate pointer movement
- Built to perform for years without compromise
