The Classic GPS Speedometer delivers clean, accurate speed data without speed sensors, gear ratios, or tire-size calibration. Just connect power, mount the waterproof GPS antenna, and drive. It locks onto free worldwide GPS signals with no subscription required, making it a smart fit for manual, automatic, custom, swapped, and off-road builds where traditional speed sensors fall short. A precision stepper motor keeps pointer movement smooth and stable, while the internal microprocessor, slim case, spin-lock mounting ring, solid aluminum bezel, and weather-resistant construction make it ready for street, track, and trail. Made in the USA and backed for life.
