CHRONO START MICRO is the smallest autonomous GPS stopwatch in the world. The small dimensions of this stopwatch (69.5x50.5x21mm) allow it to be installed on any type of motor vehicle, even on pocket bikes or mini-motorcycles. Equipped with an internal battery (2 AAA batteries), a 50Hz GPS sensor, and a digital display, this GPS stopwatch is also extremely simple to operate. It can be used even on small tracks (for example, karting tracks) thanks to its function that allows you to set the width of the track. Simply set the finish line, then ride! The lap time is displayed on the screen at each lap, and START MICRO can record up to 82 laps divided into different sessions.
