This device is used to measure the speed of a moving surface. For karts, simply hold it lightly against the outside of the spinning rear wheel of a jacked-up kart. It uses a Cateye bicycle speedometer to measure and display the speed. Automatically goes to sleep - automatically wakes up to take a reading. There is a 10:1 pulse rate reduction circuit in the head - meaning that it has 2 lithium coin batteries - one in the head and one in the display.
