Specifications
Still Mode speed range: 5 to 199 Km/h (3 to 150 mph)
When in Still Mode, speeds lower than five km/h will not be recorded. For example, if a baseball player throws a ball, the sensor can record the ball's speed even it is lower than 40 km/h. However; in the Move Mode and the object's speed must be higher than 40 km/h in order for the sensor to record the speed.
Move Mode speed range: 40 to 199 Km/h (25 to 150 mph)

When in Move Mode, speeds lower than 40 km/h will not be recorded. This feature prevents the sensor recording the speed of the player rather than the object. For example, if a soccer player runs towards the ball to kick it, it is impossible to run faster than 40km/h. However, the ball's speed will be faster than 40km/h. If Still Mode is used, the sensor may record the player's movement speed, not that of the ball. Using Move Mode ensures that the sensor records the ball's speed only.
Distance from the sensor (goal or net) to the object or player: Approximately max. 12 meters (40 ft.) and min. 1 meter. Battery requirement: Five AA batteries (not included)
