Check that speed just like the pros!
Measuring velocity in experiments is difficult and often requires complicated, fancy equipment... but not with the Velocity Radar Gun. Accurate velocity readings are now as easy as "point and shoot". Aim the gun at a moving object and pull the trigger. When released, a velocity reading will be displayed on the large LCD display. Safely measure the speed of a tennis ball 90 feet away. Experiment with the velocity of vehicles from up to 1500 feet away. Uses digital technology and DSP (digital signal processing) to obtain +/-1 mph accuracy, 10-110mph range for small objects and, 10-200mph range for vehicles. Powered by two C batteries (not included).
