The Velocity Handheld Radar Gun offers an excellent combination of accuracy, ease of use, and value. Measures the speed of a vehicle up to 200mph (322km/h), and is accurate to +/- 1mph (2km/h). When measuring the speed of a small object such as a baseball or tennis ball, it will measure speeds up to 110mph (177km/h). Its compact and lightweight design (only 13 oz.) makes the Velocity a breeze to hold and use for any race, qualifying, or practice session. Displays speed in miles or kilometers per hour on a large, easy-to-read LCD display. Outperforms other radar guns costing hundreds more. Includes draw-string storage pouch. Requires two C batteries (not included).
