This is the sports radar device that displays readings on an integrated LED screen that is readable from up to 50' away. The screen displays speed readings in 6 1/2"-high bright red numerals, allowing athletes to monitor from the playing field how fast a ball is thrown, kicked, or shot. Unlike typical radar guns that need to be operated by another person, the radar scoreboard automatically measures ball flight speed between 15 mph and 150 mph. The radar scoreboard stores the highest speed for each session and ever detected, allowing athletes to set goals and monitor progress. The device measures in mph or Km/h, has an integrated handle, and shuts off automatically after five minutes of inactivity to conserve power. Requires four C batteries. 7 1/4" L x 7 1/4" W x 45 1/4" D. (4 lbs.)
