Works for Right and Left Handers. Keeps a history of your most recent 500 swings and measurements. Can measure your club head speed on practice swings. Weighs only 4.4 ounces with batteries included (that’s lighter than average smartphone!).
Works with other sports including tennis, baseball (pitch speed and bat speed), soccer and hockey.
PRGR is accurate (it uses Doppler Radar!), just turn it on, place it on the ground, and hit. You’ll see your swing speed, ball speed, smash factor, and distance with each club (carry and total).
