Launch monitors can help you shoot lower scores with the golf swing and equipment you have right now (because they show how far you truly hit the ball with each club), but most are crazy expensive, big/bulky, require apps/downloads...and the cheap ones are often inaccurate. The new PRGR Black Pocket Launch Monitor is inexpensive, super accurate (it uses Doppler Radar ), and incredibly easy to use. It\'s battery powered - 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).
