Easier to use than a radar gun, the RevFire measures pitch spin rate as well as speed. Professional coaches throughout the U.S. report dramatic results for pitchers' developing breaking ball pitches or 'movement' on a fastball when they have the benefit of RevFire's spin rate feedback.
RevFire spin measurement is a powerful new tool for scouts, but the RevFire is perfect for home use - no third person or radar gun pointing is required. The package includes a sports bag carrying case with monitor compartment, a RevFire monitor with lanyard, two 12-in RevFire softballs, 2 AA monitor batteries, and a users manual. Works only with RevFire baseballs or softballs. RevFire balls are for pitching training and are not for hitting.
