Pitchers and batters are quite familiar with the effect of spin on the trajectory of a ball. Scientists have studied the phenomenon and many have mathematically described the effect. More spin creates more
curve, movement, rise, or hop. It's all about deceiving the batter, but until now very few could measure it.
Training Advantages
• Pitchers respond well to instant objective feedback. With the RevFire they can more quickly learn
techniques that produce the best breaking ball, sinker, or rise ball. Rather than trying to overpower
the ball to impress a radar gun pointed at them, the pitchers focus on the proper release mechanics
required to achieve strong rotation. They gain an awareness of spin and a motivation to improve their
stats relative to their peers. Effective breaking ball pitchers can provide hard RevFire metrics to
college and professional recruiters.
• Coaches can evaluate pitching ability and technique with hard numbers, gain new insight into training
methods, identify pitchers whose spin fades as they tire, and see who's breaking ball is 'on' in the
bullpen. The fact that the RevFire does not have to be held in line with the pitch and pointed at the
pitcher changes the dynamics of pitching instruction. Subtle RevFire speed and spin measurement
can be done by the coach out of the line of sight of the pitcher. A softball coach can tell a pitcher that
her riseball, for example, can't be part of her game time repertoire until the spin rate is increased from
16 RPS to 23 RPS. The RevFire also adds a powerful new dimension to pitching prospect
evaluation.
Product Features
• Displays speed and spin rate after each toss of a RevFire ball.
• Logs maximum speed and spin each session.
• Counts the number of pitches.
• Measures spin rates with an accuracy of +/- 0.25 RPS.
• Speed reading is based on the ball's time of flight over the standard pitching distance selected by the user.
• Easier to use than a radar gun. No pointing or aiming is required. Coaches can use the monitor
anywhere within 40 feet of the catcher. There is no requirement to be in line with pitches.
• Pitchers do not tense up from looking into a radar gun.
• Pitching instructors can show breaking ball progress to others that otherwise can not see it, including
the pitchers and their parents.
• For use without a coach, the monitor has an Automatic mode of operation and built-in support for
placement on the ground next to the catcher or a lanyard to hang it around the neck.
• RevFire baseballs and softballs are official size and weight leather balls. They are not for hitting or
game play and are easily identified by their red and black stitching. Replacement balls available from the RevFire Corporation
