Q:  How long do the balls last?
A:  The balls should last for more than 25,000 pitches or for more than 4 years on the shelf.

Q:  Does the location of the monitor affect the accuracy of the measurements?
A:  No.  Neither the location nor the orientation of the monitor will affect the accuracy of measurements.  The
monitor may be set down next to the catcher or carried by the coach.  The monitor does not have to be
pointed toward the pitch or the pitcher.  However, if the monitor is too far from the catcher, the pitch will not
be detected by the monitor.  

Q:  Does the pitch type, pitch speed, spin axis, or distance thrown affect the spin rate accuracy?
A:  No, spin rate accuracy is not affected by these factors.  Whether tossing the ball one foot into the air at
your desk or throwing it 100 feet, the measured spin rate is within 0.25 RPS of actual.

Q:  What factors affect the speed measurement accuracy?

For a 60 MPH baseball pitch, if a catcher places his feet one foot closer to home plate than the
recommended 3 feet, the RevFire will tend to read about one MPH higher than the speed shown by a
peak-detect radar gun.  Similarly, if a catcher places his feet one foot further from home plate, the RevFire
will tend to read about one MPH slower.

If the steps below are followed, the RevFire is normally within 2 MPH of a peak-detect radar gun reading.
1.  Check that the pitcher to home-plate-point distance is correct.
Sometimes this distance, especially in bullpens, is off by 1 or 2 feet.
2.  Set the RevFire distance setting to the correct pitching rubber to home plate setting.
3.  Have the catcher place his/her feet 3' from the home plate point.

Q:  Why can't I hit the RevFire ball?
A:  Although the balls are very durable, the RevFire ball contains electronics that could be damaged by the
impact of a bat against the ball.  Throwing against hard surfaces should be avoided as well since it will
break down the ball core, leather, and seams faster.  We recommend that catchers in front of a hard wall
place protective netting or padding between the themselves and the wall.  Occasional tosses into the dirt or
a backstop are not a problem.

Q:  Can I get the ball wet?
A:  Yes, RevFire balls can get wet and will work when wet.  They should be kept dry if possible for maximum
life of the leather.
