To use the RevFire:
1. Run the RevFire app on an
iPhone or Android with Bluetooth
enabled.
2. Throw the RevFire ball. You must
throw a pitch with a full windup
and release.
3. If the RevFire ball’s motion
sensors detect an acceleration
event characteristic of a full
windup, followed by ball flight for
0.3 to 1.2 seconds, followed by
ball catch, the RevFire ball will
initiate transmission of speed and
spin information via Bluetooth
Low Energy (BLE) to the iPhone
or Android device running the
RevFire app which will display the
information.

2 MODES OF OPERATION
The RevFire handheld monitor has two modes of operation, AUTO and
BUTTON. Units ship in Auto mode. Auto mode is for use by a
catcher. It displays the spin rate and speed for every pitch without
requiring button presses. Button mode is preferred by observing
coaches and requires the user to hold the ON button down during a
pitch. Once the mode is set, the mode will be maintained until the
batteries are changed or the user changes the mode as described in the
section entitled “TO CHANGE MODE OF OPERATION”.
The appearance of a circular dot as shown below indicates that the
monitor is ready to track pitches and display the Revolutions Per
Second (RPS) and Miles Per Hour (MPH). Each toss detected by the
monitor will result in a beep and the display of RPS and MPH data. A
good knuckleball cannot be detected by the RevFire system.
A coach holding the monitor should stand within 40 feet of the catcher.
The monitor may be set next to or worn by the catcher as well. When
the monitor is used by the catcher, Auto mode must be used.
The monitor will turn off automatically if no pitch is detected or button
pressed for 2 minutes.

AUTO MODE (For use by catcher)
To monitor pitches, press the ON button. After pressing the ON button
there is no need for any further button presses. In Auto mode, both
pitcher-to-catcher and catcher-to-pitcher tosses will be monitored.
Auto mode is required if the monitor is used by the catcher. In Auto
mode the pitch must be caught. If throwing against a tarp or net, use
Button mode.
BUTTON MODE (Preferred by coaches)
In Button mode the monitor will display pitch data only for those
pitches thrown while the ON button is pressed. The circular dot will
appear only while the ON button is pressed. ON must be released and
pressed again for the next pitch. Button mode is best for coaches and is
required if the pitcher is throwing against a tarp or net. With Button
mode, the pitcher’s pitch data is not overwritten by the catcher’s return
toss to the pitcher or by balls dropped by the catcher. Also, the
pitcher’s pitch count is accurate. The RevFire monitor will revert to
Auto mode when the batteries are changed.
TO DISPLAY MAX RPS AND MAX MPH
The monitor keeps track of the greatest spin rate and speed detected.
To display these statistics, press the STATS button until the words
“MAX RPS” and “MAX MPH’ are displayed as shown below. The
MAX RPS and MAX MPH did not necessarily occur on the same pitch.

TO RESET MAX RPS AND MPH TO ZERO

TO DISPLAY PITCH COUNT
The RevFire monitor will count the number of ball tosses it detects. To
display the toss count, press the STAT button once or twice until the
count is displayed as shown in the example below:

In Auto mode, if the monitor is positioned such that it detects tosses by
both the pitcher and the catcher, the actual pitch count would be half
the value displayed. In Button mode, the count increases only when a
pitch is detected while the ON button is pressed.
TO RESET PITCH COUNT TO ZERO
With the toss count displayed, press and hold the STATS button until
the count is cleared to zeroes.
TO CHANGE PITCHING DISTANCE
The distance from the pitching rubber to the pointed tip of home plate
must be set in the monitor to get a correct speed reading. To display
the current distance press the STAT button until the distance is shown
in “Ft”. To change the distance setting, press and hold the STAT
button until the distance number changes. Release at the proper setting.
The monitor can be set to 35, 40, 43, 46, 46b, 50, 54, or 60.5 feet. 35,
40, 43, and 46 are for fastpitch softball. 46b, 50, 54, and 60.5 are for
baseball. For best speed accuracy, the catcher should place his/her feet
3 feet behind the point of home plate. Or, if throwing against a tarp or
net, place it 2 feet behind the point of home plate.

USING MULTIPLE REVFIRE BALLS
The RevFire monitor will track only one ball at a time – the first one
thrown after the monitor is turned on. If multiple RevFire balls are
being used nearby, you can select the ball you wish to track. The
monitor will lock onto the first RevFire ball thrown after the user
presses STAT and then ON and will IGNORE ALL OTHER
REVFIRE BALLS. To change balls simply press STAT, then before
the ball of interest is thrown, press ON.
LOW BATTERY INDICATOR
The AA batteries should be replaced with new Alkaline batteries at
least once a season or when the low battery indicator is displayed.
After changing the batteries, the pitching distance will be 60.5 Ft and
the mode will be Auto.
SPIN AND SPEED ACCURACY
The spin rate is accurate within +/- 0.25 RPS regardless of how far or
fast the ball is thrown. The speed is based on the ball’s flight time and
is typically within +/- 2 MPH of a ‘peak’ detection radar gun if the
catcher places his/her feet 3’ feet behind home plate and if the correct
distance setting is used. The location or position of the monitor does
not affect spin or speed accuracy. If the pitch hits the ground before
crossing the plate, the speed is not accurate.
THINGS TO REMEMBER
If the RevFire does not appear to be working, review the following:
1. The RevFire monitor tracks only one ball at a time. To switch
to a new ball review “USING MULTIPLE REVFIRE BALLS”.
2. For correct speed calculation, the distance setting must be correct
and the catcher must place his/her feet 3’ behind the plate.
3. Pitches thrown at the ground may not measure accurately.
4. Good knuckleballs cannot be detected with the RevFire.
5. Verify that the mode of operation (Auto vs. Btn) is as expected.
6. The first two tosses of a RevFire ball after it has been idle for 2 or
more minutes will not be detected by the monitor.
7. The monitor should be positioned 40 feet or closer to the catcher.
8. There may be radio interference (older cordless phones, wireless
baby monitors, wireless video transmitters) in the area. Try using
the ball away from homes or offices, or try turning off these
devices.
9. A small rattling sound inside RevFire balls is normal.
