Thank You for purchasing the golf industry’s state-of-the-art DigiFlex™ Frequency Meter
2.0. You should find it simple to operate. Please follow the instructions in this manual. If
you have any questions, please call 1-800-437-1314.
The DigiFlex™ Frequency Meter 2.0 is the necessary hardware to check the shaft
frequency of assembled clubs and raw shafts for the purpose of comparing.
Our versatile clamping system ensures the correct clamping pressure for accurate and
repeatable CPM readings. It clamps clubs with grips, or raw shafts by changing to the
shaft clamps. The tapered and contoured Grip Clamp will clamp all shafts including
“Big Butt” diameter shafts. The clamping pressure can be adjusted to prevent breaking
fragile graphite shafts. The clamps interchange in seconds with an Allen flange screw.
The DigiFlex™ Frequency Meter 2.0 oers accuracy, consistent clamping, and versatility
that makes it the best in the industry.
All products manufactured by Mitchell Golf come with a one year warranty, and are
guaranteed against defects and workmanship.

Warning
The DigiFlex™ Frequency Meter 2.0 uses a Class 2 laser module. Caution should be
exercised when using the DigiFlex™ Frequency Meter 2.0 to avoid looking directly into the
laser or reflections of the laser beam. Permanent eye damage can result from exposure
to laser. Always use laser approved safety glasses (rated for 650nm wavelength) or the
plastic shaft collar included or piece of black tape to prevent reflections when measuring
a chrome or other reflective shafts.
The DigiFlex™ Frequency Meter 2.0 uses a lithium-ion battery as its power source. Care
should be taken not to store the DigiFlex™ Frequency Meter 2.0 in extreme temperatures.
The safe storage temperature range for the DigiFlex™ Frequency Meter 2.0 is between
45° F - 100°F. Operating temperatures should not exceed 95°F.
Lithium-Ion Battery Management System
The DigiFlex™ Frequency Meter 2.0 incorporates a lithium-ion battery management
system that continuously monitors the charge rate and discharge level of the battery.
This is necessary to maximize the life of the battery and optimize performance. The status
of the battery and charging are displayed on the upper right side of the LCD display.
Do not attempt to replace the DigiFlex™ Frequency Meter 2.0 battery yourself—you
may damage the battery, which couldcause overheating, fire, and injury. The lithium-
ionbattery in your DigiFlex™ Frequency Meter 2.0 should be serviced by Mitchell Golf
LLC, and must be recycled ordisposed of separately fromhousehold waste. Dispose of
batteries according toyour local environmental laws and guidelines.

•Frequency is the best measure of flex.
•Deflection method is a measure of a shaft’s beam strength.
•Rigid objects have a natural frequency.
•Rate of frequency is not dependent on the amount of force required to create
oscillation.
•Frequency is the number of times a shaft oscillates in a unit of time.
•CPM (cycles per minute) is the measurement of the number of times a shaft
oscillates in one minute.
•Frequency Gradient/Slope is the progression of cycles per minute between
each club in a set.
•Flat Line/Single Frequency is the same cycles per minute for each club in a set.
•Flex is the designation of a shaft’s resistance to bending.
•Shaft Beam Length is the distance from the edge of the clamp to the center of
mass of the club head or shaft weight.
•Face Plane Oscillation is measuring cycles per minute of a shaft in the same
plane that the clubs face is aimed.
•Dampening is the eect on CPM readings caused by grips or a variation in
clamping pressure.
•Oval Oscillation is when the shaft oscillates in a pattern that is not straight.
•When comparing shafts of equal length, the higher the CPM reading, the stier
the flex.
•Each swing weight increase in a club will equal one (1) CPM decrease in
frequency.
•Each swing weight decrease in a club will equal one (1) CPM increase in
frequency.
•Each 2 gram club head weight change is equal to one (1) CPM change in
frequency.

The RST (Reset) button clears the last results and sets
the DigiFlex in ready state (DigiFlex display will show
“Ready”). The DigiFlex will not respond to any other
button presses until it is in ready state. After every
measurement, steady the club shaft so there is no
movement. Press the RST button to prepare for next
measurement. See image 3-1.
The DigiFlex will provide an average of over 5 samples
based on the initial sample. Change the sample
mode by pressing the BLUE button. In sample mode,
the DigiFlex will display a total of 5 samples based on
the initial sample. The first measurement will be “Initial
Measurement”. All subsequent measurements will be
displayed as “AVG#:xxx(xx) CPM. Once the 5th average
has been measured and displayed, the DigiFlex will
start the averaging process over again from “Initial
Measurement”. Averaged results can be displayed in
integer or decimal mode. See image 3-2.
NOTE: The AVG mode setting is not retained in memory.
Change the sample mode by pressing the BLACK
button. While in Integer mode, the DigiFlex will round up
or down to the nearest whole number. For example, if
the resulting measurement is 285.35 CPM, the displayed
result will be 285. If the measurement was 285.53 CPM,
the result will be displayed as 286. While in Decimal
mode, all measured results will be two decimal places.
The display mode setting will be retained in memory
and set after the next power up. See image 3-3.
