● Position the device 3.5 feet behind the net, and pitch towards the net.
* Ensure that anyone in the surrounding area is safe before pitching, and pay sufficient
care to rebounds off the net.
* The standard installation layout shown below assumes that you are pitching a baseball.
When using a softball or other type of ball, there may be cases in which measurements
cannot be made, even when setting the device in the position shown below.
● When making measurements during pitching practice, position the device behind the catcher
(in the position where the umpire would stand).
*In some cases, measurements cannot be made where the course of the incoming ball takes
it into the shadow of the catcher.

The speed that can be measured using the device in the installation position shown above is the
speed of the ball directly before it is caught by the catcher. This is the ball speed actually experienced
by the batter, and can be said to be an important factor in determining the quality of a pitch. Although
the actual percentage may differ depending on ball type and the amount of spin applied to the ball,
final ball speed is typically around 5–10% slower than the pitching speed (i.e. the initial speed of the
ball as it leaves the pitcher’s hand).

Radar gun mode has two measurement modes: Bat Mode and Ball Mode.
【 Bat Mode 】
Use Bat Mode to measure baseball bat swing speeds, or speeds of other objects where the
change in speed is great. Aside from baseball, it can also be used to measure swing speed in
other sports such as tennis and hockey.
* In some cases, measurement may not be possible due to the structure or material of
the bat (or other piece of equipment).
* Affixing aluminum foil or other metallic foil to the relevant part of the bat (or other piece
of equipment) may make it easier to obtain a measurement.
【 Ball Mode 】
Use Ball Mode to measure baseball pitching speeds, or speeds of other objects where the subject
moves at a largely constant speed. Aside from baseballs, it can also be used to measure the
speed of balls in other sports.
* In some cases, measurement may not be possible due to the structure or material of
the ball.
<About the counter function>
In radar gun mode, the device is equipped with a counter function that displays the number of
measurements made at the bottom of the screen. You can use this function to count practice
swings or pitches made.
* Counting is possible up to a maximum of 999 counts. However, the device history can
only store up to a maximum of 500 past measurement data entries (for all modes
combined).
* Erasing the history also erases the count.
PRGR Portable Launch Monitor -Red Eyes Pocket- stores a maximum of 500 past measurement
data entries (for all modes combined). The history can be displayed by carrying out the following
procedure.
•Press the upwards-facing scroll button

→The previous measurement result will be displayed on the main screen, and the history
display at the top of the screen will roll back by one entry.
*Press and hold down the scroll button to scroll continuously.
*Once the total number of data entries exceeds 500, past data entries will be overwritten
automatically in sequence, beginning with the oldest entry.
<Erasing the history>
Press and hold down both scroll buttons simultaneously for more than 2 seconds.
Histories and counts for each mode will be erased.
Possible areas of measurement and positioning directions
● As a general rule, the device is capable of measuring the speed of balls passing through
the areas shown below. The areas shown are guidelines for when using a baseball. In some
cases, measurement may not be possible due to the material of the ball.
● Where there is an angle between the direction of movement of the target and the direction
in which the device is facing on installation, the speed measured will be slower than the
actual speed.
Example: when measuring a target moving at 70 mph
0 degrees: 70 mph (100%)
10 degrees: 69 mph (98%)
20 degrees: 66 mph (94%)
30 degrees: 61 mph (87%)

●The device will not turn on
◆Check that the batteries have been inserted in the correct direction.
◆Remove and reinsert the batteries, and check that the metal parts (i.e. terminals) are in
contact.
◆Check the batteries’ level of remaining charge and, where necessary, replace them with new
batteries.
●The device will not take measurements
◆Check the “Install/position the device” section of this manual to confirm that the device has
been installed/positioned correctly.
◆In some cases, when hitting the ball high in the air using a wedge or other such club, the ball
speed will be slow and the smash factor will be below the prescribed level, preventing
measurements from being taken. (This is a result of the specifications of the device itself, and
is not a malfunction).
●The measurement values are strange or abnormal
◆Measurements of club head speed are made in accordance with PRGR’s own criteria.
Differences may arise between measurements taken with this device and those taken with
devices manufactured by other firms.
◆Check the “Install/position the device” section of this manual to confirm that the device has
been installed/positioned correctly.
◆Depending on the type of ball used, in some cases, ball speed may not be displayed correctly.
Measurements cannot be made using plastic balls, sponge balls, or other balls designed for
practice-only use.
◆When practicing swinging without a ball, only club head speed can be displayed. In some rare
cases, ball speed and distance of flight may be displayed when practicing swinging without a
ball. These values are due to noise interface, and are not correct measurement results.
