Battery Installation
Power ON/OFF
The ProTimer operates using a 9 volt battery for power. It is
important to use Alkaline or Lithium batteries (not carbon) due
to the power demand of the buzzer and display backlighting.
Install the battery in the compartment on the rear of the unit.
Once installed, the ProTimer will briefly display a sign-on
message, followed by the home screen.
Note: If at any time you suspect the unit is not functioning
properly, try resetting it (see page # 14).
To turn the unit ON, press the SET DECR/ON button.
After 10 minutes of inactivity, the ProTimer will turn off
automatically.
You may also turn it OFF by pressing the MENU REV/OFF
button for approximately 3 seconds.

Basic Operation
If you haven’t done so already, advance through the 14 menu screens and make any
adjustments to the default settings to suit your needs.
• The active settable value will be flashing.
• Some of the screens have more than one settable value, which will require
multiple presses of the menu button to advance.
• When changing a setting with the SET buttons, if you hold the button, it will
advance the digits automatically.
• Settings are automatically saved.
Pressing the START button from all screens (except Clear Data) will return to the
home screen and begin a new string.
5
Headset Jack
A standard 3.5mm stereo headset jack is located on the side of the unit. The Piezo
beeper is disabled when a headset is connected for a private practice session. The
beeper volume control will also change the headset volume level.
Shot Detection
Each time a shot is detected, it will be added to the shot string. The timer will
automatically calculate the split time, which is the time between the current shot
and the previous shot. The ProTimer can store up to 70 shots per string. Subsequent
shots will be stored by overwriting the previous value of shot number 70. If a shot is
detected after 199.9 seconds, the display will “wrap-around” and start over, so the
actual time would be 199.9 + the displayed value.

PRO TIMER

Individual Menu Screen Detail
Review Shot String
From the home screen, pressing MENU/FWD, SET/INCR, or SET/DECR will advance
to the review screen. Shots will be displayed on the shot review screen in a “one
shot per line” format. Reading from left to right, the shot time appears first,
followed by the shot number, and finally the split time.
When navigating to the review shot screen after the completion of an event, the
first shot will appear on the 3rd line, and the last shot will appear on the 2nd line - if
there are 4 or more shots in the string. This is intended for the user to quickly
locate the first and last shot information without keystrokes.
Use the SET-INCR/DECR buttons to scroll through the shot string to review if there
are more than 4 shots in the list.

PRO TIMER
Par time
The par time settings create multiple beeps based on time intervals from the start
beep. The ProTimer has the capacity for up to 5 par times which will automatically
occur at the user settable time interval for each. The default settings are zero for
all 5 par time settings, which effectively turns them off, so in this case there will
be only the start beep at the beginning of an event.
Setting the first par time to a value other than zero will give you a beep at the
start, and another at the end of the par time period. Setting of par times 2 through
5 will string the beeps together in order. When a value of zero is set in any of the
par time locations, it will halt any subsequent values from being active.
Par time is adjustable from 0 to 199.9 seconds.
Start Delay Type
The start delay can be configured for instant, fixed, or a random value based on a
minimum/maximum time frame from the start beep.
INSTANT- The default setting of INSTANT will start a new shot string immediately
upon pressing the start button.
RANDOM- Changing the setting to RANDOM will enable the minimum and
maximum values to appear on the screen. The settable range is from .10 seconds
to 9.90 seconds.
FIXED- If the RANDOM values are both set for the same amount of time, the delay
will be FIXED at that value.

PRO TIMER
Backlight ON Time
The display backlighting can be set for a specific amount of time to remain ON after
pressing a button.
The settable range is 0 to 99 seconds. Longer time intervals will reduce battery life.
Start Signal LED
The LED indicator on the front of the unit can be enabled/disabled by pressing one
of the SET buttons.
This feature is intended for use when hearing the beeper is difficult, but could also
be considered as an alternative method for beginning a stage.
Beeper/Headset Volume
The volume control for beeper and headset volume can be adjusted from OFF to
maximum with 10 levels.
Home Screen Type
There are 3 home screen configurations to choose from.
• Review Direct
• Single Time Only
• Rounds Per Minute
9

PRO TIMER
SINGLE TIME ONLY
This selection will show only the time to the last shot
in a large format.
ROUNDS PER MINUTE
This mode is used for measuring the rate of fire
rather than time intervals. The screen layout is
similar to REVIEW DIRECT. After the start beep, fire
shots; the timer will display the rounds per minute
based on the number of shots and the time between
the first and the last shot. Shots recorded more than
199 .99 seconds after the start beep will render
readings invalid until the unit is restarted. The
ProTimer can detect shots at rates up to 1800 RPM.
10
REVIEW DIRECT (DEFAULT HOME SCREEN)
This selection is the default setting which
shows more information with the penalty of a
smaller “time to the last shot”. The time to
the first shot, current split time, and
date/time are all included on this screen.

PRO TIMER
Shot Dead Time
The SHOT DEAD TIME feature is used to reduce false shot recordings due to echoes or
ringing normally associated with indoor use. Once a shot is detected, the ProTimer will
disregard subsequent shots (echoes) for a short period of time. The default setting is
.11 seconds, but can be adjusted from .05 to .12 seconds. If your split time between
shots is less than .11 seconds, an adjustment will be necessary.
Shot Sensitivity
The sensitivity adjustment range is from 0 (lowest) to 25 (highest). The default setting
of 13 will work with most types of firearms. With the high range settings, keep in mind
that there may be false shot detection from handling or other noise sources.
Date and Time
Settings for the date and time are entered on two screens and are displayed on the
REVIEW DIRECT, and ROUNDS PER MINUTE home screens. It is also recorded for
reference when a shot list is stored in the shot string memory.

Hit Factor Scoring
In order to obtain the Hit Factor (points per second) score, first you must complete
a stage to record the time to the last shot, then enter values for TOTAL STAGE
POINTS and POINTS DOWN on the Hit Factor Scoring screen.
The score will automatically be calculated on the top line of the display. You can
adjust the time to the last shot value in order to see how the score is affected by a
different amount of time.

PRO TIMER
Clear Data
Use the Clear Data screen to delete unwanted strings by pressing the START
button. This cannot be reversed!
Battery status, info and warning screens:
The battery icon shown on the display will appear as
-FULL from 8.4 to 9.5 volts
-1/2 from 7.8 to 8.3 volts
-EMPTY from 7.3 to 7.7 volts
-FLASH/EMPTY from 6.5 to 7.2 volts
A “backlight disable” message will appear when the unit is powered ON and the
battery is low. This will conserve power in case a new battery is not readily
available.
A “low battery critical warning” message will appear when the unit is powered ON
and the battery is too low for operation. The unit will shut down and a new battery
will be necessary for continued use.
Review Previous String
Previous strings of fire can be recalled for review by selecting one of the flashing
numbered values on the Review Previous String screen. The corresponding date
and time stamp will be updated as the number is changed.
The unit will store up to 50 strings, with up to 70 shots per string along with the Hit
Factor scoring data. if the max number of strings is exceeded - the first (oldest)
string will be purged.

PRO TIMER
Battery Life and power consumption
When the ProTimer is powered OFF, a very small amount of power (approximately
40 microamps) is consumed in order to retain the date/time clock settings. If the
unit will be put in storage for several months or more, it is recommended to remove
the battery to avoid unnecessary loss of battery life. The only penalty is that the
date and time will have to be reset. The calculated lifespan of a (new) 600mA
alkaline battery in sleep mode is 800 days. A lithium battery has a typical rating of
750mA. Under normal use, a lithium battery will provide approximately 30 hours of
service and an alkaline battery will provide approximately 25 hours of service.
14
Memory info
The ProTimer will retain up to 50 shot strings, with up to 70 shots per string, and all
settable values in non-volatile memory. (except date and time)
This means that they will not be lost during battery changes.
Resetting to Factory Defaults
To restore the factory default settings, hold down the start button, connect the
battery, and look for “initializing” message on the display. Release the start button
and follow the on-screen prompt to complete the process.
