Congratulations on the purchase of your Bushnell® Velocity™. The Velocity
is a precision speed radar instrument designed to provide many years of
enjoyment. These instructions will help you achieve optimum performance
by explaining the adjustments and features as well as how to care for this
precise speed measuring instrument. To ensure optimal performance and
longevity, please read these instructions before using your Bushnell Velocity.

INTRODUCTION

Your Bushnell Velocity uses digital technology to provide instantaneous
speed measurements to +/- One-Mile per Hour (MPH) accuracy (+/- 2 KPH).
The Bushnell Velocity is a simple, point and shoot radar gun for all kinds of
sports enthusiasts. The Bushnell Velocity measures the speed of a baseball
at 10-110 MPH from 90 feet away from the ball (16-177 KPH @ 27m), and
the speed of a race car from 10-200 MPH at 1,500 feet away (16-322 KPH @
457m).

BATTERY INSTALLATION

Your Bushnell Velocity operates on two "C" size alkaline batteries. To install,
remove the battery cover by rotating the battery cap counterclockwise.
Insert both batteries positive end first and replace cap by depressing and
rotating clockwise.

HOW TO USE

1. Turn the Velocity "ON" by pressing the button underneath the LCD
display.
2. Aim the Velocity at the target and depress the TRIGGER. As a quick
reference to accuracy, remember to keep your target's direction of
travel in a direct line with you and not perpendicular to you.
3. Turn the Velocity "OFF" by pressing the button underneath the LCD
Display for 3 seconds or until display shuts off.
NOTE: The Velocity contains an automatic battery saving shut-off feature. After
10 minutes of non-use, the Bushnell Velocity will automatically shut off.
If a battery symbol appears on the lower right hand corner of the display, the
battery voltage is beginning to deteriorate, meaning new batteries should be
inserted. Remove batteries if storing long-term.

SWITCHING FROM MPH TO KPH / KPH TO MPH

To change the display readout from MPH (miles per hour) to KPH (kilometers
per hour), the Velocity should be powered on first. While holding down the
TRIGGER, press the power button underneath the LCD display. To switch back
to MPH, repeat this procedure.

TARGET SPEED ACQUISITION

A target can be anything that is moving faster than 10 MPH (16 KPH). To
acquire the speed of a target, with the Velocity powered on, aim the Velocity
at the target and depress the TRIGGER. A radar icon "
upper right corner of the LCD display. This indicates the Doppler Radar is
functioning. The radar will continue to be active searching for speed until
the trigger is released. Upon release of the trigger, the fastest speed captured
within that series will automatically be displayed. The speed of the target will
appear on the LCD display in MPH. There are certain mathematical properties
of Doppler Radar that affect the accuracy of your Bushnell Velocity. Please
read "COSINE AFFECT ON TARGET VELOCITY" below. As a quick reference to
accuracy, remember to keep your targets direction of travel in a direct line
with you, and not perpendicular.

COSINE EFFECT ON TARGET VELOCITY

The Velocity will measure the relative speed of a target as it approaches the
Velocity. If the target is in a direct line (collision course) with the Velocity
the measured speed will be exact. As the angle of incidence increases, if
you move either right or left of this direct line, the accuracy will decrease.
The measured speed will decrease as you move off this centerline. This
phenomenon is called the Cosine Effect. It is called this because the
measured speed is directly related to the cosine of the angle between the
Velocity and the target's direction of travel.

How do you measure exit velocity with the gun? What’s the best way to position the gun for accuracy?

To measure exit velocity with the Bushnell Velocity 101911:

1. Aim directly at the target's path: Point the radar gun in a straight line with the direction the ball or object is moving (a collision course).
2. Distance: For baseballs, stand up to 90 feet away; for vehicles, up to 1,500 feet.
3. Hold steady and press the trigger: Keep the radar gun steady and press the trigger to get a speed reading.

Best position for accuracy:
- Align the radar gun directly with the object’s path.
- Avoid angles to the side, as this causes the Cosine Effect, reducing accuracy.
- The closer the alignment to a straight line, the more accurate the speed reading.

My radar gun won't turn on with new batteries

1 comments:

The Bushnell Velocity 101911 radar gun may not turn on with new batteries due to the following reasons:

1. Incorrect Battery Installation – Ensure both C alkaline batteries are inserted with the positive end first, as specified in the manual.
2. Battery Cap Not Secure – The battery cap must be properly depressed and rotated clockwise to ensure a secure connection.
3. Battery Voltage Issue – Even if the batteries are new, they may not have sufficient voltage. Try using another set of fresh batteries.
4. Automatic Shut-Off Feature – If the gun was left unused for 10 minutes, it may have shut off automatically. Turn it back on manually.
5. Internal Malfunction – If all steps are followed correctly and the device still does not turn on, there could be an internal issue requiring service.
