Bushnell Velocity 101911 Owner's Manual

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.

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).

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.

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. 

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.

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 ”        “ will appear in the 

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.

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.
