User manual BUSHNELL VELOCITY

[. . . ] #: 98-0338/11-03 Congratulations on the purchase of your Bushnell® VelocityTM. 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. [. . . ] 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. TARGET SPEED ACQUISITION A target can be anything that is moving faster than 10 M. P. H. To acquire the speed of a target, with the Velocity powered on, aim the will appear Velocity at the target and depress the TRIGGER. 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. There are certain mathematical properties of Doppler Radar that affect the accuracy of your Bushnell Velocity. 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. 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.
