COSINE EFFECT ON TARGET VELOCITY
The Speedster III will measure the relative speed of a target as it approaches the Speedster III. If the
target is in a direct line (collision course) with the Speedster III, 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 Speedster III and the target’s direction of travel.
ADJUSTMENTS
The Speedster III will register speeds in both miles-per-hour (MPH) and kilometers-per-hour (KPH). Speed
units can be switched from MPH to KPH and vice-versa by pressing the trigger and then the power
button underneath the LCD display.
TRIPOD SOCKET
The Speedster III is designed with a tripod socket to mount and use the radar gun on a tripod. The
Bushnell SpeedScreen (sold separately, Bushnell product #101922) is an optional external display that
includes a tripod that can be used with your Speedster III radar gun.
