object. This is the case in sports where players are running and hitting. For example, if a soccer player runs towards
the ball to kick it, since it is impossible to run faster than 25 MPH. However, the soccer ball's speed will often be
faster than 25 MPH and will be recorded.

ADDITIONAL SUGGESTIONS FOR USE
1. Always place the Radar Coach™ behind a goal or net to protect the unit from being struck by a ball.
2. Make sure that the distance between the Radar Coach™ and the item being measured is no more than 40 feet (12
meters) away from the unit, and no less than 3 feet (1 meter) for the most accurate readings.
3. You may find that the tripod (included) provides a more accurate reading, but the unit can also be placed directly on the
ground.
4. For best results, face the Radar Coach™ so the object flies in as direct a line as possible towards the sensor.
5. There are certain mathematical phenomena that could affect the accuracy of measurement. One of these is the Doppler
Effect that measures the relative speed of an object as it approaches the sensor. The measured speed becomes less
accurate when moved off this direct line. This phenomenon is called the Cosine Effect. While radar guns cannot deliver
100% accurate readings, the Radar Coach™ is sensitive enough for the relative results to stimulate improvement, identify
differences, and create high-performance incentives. Expect a reading within 5% of the actual speed of the ball or object
being measured.
6. The Radar Coach™ emits a radio frequency that may cause interference to radio communications. If the product does
cause a disturbance to radio or television reception, which can be ascertained by turning the Radar Coach™ off and on, we
recommend moving the Radar Coach™ or the device experiencing reception problems.
