This picture shows the setup for picking up the swing speed reading. The ruler on the ground is 18" long.  So I have the radar placed about 10" from the ball at about a 45 degree angle. to my target line.

This picture shows the setup for picking up the ball speed reading. I have the radar placed about 24" from the ball.  You aim right over the top of it so that it makes for a good aliment to your target.

This is just another angle of the above picture. You can see that the radar is laying flat on the ground.. It is only about 1" thick.

The pictures aren't the best but is 19 degrees outside with a 20 mph wind.
