>>> Great topic and post. Long time no hear. Miss your comments on the board. I have a question about the batspeed device I bought from you. Placing it behind the batter, aimed through the ball of a Swing A Way, toward the pitcher I get batspeed ratings 15 or so mph higher than if I place it at the side of the ball facing the batter from the other batters box on a Swing A Way. Which is the best place to put it for accurate readings <<<

Hi Richard

The SwingMate will give you 1mhp accuracy reading when the bat is moving straight at or straight away from the unit. I have found it will retain that accuracy with the unit pointing up to 6 to 8 degrees off center. The readings start dropping off at about 9 degrees at about 2% per degree.

Most batting schools I have visited use the unit with a heavy bag. They mark a spot on the bag and place the SwingMate about 18 inches behind the bag so that the bat-head is coming straight at the unit. This gives an accurate contact velocity reading on nearly every swing.
