The baseball of Brookstone is designed to measure and display the speed of the throw when it is caught. The radar pitch baseball is good for up to 80feet, and 120MPH. The velocity upon impact shows up on the small in built LCD screen.
The ball is of regulation dimensions and weight, however you cannot strike the ball with a bat, or throw against a brick wall I guess.
One LR44 button cell battery is required to operate the ball, which automatically powers off after two minutes of inactivity.
Yeh pretty cool, I’m sure I would break it though…
