This cool baseball has a built-in speed tracking system. It is named the Smart Ball and can track it's self up to speeds of 120MPH.
The Smart Ball has a built in LCD display which shows the speed of the throw in MPH. It claims to be as accurate as a major league radar gun and can measure speed from 46 feet and from 60'6".
Just one word of advice... You cannot hit this ball with a baseball bat or similar object due to the sensitive electronics sitting inside that would get destroyed.
Smart Ball is available from Amazon and currently costs just short of $17.
