The following video on Bat Exit Velocity is part of the Performance Plus Screening Series. To measure Bat Exit velocity you will need a radar. We suggest the Pocket radar. Its important to use the same radar for all testing to maintain consistency. To measure have the Radar about 4 meters behind the contact point. Its really important to have the radar facing the path of the ball flight (so the radar will be angled slightly upwards.) Take the average of 3 hits.
