The trackman B1 is the state of the art technology used for pitching and hitting aspects of improving in baseball. This device uses Lasers to detect launch, flight, and other data in order to optimize athletes experience. The device we are selling is lightly used being sold because we have 2 and don’t use this one. New it is going for $18+ with all the extras and comes out to over 20K. We have reduced the price significantly to help cover 1k transfer fee and a 2k license fee through Trackman. We can connect you with someone to figure that out and Trackman will also help you get things set up and running in no time. It comes with a tripod and mount and the carry backpack. Please reach out with any questions.
