I bought a Pocket Radar 2 years ago and it has performed exceptionally. I used it exclusively in the PUERTO RICO INSTRUCTIONAL BASEBALL LEAGUE this winter and again it was great as I got many, many inquiries as to its price and how to get one. We played 33 games and our league was 49 days long. During those games, I was using it on our players and at 2 different games the other teams used the Stalker and the Stalker Sport. The Pocket Radar was within 1 MPH on every gunning alongside the Stalkers.
