This is the best one on the market!! It was very accurate. I am a manager of a baseball team and I love this pocket radar. It work great for the pitching machine set up, batting cages and for the kids pitching. It is a item every ball player should have!!! Very easy to use!! If you need a speed radar gun , buy this one , you will be happy you did !!! The service i recieved from the president of the company was outstanding!!!!
