To me, the launcher was hit and miss. I’m not a great golfer, so I do duff some balls here and there. I’ve had this thing tell me my ball went 150 yards ~ although I hit a ground ball 50 yards. It seems accurate when you strike the ball good. Just wasn’t worth the extra money to tell me how far my ball went when you can track that with almost all golf gps devices these days. The GPS side of the device seems to be lacking feature that other high end devices have. I returned this for a well known GPS only device
