Radar Guns

I found the pocket radar to be a bit unreliable.  We had a lot of scouts at most of our hs games and most of theirs read the same, or within one mph.  Mine would sometimes be higher and sometimes lower. When there are 10-15 guys with the same readings, I'm assuming mine was off.  

Pocket radar is fine if you are lined up with the pitch, and not too far away from the catcher. I have found it reads the same as a Stalker in those conditions, or near enough. PBR has been using them on tripods at some of their Tournaments, which is fine, unless the tripod is moved off to one side or another, at which point it becomes inaccurate. 3-5 mph slower, in some cases, and I've noticed that they occasionally have random bad readings on things like 50' curveballs.

I believe PG was using the Stalker brand for a while. I’ve used my tuning fork on a few of theirs. 2 were right and 1 was off. I’m sure some of theirs have been dropped more than a few times. It is also possible to adjust them for the angle. If you don’t reset it to no angle it will read fast.

I sat right next to a PBR guy with a Stalker Pro in June.  I had my ball coach pocket radar.  They weren't exactly the same always, but it looked as though they were within about 0.5 mph of each other, so mostly negligible.  For the money, they can't be beat.  I will say that mine can be glitchy at times.  Like no reading at all will show up on a pitch when it did for the pitch right before it or it'll say a fastball was 12 mph out of nowhere for just one pitch.  Not perfect, but for the money and what we've gotten out of it, I won't complain.
