Just received a Labradar and took it out for a trial. Didn't have much centerfire to shoot, but a friend had his 9mm Luger. The 9mm was tracked consistently and velocities seemed reasonable. But, I had a lot of difficulty with detection failure on 22LR and air riffle pellets. Detection failure wasn't terribly surprising as the 22 & 17 cals are small, but I am very puzzled and disturbed by the extreme velocity spreads reported.

There appear to be a lot of detections but of course, the non-detections do not show up. This happened first time and I figured I just didn't have things set up right and didn't have any external triggers. Received a recoil trigger and an air rifle trigger, but these did not seem to make much difference in the detection rate and made no difference in the extreme velocity variation. Image is from my latter session.
I plan on shooting some centerfire rifle with it, but things are a bit crazy busy right now and this Spring has been very wet and cold, so haven't gotten back out.
I read some of the prior threads on the Labradar, but didn't see any issues like this. And, I haven't contacted Labradar on it yet either.
