Can't go wrong! - Athlon Optics Rangecraft Velocity Pro Radar Chronograph, 2.4 in Display

I’ve used this several times at the range. I’ve used it for 32 grain 22LR at 1,200 fps, 240 grain 44s at 800 fps, 58 grain 243s at 3,500 fps, and 350 grain 458s at1,850 fps. No issues. It provides average and standard deviation, as well as let you see each individual shot with deviation from average. The only downfall is the need to pick a velocity range. And there is very little overlap in the ranges so if you’re over or under by much, no reading.
As for convenience it’s the best. Sets up in less than a minute and it’s out of the way. Extremely easy to use.
It does not give down range velocity nor ballistic coefficient.
