Accurate, a fast setup, great app fantastic product - Athlon Optics Rangecraft Velocity Pro Radar Chronograph, 2.4 in Display

I can't believe what a difference.This is made in the chronographing. My old one, it had to be set up just right. The sun had to be going around uranus and you had shoot a 22 through it, just to make sure it was working before you started. This thing is so easy to set up there actually is any setup you just turn it on and you're ready to go.Push a couple buttons. The great thing about it is the app. You can email your results and download them to an Excel file and keep them
Filed for future use. I absolutely loved this thing.It worth, every penny, I highly recommend this. I am so glad that I purchased this. From baseball's slingshots, pellet guns bow and arrows rifles. Pistols, it does it all.
And again, so easy and accurate. Thank you Athlon.
