Great product - Athlon Optics Rangecraft Velocity Pro Radar Chronograph, 2.4 in Display

Charged it up and took it to a local outdoor range. I set it up next to my old Chrony that I have had for 20 years and compare it. The readings were about the same with a recorded difference of around of 3 to 10 fps. The handgun tested was a Wilson Combat 1911 45 ACP shooting Federal match 185 gr 6 shot string. The rifle tested was a AR 308 platform with a 21 inch match barrel shooting Winchester white box 308, 10 shot string. The readings deviations were around 7 to 20 fps . I think the deviations may have something to do with the oriented distance. The old Chrony was set up approximately 10 feet in front of the muzzle and the Rangecraft was set up next to the gun and slightly in front of the muzzle. I don't think the deviations made too much difference because the fps were well within range of each fired round for accuracy. Reloads may be a different story. Overall, the Ringmaster is accurate, easy to use and had more features such as calculating for bullet energy and power factors.
