[QUOTE="johnnyk, post: 1760306, member: 307"] I started out using one years ago. I didn't know it then but have since learned that once you unfold it, make sure it flat (fully open) and that it is level and parallel with the barrel of your rifle. By that I mean you don't want your bullet crossing 7.5" over the front sensor and 6" over the rear sensor. Or over the right side of the front eye and the left side of the rear eye. I think it's calibrated to be the same distance over each sensor and parallel with them. Also, if you don't have a light kit and using ambient light, the sun gets low and not enough light reaches the sensor or hits it at low angles you get errors or exaggerated readings. I've owned/used a couple different optical sensor type chrono's over the years (probably like half the members on here) and the first chance I got I went with the LabRadar. It's pricey but I think worth every dime.
