[QUOTE="DocUSMCRetired, post: 3093190, member: 85458"] Unlikely. Optical chronographs need perfect lighting to be correct. Ideally, you place them inside a light proof box with special lights. Everything from the angle of the sun, to the clouds can effect the reading. Also the smaller they are, the more precise you have to be in the screen distance. This is why the lab versions are 4 feet long or even longer. When running the smaller ones even the slightest change in distance will change the velocity reading. [/QUOTE]
