Anyone have an opinion on differences in chronos? I bought a Caldwell ballistic precision chrono for $90 at cabelas. Works pretty well in cloudy weather, lots of errors when it's sunny. I hope it's giving accurate numbers, basing my uspsa PF off of it.
I have the same chrono and had the same problem. I found that the IR sun screens suck up some serous battery power so what I do is tape a paper target over the regular sun screens to make a canopy. Even in the brightest sun light it works without getting an error message now.
