This is a long range forum. That doesn't mean you have to be into long range to be a member. Or take advantage of all the info that's available. Is a chrono necessary, probably not. But if a person is trying to get into long range (say 500 yards and beyond) personally I can't imagine not having a chrono. I use the magneto speed, I'm sure there are better but find it to work quite well. Good luck with your new build, enjoy have fun and be safe.
