Even if you can't afford or don't want to pay for a more expensive chronograph, there's at least one far more reliable and consistent brand for "Chrony money," the ProChrono.
I've got a prochrono digital and it's been very reliable. A couple of friends have the same ones they're consistent too. I'm very happy with mine & trust it. The folding ones seem to get roundly cussed, but for the same money the prochrono is very good. I refuse to believe that you have to pay $500 or get one of those that hang off your barrel to get an accurate chronograph.
