Kurt said:I have been using my dads Pro Chrono. It is an older one with small cueball size holes in these little cards. The bullet passes quite close to the unit so niether one of us has the cohones to shoot through it down range. We have never had a lick of trouble and with things being equal (like temperature) it is very consistant. It shows averages (SD we fugure them) right at what we got in years previous with the same loads, so we have sort of a "test" for the thing. Trajectory is right with book figures for a given bullet at a given speed. I think he has had it for about ten years and I guess what i'm trying to say is over the years it has proved very believeable. Even more so now that I have been able to compare others results here in online BB with fellers that SHoot loads that I or my dad have also shot. I want my own someday and see now the prices are better. I was thinking Chrony because of the upgrade offer.
WHich one do you have Lloyd? and have you thought of upgrading. I hear those are sensitive to shadows. Heard guys say they work better on overcast days & some set the unit in the shade.
