[QUOTE="DougMH, post: 702917, member: 26282"] The only one I trust completely is the Oehler 35p because it's basically 2 chronographs in one. I suppose you could use 2 chronographs from another mfgr in line. While it's adjustable, the default for the primary chrony is 4'. The proof chrony is at 2' (in the middle). When you shoot, you get a reading from both the primary and the proof. If they're within tolerance, you're good to go. If they're too far apart, an * prints to the right of both readings and that reading is not in the calculations of ES, SD, Max, Min, Mean. Again, you could do the same with 2 chronys, but you'd have to make the comparisons manually. [/QUOTE]
