When setting up the 35P (or any other light-screen chronograph) I use the method suggested in the directions, I believe written by Ken Oehler himself:
Set up your rifle on bags, aimed at the downrange target you'll be shooting. Then, with the rifle unloaded and bolt open, set up the chronograph, aligning it while looking over the screens at the muzzle/scope of the rifle. This is quicker than any other method I've tried.
Never read the instructions, a talent I learned from my wife, but I always set up my 35P that way, always taped the wires together, always put different colored tape on each wire and that helps set the front to the front and the rear to the rear and other thing I always do, is put a couple of long sand bags across the main beam to hold the balance, which also assists when a breeze pops up.
After having 2 over the years, I have no interest in looking further. That;s a Baby Boomer disease I am comfortable with. The shopping is done.
