Re: Just got my Oehler 35
I have a rediculously complicated system for holding my skyscreens, made by a machinist friend and it works perfectly. Uses two Bogen tripods and special dovetail holders - no measuring required as the screens contact machined shoulders that separate them exactly 2.5 and 5.0 feet apart. In the old days, with my 33 system I used ten foot screen spacing - shot the heck out of screens, used an old surveyors tripod and a ten-foot piece of square tubing.
Big thing is to get the screens in a perfectly straight line with the path of the bullet. You can check this by the numbers given, if you get too far out the computer will print an * which means error. By moving one end a tad up or down the numbers will come lower. The laser gives me really good setups, my numbers are usually less than ten or fifteen fps between the first and second screens.
Always carry an extra battery, a small tape measure to get the correct setup distance from the muzzle, and pen and data book for your records. I also keep one extra screen in my kit in case I blast one. Before I went to the laser I always set the screens up with a small level, not I use it for horizontal only.
Good luck with your new toy!
