I bought an adjustable yardage sight just prior to hunting season. I would have kept my old one on, but the new one came with a pendulum -- perfect for tree-stands. Anyway, I was sighting it in and was very pleased with it. Dead on accurate! 20yds., 30yds., 35yds., 40yds. What the hell, let's try 70yds.! I never found my arrow. I plan on figuring out how to make it work though. I'll probably try again!
