We have outdoor 3D tournaments that range from 30 feet above sea level up to 6,000 feet above sea level. At 6,000 feet, my arrow was about 12" above normal target center at 30 feet. This becomes problematic with a single pin sight where it is difficult to sight in multiple distances. Does anyone know if adjusting the 20 yard distance on the sight and adding the same number of sight marks to longer distances on the sight tape is sufficient to address the changes needed to shoot 30, 40, and 50 yard distances? Thanks.
