[QUOTE="TheLBLman, post: 5444195, member: 1409"] It's actually simply a case of adjusting a variable power scope, in your case a 1.5 - 5x variable scope. You're adjusting the magnification, same as on any other variable scope. Someone just figured out that for different arrow velocities, there was a magnification setting, perhaps it might be 4x or so, where the little aim points will coincide with your point of impact (POI). "Crossbow" scopes have multiple aim points, but there is only a single exact magnification that will make both the 20 yd & the 40 yd aim points hit where aimed. The disappointing aspect of this is that you cannot use your scope as a variable scope, since you must leave it "set" at whatever magnification setting works out. IMO, all these types scopes end up having you with too much magnification when most your targets are going to under 30 yds. If you were actually "choosing" a fixed magnification for shots mostly under 30 yds, but rarely over 40, you might "choose" 1.5 to 2.5x ? The Nikon Bolt is a little different, since it's a fixed 3x scope, i.e. greater field of view than the "variable" crossbow scope. One exception is the Burris Oracle which does allow normal use of its 2 - 7x magnification. Another idea is to just use a low-power shotgun scope, sight it in for 25 yds, and use "Kentucky" elevation for less than or more than 25 yds. This works fairly well out to 30 yds, and you're never at risk of using the wrong aim point, which is a risk with any sight having multiple aim points. [/QUOTE]
