| Most places that sell by "magnification" are incorrect in the values they give (not entirely sure how they work it out really).
Imagine holding a magnifying glass - if you move it closer to your eye or further away the image will get larger/smaller dependant on the focal length of the lens, which is in turn directly related (I think, its been a while since I did imaging) to the power of the lens. The same principle applies to a lens in a compound scope. Sure Loc have a calculator on their website where you can put in the power and the distance and you will get the magnification, although I don't think this is 100% accurate as the peep sight will likely add some degree of magnification (correct me if I'm wrong). |
