Eye relief refers to the distance between your eye and the lens at the rear of the scope that will give you a full crisp view, no dark ring around the edges. Important to know for high recoil calibers to avoid a black eye or worse. Some scopes are single power (3Ã32, 4Ã30 for example) which means no adjustments.
The type of scope you need depends on the kind of target you plan to shoot. If you plan to hunt big game at a distance of around 100 yards (91.4 meters) or less, you won't need a high-power rifle scope. Anything more than 7x or 8x is unnecessary.ome scopes are fixed scopes -- you can't adjust the magnification setting. The number 42 refers to the size of the objective lens: 42 millimeters. The size of the lens will tell you how much light it will be able to transmit to the ocular lens. In general, larger objective lenses can transmit more light.
