Schmidt and Bender Zenith Series 2.5-10x56 Rifle Scopes are the perfect example of a variable power scope with highest light transmission. Features include 13 inches measurement overall, second focal plane reticle positioning, 56mm objective lens for achieving highest light transmission levels, and POSICON system for graphic indication of the reticle's position along with remaining travel within the scope. Some models also have the Flash Dot feature. This is the shortest 2.5 - 10x 56mm scope available in the market and can be effectively used for shooting in poor light conditions.
