Shepherd Rifle Scope gives you the best of both worlds with the drawbacks of neither. Shepherd uses the front focal plane location for range finding and bullet drop compensating circles. This gives Shepherd Scope the German dependability and, when zoomed, the circles do not block the targets but instead frame them and give you instant target engagement on any power. Then put the cross hair in the rear focal plane (where the Americans do) in order to get the benefits of a non-magnifying reticle. This patented Dual Reticle System lets each reticle monitor the other and thus allows for: one shot zeroing in, "at a glance" verification of the original zero, and visual confirmation of windage and elevation adjustments before you shoot. The Shepherd is truly the most reliable of all and the only one to tell you if something is out of zero before you shoot.
