Posicon adjustment enables you to identify the position of the reticle at a glance: With the indicator in the green range, the reticle is inside the square adjustment range, eliminating any possibility of reciprocal impairment of the adjustment movements. The red range indicates setting reserves that could be used when needed, and at the same warns that use of this reserve precludes use of the full adjustment range in the other direction. This means that the gunsmith or hunter is informed when zeroing in the weapon that there is still sufficient adjustment range available in each direction. A marking with repeatability precision on the scope after a weapon has been aimed is made possible by the silver ring on the relevant turret. On this, the user can add his or her own marks for certain distances or different elaborations (i.e. ammunition fillings).
