The 18x magnification is clearly intended for distant targets. Not to mention that the 3x magnification of the Z6(i) 3-18x50 P (BT) offers you the assurance of a large field of view. With the interaction between HD optics and lateral parallax correction, this rifle scope is intended for long-range shooting.
Its 18x magnification makes the Z6i 3-18x50 P L ideal for long-range shooting. The fine illuminated reticle is perfect for accurate shooting at twilight. Not to mention that the 3x magnification offers you the assurance of a large field of view. HD optics and lateral parallax correction guarantee you a faultless image.
