Determine how far away your prey is with help from the Vortex Impact 850 6 x 20 Range Finder, which accurately measures distances up to 850 yards away. Using 6x magnification, you can use the range finder to get a closer look, and the O-rings seals are designed to keep out moisture, dirt and debris, so the unit can handle rigorous use in the field. The Horizontal Component Distance (HCD) mode helps compensate for angles, and the unit is waterproof for use in wet conditions. Includes a strap, a lens cloth and a carry case.
