The Oberwerk MRF (Multi-Reticle Finder) projects an easy-to-see reticle, focused at infinity, that is selectable between 4 patterns (shown below), in 2 colors (red and green), with continuously-variable brightness using a large easy-to-operate dial. The reticle can be seen from as close as a couple inches to more than a foot from behind. Steer the binocular so the reticle pattern is on your target, then when you look through the binocular eyepieces, your target will be in the middle of the field of view. The MRF mounts directly to the XL Series Picatinny rail handle. Optional machined-aluminum dovetail adapters are available for use with the Oberwerk 20×80 Deluxe III and 25x100Deluxe. Also compatible with the FAR-Sight Mounting System. CR2032 lithium battery included.
