The Mark 4 20-60x80 Tactical Spotting Scope from Leupold embodies the full range of Leupold's advanced optical technologies and packs them into an armored magnesium alloy body that is both lightweight and easy to handle. Leupold outfitted this Mark 4 series scope with their Xtended Twilight Lens System, which combines High-Definition (HD) glass and several specially engineered optical coatings to improve twilight performance. This model also has a Mil-Dot reticle that can help the spotter calculate their target range or size at any of the scope's magnification settings.
Leupold's HD lenses are made of high-transmission, calcium-fluoride glass elements that produce saturated colors and clarity that is superior to that of standard optical glass. Additionally, HD elements are lead-free, and they weigh less than comparably-sized standard glass elements. The Mark 4 optical path is enhanced by phase-corrected BAK4 prism glass and index matched lens coatings. Each lens surface is multicoated with an index matched coating that is optimized to suit the refractive index, function and placement of the lens. Leupold also employs their Multicoat 4 anti-reflective lens coating to maximize the light gathering ability of the lenses. The resulting images are detail-rich, with luminous and color faithful views.
Complementing its high-definition optical system, the Mark 4 Tactical scope has handling features that deliver a user-friendly glassing experience. Rubberized ridges on the zoom wheel and a textured focus dial provide tactile feedback that is especially useful when making field of view adjustments in wet conditions or while wearing gloves. The scope's eyepiece has a fold-up/down rubber eyecup and 30mm eye relief that provides a comfortable viewing distance even for eyeglass wearers. This Mark 4 scope is compatible with an optional digiscoping adapter that allows the viewer to capture the transmitted image using their digital camera.
The Mark 4 Tactical also comes with a ballistic nylon protective case designed to stay on the scope yet permit fast access to the scope's eyepiece, zoom and focus controls. This stay-on case includes a shoulder strap, and the case features zippered access with quick-access panels that fold out to provide unobstructed access to the eyepiece.
In addition to being lightweight and easy to handle, its nitrogen-filled housing makes the Mark 4 ready to endure heavy rain and extreme humidity. A folded light path gives this scope a remarkably compact footprint—especially for a large-objective optic. This combination of functionality, build quality and image quality make the Mark 4 Tactical lineup ready for almost any long-range targeting and viewing task.
