Swarovski 12×50 EL50 Binoculars with FieldPro Package (Green)

Description

Overcoming long-distance heat mirage and resolving distant big-game antler points across open western canyons, the Swarovski 12×50 EL50 Binoculars with FieldPro Package (Green) deliver high-magnification optical clarity and extended reach for demanding backcountry hunters. Pairing a high-power 12x magnification with light-gathering 50mm objective lenses, this premium roof prism instrument yields a 300-foot linear field of view at 1000 yards (99.6m at 1000m), an actual angular view of 5.7 degrees, a 4.2mm exit pupil, and a forgiving 19mm eye relief that accommodates eyeglass wearers during extended glassing sessions from canyon rims and elevated ridges.

The optical system features field flattener lenses integrated with fluorite-containing HD glass elements and phase-corrected roof prisms treated with Swarobright, Swarotop, and Swarodur multi-coatings, supplemented by Swaroclean non-stick external lens coatings. Housed inside a rugged magnesium alloy chassis wrapped in ergonomic dark green rubber armoring, the binocular measures 17.5 by 13.2 by 6.6cm (6.9 x 5.2 x 2.6 inches) and weighs 992.25g (35 oz). The optical barrels are nitrogen gas purged and O-ring sealed for waterproof submersion down to 4m (13 feet). Field handling centers around an open-bridge wrap-around grip, a smooth center focus wheel with a 9.2-foot (2.8m) minimum close focus distance, an integrated locking diopter adjustment dial spanning -4 to +4, four-position twist-up click-stop eyecups, an interpupillary range of 56mm to 74mm, and the FieldPro rotating strap attachment system with tethered objective covers.

Key Features of Swarovski 12×50 EL50 Binoculars with FieldPro Package (Green)

Designed for open-country hunting and precision long-range scouting, this 12×50 roof prism binocular combines Swarovision field flattener optics with high-density fluoride glass elements. Its nitrogen-sealed magnesium housing provides full waterproof protection in severe alpine conditions. The FieldPro strap connector system and integrated push-in objective covers ensure silent, secure handling across steep mountain ascents.

Swarovision Field Flatteners & Fluorite HD Glass Optics

The Swarovision optical formula utilizes field-flattening lens groups that correct spherical aberration and field curvature, providing sharp resolution from the optical axis out to the very periphery. Fluoride-containing objective lens elements eliminate color fringing and secondary chromatic aberration on high-contrast edges, such as skylined elk on alpine ridgelines. Proprietary Swarobright prism dielectric coatings deliver greater than 90% light transmission, providing rich color contrast during the critical 15 minutes before sunrise and after sunset.

Magnesium Open-Bridge Chassis & FieldPro Hardware Integration

The dual-bridge open-hinge architecture allows fingers to wrap completely around the optical barrels, maintaining a steady, balanced grip during high-power hand-held observation in gusty mountain winds. The central focusing wheel rotates with fluid, balanced resistance, housing an integrated pull-out diopter ring that clicks securely into position to prevent accidental focal shift. The FieldPro hardware system replaces standard strap loops with 360-degree rotating bayonet pins that allow the neck strap to pivot naturally without twisting during rapid shoulder transitions.

• Central focusing mechanism with integrated pull-out locking diopter ring calibrated from -4 to +4
• Impact-resistant magnesium alloy housing finished in protective non-slip green rubber armoring
• Multi-stage twist-up eyecups with tactile click-stops and 360-degree rotating FieldPro strap connectors
