Steiner 7×50 Commander Marine Binoculars with Compass

Description

Navigate turbulent offshore waterways and plot coastal navigation bearings using the Steiner 7×50 Commander Marine Binoculars with Compass military-grade marine observation system. Combining 7x magnification with large 50mm objective apertures, this Porro prism instrument yields an expansive 421.7-foot linear field of view at 1000 yards (140m at 1000m), an actual angle of view of 8.0 degrees, a massive 7.1mm exit pupil, and an integrated HD-stabilized analog magnetic compass with an electronic LED bearing display for rapid navigational orientation on rolling seas.

The optical system integrates high-density BaK-4 Porro prisms mounted in a floating silicone suspension that absorbs up to 11 Gs of impact, paired with Steiner Diamond-Marine fully multi-coated optical elements and Nano-Protection hydrophobic lens coatings. Built inside a robust Makrolon polycarbonate chassis wrapped in oil-and-salt-resistant NBR Long Life rubber armoring, the housing measures 208 by 160 by 88mm (8.2 x 6.3 x 3.5 inches) and weighs 1180g (41.6 oz). The chassis is pressurized with dry nitrogen gas via two-way valves and sealed for submersible waterproof reliability down to 10m (33 feet). Navigation and handling mechanics feature Steiner Sports-Auto Focus individual eyepiece focusing that maintains sharp focus from 20 meters to infinity, ErgoFlex contoured rubber eyecups, ClicLoc neck strap release buttons, and an illuminated compass powered by an included CR1225 battery.

Key Features of Steiner 7×50 Commander Marine Binoculars with Compass

Built to naval and maritime specifications, this 7×50 Porro prism binocular combines massive low-light photon gathering with an illuminated fluid-damped magnetic compass. The Sports-Auto Focus system delivers constant optical sharpness from intermediate distances to the horizon once set to the user eyes. Its nitrogen-pressurized Makrolon housing, floating prism suspension, and NBR rubber armoring provide survivability across severe maritime environments.

• 7x magnification power paired with 50mm objective lenses producing a bright 7.1mm exit pupil
• Porro prism optical architecture incorporating BaK-4 glass in a shock-absorbing floating silicone mount
• Steiner Diamond-Marine optical coatings delivering high light transmission and contrast in coastal fog
• Expansive 421.7-foot field of view at 1000 yards (140m at 1000m) across an 8.0-degree actual angle of view
• Integrated HD-stabilized analog magnetic compass with electronic LED illumination and bearing reticle
• Sports-Auto Focus individual eyepiece system providing sharp viewing from 20 meters to infinity
• Nitrogen-pressurized Makrolon chassis submersible and certified waterproof to a depth of 10m (33 feet)
• NBR Long Life salt-and-chemical-resistant rubber armoring with ClicLoc quick-release strap lugs

High-Definition Porro Prisms & Diamond-Marine Lens Coatings

The 50mm objective lenses gather extensive photon volume, working with high-index BaK-4 Porro prisms to generate a large 7.1mm exit pupil that fully floods dark-adapted human eyes with light during nocturnal watch shifts and stormy conditions. Steiner Diamond-Marine multi-coatings maximize contrast, cutting through sea haze, ocean glare, and heavy spray to resolve navigational buoys and distant vessel hulls. Exterior lens surfaces feature Nano-Protection coatings that cause water droplets to sheet away rapidly, ensuring an unobstructed visual field in driving seas.

Makrolon Polycarbonate Body & Integrated Fluid-Damped Compass

The Makrolon polycarbonate chassis delivers high structural durability while resisting corrosion from continuous saltwater exposure. The built-in analog magnetic compass utilizes an oversized fluid-damped capsule that stabilizes heading readings on pitching vessel decks, with an integrated battery-powered LED illuminating the compass card for night navigation. Ergonomic ErgoFlex eyecups fold down for use with sunglasses or optical eyewear while shielding the observer eyes from peripheral sea glare and wind.

• Integrated illuminated magnetic compass providing stable bearing readouts on moving vessel decks
• Sports-Auto Focus individual eyepiece adjusters providing set-and-forget optical sharpness to infinity
• Submersible nitrogen-pressurized Makrolon housing resistant to extreme thermal shock and chemical corrosion
