Fujinon 7×50 FMTRC-SX Polaris Binoculars

Description

Engineered with a built-in compass and field-flattening optics, the Fujinon 7×50 FMTRC-SX Polaris Binoculars delivers a 394.6-foot field of view at 1000 yards (7.5-degree actual). The large 7.1mm exit pupil and 23mm eye relief stabilize rolling deck views. A distant 32.2-foot close focus prevents near-range dockside inspection or backyard birding.

Field flattener lenses combine with BaK-4 Porro prisms treated with proprietary Electron Beam Coating (EBC) multi-layers and an illuminated precision compass. The cast-aluminum chassis is wrapped in thick blue-gray rubber armor, measuring 8.6 by 7.8 by 3.1 inches at 3.1 lbs (1.4 kg). Nitrogen purged and waterproof to military specifications, it features individual eyepiece helical focusers, fold-down rubber eyecups, and front tripod adapter threading.

Field Flattener Optics & Low-Light Transmission

Fujinon’s field flattener elements eliminate astigmatism and peripheral distortion, preserving razor-sharp image quality right out to the field stops. The massive 7.1mm exit pupil matches dark-adapted human eyes in starlight, while EBC multi-coatings channel maximum light throughput to reveal unlit buoys in pitch-black conditions.

Individual Focus & Marine Armor Mechanics

Independent helical focus collars let you calibrate each ocular once to infinity, eliminating focal slippage from vessel vibrations or rough transport. The thick rubber armor deadens contact noise against boat consoles, and the nitrogen-pressurized aluminum housing resists saltwater corrosion over decades of use.

• Individual eyepiece focus system holds permanent focus from 30 meters to infinity
• Nitrogen-filled seals prevent internal lens condensation during sudden marine temperature drops
• Internal compass card features battery-powered night illumination for 24-hour navigation
