Product Description

The Fujinon 7x50 FMTR-SX Polaris Binoculars are designed with advanced optical and structural elements, making them a versatile choice for various viewing applications. Whether used for marine navigation, birdwatching, or astronomy, these binoculars offer waterproof sealing, slip-resistant armor, and long eye relief for comfortable extended use. Their large objective lenses maximize light intake, providing bright and clear images even in low-light conditions, while the wide exit pupil ensures full coverage of dilated pupils in complete darkness. The Porro prism optical path, field flattener lenses, and anti-reflective coatings deliver crisp, high-contrast visuals with accurate color reproduction, making them ideal for spotting distant objects with precision.

These binoculars also feature a built-in global compass with a maximum error of ±0.5°. The integrated scale allows users to determine direction, measure distances, and estimate target sizes. Because the compass functions accurately in both hemispheres, it ensures reliable navigation worldwide.

Optical Performance

• Optimized for marine use, birdwatching, and wide-field astronomical observations.
• 7x magnification provides a wide exit pupil and extended eye relief, enhancing visibility in low-light environments and ensuring stable viewing on rough waters.
• Large 50mm objective lenses improve light-gathering capability for bright, detailed images, even at dawn, dusk, or in foggy conditions.
• Porro prism optical design enhances depth perception, allowing users to determine object distances more effectively.
• Integrated field-flattener lenses eliminate distortion at the edges for a more immersive viewing experience.
• EBC fully multi-coated optics increase light transmission to 95%, producing sharp, high-contrast images with true-to-life colors.
• Expansive 395-foot field of view at 1,000 yards for capturing broad scenes with ease.

User-Friendly Design

• Integrated global compass assists with navigation, range estimation, and object size measurement.
• Individual eyepiece focus adjustment ensures precise clarity for each user.
• Fold-down rubber eyecups provide a comfortable fit while blocking unwanted peripheral light.
• Adjustable 56-74mm interpupillary range accommodates different eye distances.
• 23mm long eye relief reduces eyestrain and allows comfortable use, even while wearing glasses.
• A 7.1mm exit pupil ensures a bright, uninterrupted field of view, even in motion.
