These Fujinon 7x50 FMTR-SX Polaris Binoculars are outfitted with a suite of optical and design elements that make them an ideal optic for a variety of glassing applications. For those jobs on and around water they feature waterproof seals, slip-resistant armor, and long eye relief. For astronomers who like to view the moon, hunt for comets, or enjoy wide-field viewing of planets, the large objectives gather buckets of light while the exit pupil is wide enough to cover fully dilated pupils in total darkness. Birders will appreciate the Porro prism optical path, field flattener lenses, and anti-reflection coatings that ensure crisp and clear views with accurate color representation for positive identification of elusive species.
These binoculars have a built-in compass with maximum error of ±0.5°. The scale can be used to identify the object's direction, measure distance, and determine the size of a target object. The compass is global, accurately measuring direction in both northern and southern hemispheres.
- Optimized for marine use, bird watching, and wide-view astronomy
- Moderate 7x magnification helps to produce a wide exit pupil and long eye relief for enhanced low-light use and easier viewing on rough or rolling seas
- Large 50mm objective lenses boost light-gathering ability for brighter views in challenging conditions such as at dawn and dusk or in heavy fog
- Traditional Porro prism light path presents a rich depth of field to discern the relative position of objects within the field of view
- Integrated field-flattener lenses eliminate distortion at the edges of the field view for a more immersive experience
- Anti-reflection EBC fully multicoated optics boots light transmission to 95% for brighter high-contrast images with accurate color rendition
- Generous 395' field of view at 1000 yards
-
- Integrated global compass for ranging, navigation, target size estimation
- Individual focusing eyepieces ensure the sharpest views possible for every user
- Fold-down rubber eyecups contour to the eye socket and block peripheral light from affecting the view
- 56-74mm interpupillary adjustment range
- Exceptional 23mm eye relief presents a generous eye box that allows the optic to be held away from the face, prevents accidental impacts on rough seas, and makes viewing more comfortable with reduced eyestrain
- Wide 7.1mm exit pupil allows you to enjoy the entire view without vignetting, even on rough seas
- Impact-resistant chassis meets milspec standards
- Protective rubber armoring provides a slip-resistant grip, especially in cold and wet conditions
- Nitrogen filled and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions
- O-ring sealed, submersible to a depth of almost 7' for five minutes
- Broad -4 to 122°F operating temperature range
- Tethered objective lens caps and ocular rainguard prevent loss during observation sessions
