Fujinon 7x50 FMTRC-SX Polaris Binoculars with Compass

The Fujinon 7x50 FMTR-SX Polaris Binoculars are equipped with a range of optical and design features that make them an ideal choice for various viewing applications. Designed for use in and around water, they boast waterproof seals, slip-resistant armor, and long eye relief for enhanced comfort. These binoculars are also well-suited for astronomy enthusiasts, offering large objectives that gather ample light and a wide exit pupil that covers fully dilated pupils even in complete darkness, perfect for moon viewing, comet hunting, or wide-field planetary observation. Birdwatchers will appreciate the Porro prism optical path, field flattener lenses, and anti-reflection coatings, ensuring sharp and clear views with accurate colour representation, facilitating the identification of elusive bird 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.

Optical Performance

  • 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 colour rendition
  • Generous 395' field of view at 1000 yards

Use and Handling

  • 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
