Built to U.S. military specifications for optical performance, waterproofness, and durability, these are probably the very best marine binoculars in the world! In addition to their light enhancing EBC coatings, the Polaris has “flat-field” lenses to prevent distortion and astigmatism from the center to the edges for the best edge-to-edge sharpness of any binoculars available.
The super long 23mm eye relief allows longer viewing without fatigue, and is a critical factor for those who wear glasses. It allows the eye to be further away from the eyepiece without image cutoff. The compass model features a very large, stable and accurate compass and reticle. Binocular weight is 3.3 lbs. (3.4 lbs with compass). The binoculars come with attached lens caps, and a comfortable padded neck strap.
