Features of this binocular . . .
Roof prism optics. H-body roof prism design with internal center focus. High quality BaK-4 prisms for unrestricted light transmission.
Multicoated optics. Multilayer antireflection coatings for good light transmission, color fidelity, and image contrast. With a 2.5mm exit pupil, it does its best work in well-lighted environments, rather than in shadowed woodlands and twilight situations.
Waterproof and fogproof. Dry nitrogen filled and O-ring sealed to be waterproof and fogproof in all temperature and climate extremes. Designed to operate reliably in rainforests and deserts alike.
Armor. Black rubber armor absorbs noise and the bumps and thumps of everyday use and provides a good grip when wet.
Wide field. The field of view is 6.3° (330' at 1000 yards), as much as a degree and more wider than most other high power binoculars in this power and aperture range.
Twist-up eyecups. The rubber-rimmed eyecups extend to block ambient light and increase contrast for those who don't wear glasses. They retract for eyeglass or sunglass use. Eye relief is 10mm, so there will be some vignetting for those who must wear eyeglasses when observing.
Fast focusing. Little more than three-quarters of a turn of the ribbed rubber focusing knob moves from a near focus of 17' out to the horizon and beyond. While a 17' close focus is not designed for close-in birding, it is more than acceptable in a binocular designed for long distance observing across marshes and meadows like this 10 power Outland X.
Rotary diopter correction. A variable diopter ring on the right eyepiece allows you to match the binocular optics precisely to your individual eyesight for a sharp image.
Standard accessories. A one inch wide woven neck strap for comfortable all-day use and a Cordura-style nylon carrying case with a belt loop for no-hands carrying are standard equipment.
