About Roof Prism Binoculars:
The prism system of a binocular reduces the size needed to contain a long optical path and turns what would be an upside-down image right-side-up. In roof prism binoculars, the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, streamlined shape in which the lenses and prisms are in a straight line. Roof prism binoculars are less bulky and more rugged than an equivalent porro model.
Boasting Nikon’s fully multicoated optical system and a huge 50mm objective lens, the tried-and-trusted ProStaff 3-9×50 riflescope keeps you hunting as late as possible. The scope’s optical system transmits up to 98 percent of available light, ensuring maximum brightness in low-light, low-contrast hunting situations. To simplify field adjustments, Nikon also integrated a zero-reset turret into the riflescope. Just sight in as usual, lift the spring-loaded adjustment knob, rotate to your “zero,” and re-engage. Field adjustments are now as simple as dialing in your subsequent ranges. And hunters will love the patented BDC reticle, which allows them to hold “dead on” at ranges exceeding those previously thought possible. The BDC’s unique see-through ballistic circles offer an incredible advantage for long-range shooting, yet allow a normal sight picture for shorter-range shots where the crosshair itself is the aiming point.
Nothing boosts a shooter’s level of confidence better than generous, constant eye relief, which is why Nikon provided 3.6 inches of eye relief in the ProStaff. No more rough kickback from heavy recoiling cartridges, lightweight rifles, severe shooting angles, and just plain excitement. Other features include a nitrogen-filled, O-ring-sealed housing that’s waterproof and fogproof; support for an optional sunshade accessory for bright, rainy, or dusty conditions; and a quick-focus eyepiece. Offering enough power for the longest shots and a wide field of view for thick brush or timber, the ProStaff riflescope carries a lifetime warranty.
