Nikon's ProStaff features precise, hand-turn, positive-click reticle adjustments with a one-piece tube. It has multi-coated lenses for 90 percent light transmission, nitrogen-filled and O-ring sealed making it waterproof, fogproof, and shockproof. Included is a BDC reticle that allows hunters to hold dead on at ranges exceeding those previously thought possible. It offers a unique see-through ballistic circles which is an incredible advantage for long range shooting yet allowing for a normal sight picture for shorter range shots where the crosshair itself is the aiming point.
