The Nikon ProStaff binoculars have ‘successful hunting' written all over them. These little beauties feature the same waterproof, fogproof and shockproof performance as their big brothers in the Monarch and Action Extreme series. Rubber armored for a sure grip, the Nikon ProStaff integrates bright, multicoated lenses, BaK4 high index prisms and turn and slide eyecups.
