Nikon 6975 ProStaff 5 20-60x82mm Waterproof Spotting Scopes are durable enough for nearly any terrain. Available in 60mm or 82mm objective lenses, they feature bright multi-coated lenses and an ergonomic lightweight Porro prism design with shock-resistant rubber armoring. Initial scanning is already magnified to 20x. The zooming into the fine detail continues to an intense 60x for observing the chosen object. The Prostaff 109' at 1000 yds 16.9mm straight spotting scopes have a built-in sliding sunshade to eliminate glare in bright conditions. It also keeps dust and rain off in rainy or dusty conditions. The Nikon spotting scope with eye relief angled black features internal surface texturing to minimize reflective light loss inside the scope. They are nitrogen-purged and o-ring-sealed to be waterproof to 3.3' for up to 10 minutes as well as fog-proof.
