Rugged and reliable on deck and off. Buoyant, waterproof and corrosion resistant. So even if they take a dive, the rock-solid Marine Porro Prism 7x 50mm workhorse still performs good as new. Ultra-bright, crisp views are built in with their fully mulit-coated optics and premium BaK-4 prism glass. And the best part is, the rugged rubber armor absorbs shock and gives you a sure grip in extreme nautical environments.
