10x50 Marine Binoculars | Blue | IPX7 Waterproof, BAK4 Prism, Illuminated Compass & Rangefinder for Boating & Hunting

Built for the Water — 10x50 IPX7 Marine Binoculars in Blue

When you're out on the open water, you need binoculars that can take a beating — and keep working. These 10x50 marine binoculars are rated IPX7, meaning they're fully submersible, not just splash-resistant. Pair that with nitrogen-purged fogproof construction, BAK4 prism optics, FMC-coated lenses, a built-in illuminated compass, and an internal rangefinder, and you've got a serious piece of gear for boating, fishing, hunting, and any outdoor adventure.
