BushNell 7x50 Waterproof Fogproof Illuminated Compass Blue 137500

Marine Binoculars for Boaters

Built for open water, these 7x50 binoculars deliver bright, steady views from dawn to dusk. The Porro prism design and fully multicoated optics maximize light transmission for spotting markers, hazards and wildlife. Saltwater corrosion resistance and nitrogen purging keep the internals clear in harsh marine conditions. Ideal for mariners and coastal observers who need reliable optics on the water.

Ready to Use, Check Eye Relief

The binoculars arrive assembled with a non-slip rubber armor that provides a secure grip in wet hands. No tools or alignment are required before first use. The main fitting challenge is eye relief: spectacle wearers may find the exit pupil position tight, so test with glasses on before committing to a long voyage. The hermetic seals and internal nitrogen charge are factory-set and not user-serviceable.

7x Magnification with 50 mm Objectives

The 7x power and 50 mm aperture are fixed; they determine field of view, brightness and stability on a moving deck. This combination suits handheld marine spotting where higher magnification would amplify motion and smaller objectives would dim the image at twilight. Buyers who need variable zoom, compact roof-prism form factor or lighter weight for backpacking should look elsewhere. The 137500 model number identifies this specific configuration.
