Bushnell H2O 7×50 Porro Binoculars (Waterproof)

Bushnell H2O 7×50 Porro Binoculars (Waterproof)

The dark blue 7×50 H2O Porro Prism Binoculars are ideal for mid- to long-range glassing, especially on the water, where you need to be able to clearly see buoys and navigational markers. This combination of magnification and objective lens size produces a wide exit pupil and long eye relief that, when combined with the generous field of view, helps to reduce the disorientation that is common when looking through binoculars on rough water or rolling seas.

They are outfitted with traditional Porro prisms that allow you to more easily discern the relative distances between two objects in your view and anti-reflection multicoatings that maximize light transmission to deliver bright, sharp, and clear high-contrast views with accurate color rendition and crisp resolution across the wide field of view. To withstand the harsh conditions associated with salt water environments, the chassis is made of corrosion-resistant aluminum and the optical tubes are nitrogen-filled to resist internal fogging and O-ring sealed to an IPX7 waterproof rating.

Optical Performance

• Optimized for marine use, bird watching, and wide-view astronomy
• Moderate 7x magnification helps to produce an ultra-wide exit pupil and long eye relief for enhanced low-light use and easier viewing on rough or rolling seas
• Large 50mm objective lenses boost light-gathering ability for brighter views in challenging conditions, such as at dawn and dusk or in heavy fog
• Traditional Porro prism design offers you a rich depth of field to more easily discern the distance between two objects in your field of view
• BAK4 prisms deliver a round exit pupil, and a crisp and clear image with limited edge distortion
• Anti-reflection fully multicoated optics maximize light transmission while improving color rendition, contrast, and clarity
• 340-foot field of view at 1000 yards

Use and Handling

• Textured and slip-resistant center focusing knob is easy to use even in cold and wet conditions or while wearing gloves
• Right-eye dioptric correction dial helps to compensate for individual optical prescription
• Twist-up eyecups for comfortable use with or without eyewear
• Exceptional 27mm eye relief presents a generous eye box that improves viewing comfort with reduced eye strain
• Ultra-wide 7mm exit pupil will cover pupils when they are fully dilated in low light and ensures the entire scene remains in view without vignetting
