The dark blue 12x42 H2O Porro Prism Binoculars are ideal for long-range glassing, especially on the water, where you need to be able to clearly see buoys and navigational markers even in low or fading light. Bushnell built them using ecologically friendly glass that is manufactured without lead to be better for the environment.

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

• High 12x magnification allows users to make detailed observations of distant objects such as buoys and navigation markers
• 42mm objective lenses boost light-gathering ability versus compact models for improved low-light performance without the bulk of larger objectives
• 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
• Wide 61¬∞ apparent angle of view presents an immersive observational experience without the need for a lot of side to side head movement that also minimizes the appearance of the distracting hand-shake
• 267-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
• 14mm eye relief improves viewing comfort with reduced eye strain
