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.
