Explore deep seas with the floating and waterproof Barska 7x50 WP Deep Sea Floating Binoculars. These truly marine binoculars feature all the right characteristics that you find in nautical binoculars beyond their class: a Porro prism design for an enhanced perception of depth, a compass and a rangefinder for making your measurements, individual focusing, and an O-ring sealed nitrogen fill for fogproofing. In addition to the clear and bright fully multicoated optics with large objectives and a long 23mm eye relief, these binoculars also provide an ergonomic housing with a thick layer of rubber armoring to ensure a secure grip and impact resistance. To protect the lenses when not in use, the binoculars also has a set of tethered lens covers.
