Swarovski NL Pure 8x42 Binoculars have the widest field of view of any 42mm binocular - 477' at 1000 yds! They have all of the Swarovision features of the ELs in a rubber armored body designed with slimmer tubes to optimally position your hands for long term viewing. Close focus is 6.6' and it takes less than 2 full turns of the focus wheel to get there from infinity. Light transmission is 91% from end to end. The NL Pure's eye relief is 18mm, and field flattener lenses in the eyepiece assembly provide a virtually distortion-free view. The strap and lens coverings attach in the same manner as the EL Pro models, but the case newly designed to make access easier. Also included with each NL Pure binocular is Swarovski's Universal Comfort Strap, a microfiber cloth, and a soap and brush kit for cleaning the rubber armor! Of course, the NL Pure binoculars are waterproof and nitrogen purged to be fog proof.
