  • Fully-multi-coated optics assure maximum light transmission resulting in high quality viewing. Every surface of every element is fully coated minimizing internal glare and flare and giving a bright clear view.
  • Unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronizing the eyepiece movement. This minimizes moving parts and assures these binoculars will function properly and clearly for years to come.
  • Aspherical lens elements, which are critical in compact binoculars, provide exceptional edge-to-edge sharpness. This assures that items on the edge of your field of view are just as sharp as those in the center.
  • Available in 8×25 and 10×25 magnifications.
  • These models feature JIS Class 6 waterproof construction and full-body rubber housing for protection against water and shock.
