  • 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.
  • Offering a user-selectable magnification from 8 to 16 times.
  • The UP 8-16×21 Zoom is offered in unique, attractive colour options that match your personal style.
