The compact and lightweight navy 8x21 U-Series UP Binoculars combine aspherical optical elements and BAK4 Porro prisms to deliver edge-to-edge image sharpness with a 50° angle of view. The optical elements are also fully multicoated to provide a high transmission of light. With an 8x magnification and 21mm objectives, you obtain a notable magnification, insignificant image jitter due to unsteady hands, and a compact form factor. You can easily spot your targets with a wide 6.2° angular field of view and quickly bring them into focus with a center focus wheel. In addition to observing distant scenes, birds and game, the minimum focus of 9.2' allows you to study in detail close objects like animal footprints, marks or landscape features. The binoculars also feature a 2.6mm exit pupil, a 13mm eye relief, an interpupillary and a diopter adjustments. The binoculars are very compact, lightweight, and features a single piece frame that houses objectives, which allows for a synchronized interpupillary adjustment. To accommodate glass wearers, the binoculars offer sliding rubber eyecups. Also included are a carrying case, a neck strap, and eyepiece covers.
