The powerful Barska 20-140x80 Gladiator Zoom Binocular has been designed specifically for long-distance terrestrial and astronomical viewing. The 20-140x magnification range allows the viewer to scan a large field of view and then zoom in on the selected object for a closer look. A zoom thumb-lever allows the user to quickly zoom in or out without having to take their eyes off of the binoculars. Large 80mm objective lenses help increase light transmission in low light conditions to deliver a stunning view day or night, and the Gladiator's multi-coated lenses and BAK-4 prisms provide optimal clarity for enhanced detailed viewing. The Barska 20-140x80 Gladiator also features a sturdy mounting brace that allows the user to attach these binoculars to a tripod (not included) for a stabilized viewing experience.• Multi-Coated Optics• Braced-In Tripod Mount• Protective Rubber Armor Coating• Fold-Down Eyecups• BAK-4 Porro Prisms• Soft Carrying CaseSpecificationsModel Number: AB11184Focus System: CenterPrism Type: PorroPrism Glass: BAK-4Magnification: 20x - 140xClose Focus: 87'Eye Relief: 21 mmObjective Lens: 80 mmExit Pupil: 4 mmField of View @ 1000 yds.: 54' @ 20xOptical Coating: Multi-CoatedWaterproof: NoFogproof: NoWeight: 70.4 oz.
