Affordable, full-sized, high-specification binoculars, nitrogen-filled and O-ring-sealed for waterproof, shockproof and fogproof performance. Center focusing gives you a clear view in the least amount of time. Extra-long eye relief of 22.7mm makes them a strong choice for eyeglass or sunglass wearers. Rubber-armored for a nonslip grip and slide resistance on the console even in rough water. These features—plus tough yet lightweight polycarbonate construction—make these binoculars durable enough for everyday use in the wet, rough environments common to sportfishing, trawlers and cruisers. Includes neoprene float strap.Magn. x Objective Lens Dia.: 7 x 50Focus: CenterWaterproof: YesPrism Type: BAK-4 PorroBody Material: PolycarbonateLight Transmission Efficiency: 88%Field of View @1000yds: 378'Eye Relief: 22.7mmCompass: NoRangefinder Reticle: NoWeight: 39oz.Warranty: 25 years limited
