Weaver Grand Slam Binoculars give you all the superb quality of the Grand Slam Riflescope series a binocular. The 45mm objective lenses of Weaver GrandSlam Binoculars gather 15% more light than the standard 42mm lenses, and phase-coated roof prisms produce a sharper image with less glare. Weaver has built these binos with multi-coated lenses to provide you with the brightest images possible. In fact, the light transmission is so superior that Weaver GrandSlam Binoculars give you an extra half an hour of visibility at dawn and dusk compared to standard binoculars. Weaver Grand Slam Binoculars are dry nitrogen gas purged to prevent fogging in the worst conditions. Twist-up eyecups protect ocular lenses while offering you continuous adjustment of eye relief. Rubber armor makes these Weaver Binoculars extremely water resistant, and the ribbed exterior provides a sure grip no matter where you use them. Both come with a neoprene strap and a durable high-quality carrying case.
