Swarovski® SLC Binoculars feature several unique design advantages, making them a great set of binoculars for hunters. Expect a top image thanks to SWAROTOP®and SWARODUR® mulitiple coatings on all air-to-glass surfaces and SWAROBRIGHT® and phase correction coatings on the optimized roof prism systems. The 3-part objective lens helps increase light transmission even more, giving top image quality, even in extremely low light situations. The SLC also features individually adjustable eyecups that quickly retract for eyeglass wearers.
