Waterproof Binoculars Don?t Have to be Expensive! Bresser Condor Series Binoculars come in a nice selection of sizes, from the compact yet rugged 32mm models to the larger aperture, super bright 42mm designs. All models are waterproof, have rugged roof prisms, twist-up eyecups, diopter compensation, and are made with BK4 barium-crown glass that is fully multi-coated. The medium-sized Condor 42mm binoculars, available in both 8x and 10x, are perfect for birders and nature lovers, and make a great all-around binocular for most anything you can throw at it. The larger optics play nice with sunrise and sunset scenes as well as brightly lit sporting events. Waterproofing keeps them safe against leaking water bottles, trips aboard a vessel, or even living along the coast, where fogging and fungus can be an unwelcome result of beach life. The twist-up eye cups make adjustments easy for those who wear eyeglasses. For situations when greater stability is desired, the Bresser 8x42 and 10x42 models have a tripod thread. end tab Specs Item Number 18?21042 Magnification 10 Field of View 101m/1000m Waterproof Yes Lens Coatings fully multi-coated Eye Relief 42mm Exit Pupil 4.2mm Focuser Type center Dimensions 150x135x55 mm Brightness 17.64 Objective Lens Diameter 42mm Apparent Field 5.8?
