The Barska 20-60 x 60mm WP Blackhawk Straight Spotting Scope features a straight eyepiece system and wide zoom range to see objects in greater detail. The multi-coated Porro lenses maximize light transmission and offer bright, clear, high contrast views in all types of lighting and weather conditions. Other features include an O-Ring seal for 100 percent waterproof and fogproof protection and an extendable glare-reducing sunshade, which is set back in the housing to allow the sunshade to cast a shadow and reduce glare for use in bright sun. The large objective lens increases light transmission, delivering brighter images in low light conditions. The Barska 20-60 x 60mm WP Blackhawk Straight Spotting Scope is convenient and portable with a sleek go-anywhere compact body.
