The 11-44x50 WP Tactical Angled Spotting Scope features a straight focusing eyepiece system with a side focusing knob for magnification adjustment. It also features an easy to use twist-up eyepiece. The fully multi-coated optics and phase coated BAK-4 prisms deliver impeccably bright and clear views. The scope is 100% Waterproof and Fogproof. The extendable sun-shade is set back in the housing to allow the sun shade to cast a shadow and reduce glare for use in bright sun. Made with textured armor covering, this scope is built to withstand the extreme conditions found in the field. The textured rubber also provides the viewer with a firm grip when moving the scope from location to location.
