Ultra Wide Field of View: A 429 foot field of view (8x @1000yds) that is distortion free across the field. This provides a new level of peripheral vision to a binocular in this class. It’s as if the binocular housing simply disappears from sight while in use.Phase Coated Bak4 Prism: Multilayer phase-correction coatings applied to the prism surfaces ensure accurate image contrast and avoid unwanted interference effects. While all our optics have fully multi coated lenses, the Pro Issue extends these coatings to the prisms in order to maximize brightness and clarity from edge to edge.Fully Multi Coated Lens Array: Every surface of every piece of glass inside has multiple coatings of broadband anti-reflective coating. This is key to providing a crisp and color correct image, no matter the time of day or night.Waterproof + Fogproof: Submersible in up to three feet of water and nitrogen sealed to prevent internal condensation. There’s no reason to leave them at home - clean them off without worry.Easy to Use: A refined feel in hand, with a smooth central focus knob, easy to dial in diopter adjustment, and a single hinge adjustment that fits all faces. Works for glasses wearers and those without using our multi step twist up eyecups. Product Description Track Page Views WithAuctiva's Counter
