Hi quality USA-made (Wyoming) Brunton binoculars with excellent optics and mechanicals, and minor cosmetic flaws from normal use. Strap included as shown. No caps or case. Wide field view; 488 feet at 1000 yards. Original cost-$400. My research indicates that these are gas-filled, but of course I have no way to verify that. There re a few tiny dust particles inside; I've made no effort to remove them and they have no effect on images, which line up perfectly. Selling AS-IS, no returns.
