The 8x42 TrailSeeker ED binocular provides high-level outdoor performance—a perfect compact ED binocular for avid birders, hunters, and outdoor enthusiasts. TrailSeeker ED is packed with optical, mechanical, and ergonomic features that make it comparable to binoculars costing two to five times as much. Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual defect common in binoculars. TrailSeeker ED delivers edge-to-edge sharpness with excellent color correction and razor-sharp images. TrailSeeker ED also offers fully broadband multi-coated optics and phase- and dielectric-coated BaK-4 prisms. Taken together, these features maximize light transmission for the brightest, most detailed images possible. TrailSeeker ED is composed of lightweight and durable magnesium alloy. Its tough, rigid frame is coated with rubber to stand up to hard use in the field. What’s more, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. TrailSeeker ED includes both a neck strap and a carrying harness so you can choose the option that’s most comfortable for you. It’s also tripod adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping sessions. The binocular also includes a protective soft case for storage or transport.
