Celestron 71407 TrailSeeker ED 10 x 42 Roof Prism Binocular, Fully Multi-Coated Lens, BaK-4 Prism Glass – Black

The TrailSeeker ED 10x42mm binocular provides high-level outdoor performance—a perfect choice 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. ED Objective Lenses: Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as colour fringing, a visual defect common in binoculars. TrailSeeker ED delivers edge-to-edge sharpness with excellent colour correction and razor-sharp images. Not all ED glass is created equal. Celestron’s high quality ED glass delivers visibly brighter, sharper images compared to non-ED binoculars. The difference is especially apparent in low light conditions, such as at dawn or dusk. Coatings and Prisms: TrailSeeker ED features fully multi-coated optics and phase- and dielectric-coated BaK-4 prisms. A binocular can be considered “fully multi-coated” when all air-to-glass surfaces are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eye. The Body: 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. Viewing through TrailSeeker ED is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the durable twist-up eyecups. Perfect for a Variety of Uses: TrailSeeker ED features a close focus of just 8.2 feet, making it perfect for viewing birds, butterflies, plants, or other nearby subjects. But this 10x42mm binocular also offers the magnification needed to get great views of distance subjects, plus a wide field of view so you can easily follow them as they move. This versatile binocular is an excellent all-around performer.
