The ECO Eagle ED II FF APO 10x40 binoculars are the lynchpin of our new flagship binocular range. With simple, yet effective improvements on what was already a fantastic design and a vastly improved optical performance thanks to flat field, apochromatic, ED glass lenses made by HOYA in Japan. The fundamentals of a great binocular are already in place from the rest of our high performance East Coast Optics range; a minimalist design, waterproof magnesium body, class leading optics, and high strength rubber armouring. The design has been improved via a custom made chassis for low weight but high strength, ensuring they are shock proof to up to 2 metres. This ensures the ECO Eagle ED II FF APO 10x40 binoculars are ready for any birding adventure. High quality HOYA glass with FMC hydrophobic coatings and Bak4GT prisms with HR dielectric and phase coatings ensure a sharp image right across the frame to enhance viewing pleasure. A huge 17.2mm eye relief makes these binoculars fantastic for glasses wearers and a close focus of just 2 metres offers a brilliant option for insect and reptile observation. The 2026 Eagle II range take these qualities and add a class leading field of view to all models within the range. All Eagle II binoculars are fully waterproof, come with a lifetime warranty and a high quality case, rainguard, objective covers, and neoprene strap. Why we love them. "The 40/42mm binocular market has so much choice on offer. The new Eagle ED II FF APO 10x40 binoculars offer the highest performance optics and lightest weight of any binoculars at their price point. We love them and we know you will love them too."
