As part of Hawke's Endurance ED binocular series, these binos are perfect for viewing wildlife, action and sports. They're ready to go on your next adventure, offering compactness, portability and a tactile feel. The lightweight polycarbonate chassis is impact, corrosion and temperature-resistant, and features a slip-resistant rubber armouring around the outside to further protect the internal structure. Speaking of which, this series of binoculars have an advanced lens structure that includes the use of specialised ED glass that reduces chromatic aberrations, anti-reflection fully multi-coated optics for improved image and high-quality phase-corrected BAK4 roof prisms that provide improved contrast and colour fidelity. Seeking out your inner adventurer, these binos are nitrogen-filled which makes for effective water and fog-proofing. These binos are made for any time, anywhere, any weather.
