Designed to withstand the rigors of a life lived outdoors, the chassis is constructed of a lightweight and durable aluminum alloy. A black, rubberized armor covers the chassis to help give you a slip-resistant grip - especially in cold or wet conditions, while providing protection from bumps and impacts. The optical tubes are nitrogen-filled and O-ring sealed for fogproof performance when moving through extreme temperature variations, while also making it waterproof to a depth of 10 feet. For long-duration glassing sessions, the BF is tripod mountable with an optional adapter, and twist-up eyecups ensure the perfect eye relief with or without eyewear.
