By moving up to the BX-2 Alpine HD 10x52mm, you increase the amount of light getting to your eye, which is great for low-light conditions. Whether it's your first binocular or your 50th, your glass needs to give you a bright image, feel comfortable in your hands, and be able to take a beating. Now available with high-definition performance, the BX-2 Alpine HD binocular checks all of these boxes and more. Built around Leupold’s Advanced Optical System, it offers tried and true light transmission for extended glassing sessions, best in class glare reduction in harsh light, and the resolution and clarity that recreational sportsmen and sportswomen demand.
