Many consider a 10x42 binocular to be the sweet spot for glassing. It offers enough magnification for clear identification, but is still compact enough to take everywhere.

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. The BX®-2 Alpine 10x42mm binocular checks all of these boxes and more. It’s perfect for any glass-and-go scenario. With our Twilight Max® Light Management System, this binocular will out-perform everything in its class when it comes to seeing more in less light. And like all Leupold binoculars, it's guaranteed for life.
