Built to take on the harshest conditions, this spotter is a must have for any serious hunter or shooter. It features an incredibly rugged magnesium body that is 100 percent waterproof and fogproof, an oversized eyepiece that provides all-day comfort, and Leupolds Twilight Max HD Light Management System, which helps you see more in less light, while reducing glare in direct light. A built-in 1/4-20 rotatable tripod adapter port makes it easy to mount to a tripod.
