Night Owl's extended-body 5-power night vision monocular (model NOXM50) delivers higher magnification for better image resolution and more accurate identification of distant targets. Employing the latest generation of optics design technology, the XM50 adds extra magnification without a lot of extra weight. And more importantly, this latest optical design does not sacrifice light amplification for added magnification the way older-technology generation-1 products do. Don't make the mistake of buying a competitive high-mag device, only to be disappointed with a dark image. When buying high-magnification night vision, make sure you demand the very latest optics technology.
