Have you wondered what night vision technology is all about? American Technologies Network Corp. makes night vision devices for military, law enforcement and security purposes. It’s new Night Trek 3X Monocular is an affordable, entry-level unit perfect for fooling around in the backyard or at a campsite. Water- and fog-resistant, it has a built-in infrared illuminator. Powered on 3V (CR 123A) batteries, the Night Trek runs up to 30 hours. While the company says the effective detection distance is up to 200 yards, we found it most useful at distances of 50 yards or less. Within that range, performance was excellent. The ATN Night Treks come with instructions, lens tissue, battery, lens cap, and warranty card all in a soft carry case. $219 www.atncorp.com —Shawn Perich
