When fixed magnification isn't enough, the ACTION ZOOM 10-22x50 lets you dial in exactly the level of detail you need-from wide 10x scanning to tight 22x observation-without swapping optics. The 50mm objectives gather substantial light across the zoom range, and multilayer coatings cut glare and maintain high-contrast, lifelike color whether you're surveying a broad landscape or zeroing in on a distant subject. BAK4 Porro prisms deliver a bright, three-dimensional image with solid depth perception throughout the magnification range. The aluminum alloy body is built for field use, with rubber armor providing grip and shock resistance. A central focus system keeps adjustments quick as you zoom in and out.
