Ideal for their High Country II, Summit Carbon, and Ridgeview Carbon tripods, or any tripod with a 3/8"-16 mount thread, the Vortex Optics Pro Leveling Head is built with a light weight and low profile, so you can lighten your load without compromising performance. It is designed with a standard 1/4"-20 stud for optics, cameras, or video gear with ±9° of leveling capability. Once its integrated bull's-eye bubble level indicates you're good, simply twist the locking collar to set the head where you need it.
