Carl Zeiss VM/V 1.5-6x42mm T In true European tradition, this Zeiss scope is built around a 30mm main tube. What’s new and different in the VM/V model is a redesigned optical system, which results in a scope that is more compact and 20 percent lighter than its predecessor. The 72-foot field of view at 1.5X is ideal for whitetail deer and other game in thick cover.
