The Zulu6 binoculars have Optical Image Stabilization by way of the prism being electronically stabilized by a 2 axis gimbal. This compensates for human motion input into optics allowing for handheld use of high magnification optics, eliminates shake due to buffeting winds, heavy breathing after a long hike, cold induced shivering, washboard ranch roads, and chop on the water. The Motac system conserves battery life by turning the unit off after 5 minutes of no motion.
