The Swarovski ST Balance 14-35x50 Spotting Scope provides handheld clarity without the shake. The ST Balance offer razor-sharp views. Using mechanical stabilization, it compensates for image shaking caused by hand movements. The image stabilization allows for the freedom to hold the scope in your hand, unlike traditional spotting scopes. The integrated gyroscope sensor measures the current movement of the spotting scope. The advantage of the Balance spotting scopes is that even at the highest magnification, this optical still offers an effortless viewing experience with a natural sense of vision, even when handheld.
