Bushnell StableView binoculars use advanced technology in optics, electronics, and ergonomics. The stabilization feature built into these binoculars cancels out vibration from the outside and the shake that occurs with hand-held use, offering stabilized viewing without a tripod, even at high magnifications. Your Bushnell StableView has an exclusive feature, providing two different stabilization modes in one binocular for the first time. Normal mode is designed to counteract the long, slow motion encountered in a boat, plane or car, and is also ideal for tracking moving subjects such as a bird in flight. Fine mode compensates for short, rapid external vibration, designed to be very effective against the visible effect of hand held shake (tremor) that many experience with high power binoculars. The modes are easily set, and you can quickly switch between them.
