Image stabilization binoculars cut down on shakiness in the viewer. One of the most common problems with binoculars is that the images tend to get shaky, especially with higher magnifications. The longer you use them, the shakier the images get, too, particularly if you have hand tremors. You will likely have to use additional support like a tripod to obtain stable images.
ISBs have an image stabilization mechanism that eliminates the need for additional support. Powered by batteries, they come with sensors that detect movement, which the IS system then corrects.
The good thing about ISBs is that they are versatile and can perform in any terrain for any application. They are suitable for all kinds of activities, such as bird watching, boating, hunting, wildlife observation, and even stargazing.
