Zoom Binoculars offer the user a variable magnification. The typical magnification of a Binocular is 7x – 10x. However, Zoom Binoculars can be made at much higher magnifications. Keep in mind, however, that as you increase magnification, you decrease available light.
A tripod is often necessary to steady images at very high magnifications. Zoom Binoculars are a great alternative for those seeking higher magnification, without the limitations of a fixed, high-powered Binocular.
