The image stabilized StabilEyes offers hunters rock-steady, high magnification viewing and spotting in a waterproof/fogproof package. Hand-holding a high magnification binocular is difficult, but when it's cold outside, it's windy - or you're just plain excited - getting a sharp, steady image can be nearly impossible. Nikon developed the StabilEyes binoculars to effectively eliminate those blurred high magnification images. To achieve this incredible image stabilization, StabilEyes used a servo control system with the prisms supported by gimbals to provide a view that is unaffected by either shake or vibration. All lenses are fully multicoated, and all prisms are phase-correction coated for the ultimate in brightness and resolution. Uses 2 AA batteries, included. -Focusing System- Center Focus -Magnification- 16X -Objective Diameter- 32mm -Angular field of view - 3.8 -Angular field of view - 60.8 -Field of view at 1000 yards- 198 ft. -Close Focus Distance- 11.5 ft. -Exit Pupil- 2 mm -Relative Brightness- 4 -Eye Relief- 15mm -Length- 7.1 -Width- 5.6 -Weight - 39.5 oz. minimize
