These Docter Optic ED 40x80 super wide angle binoculars offer high magnification viewing without compromising the field of view, making them perfect for game spotting, astronomy, and more! The binoculars feature an open hinge to connect the two halves of the body and one-hand "through grip"! The extra low dispersion glass reduces color distortion while the Noblex (formally Docter) multitop broadband coating provides high contrast images. The binoculars include a rugged backpack for safe and comfortable transport to and from viewing locations.
