The most powerful binoculars available. Widely used on commercial, fishing, and military vessels as well as for astronomical observation, these large-size binoculars with 80 mm large-aperture objective lenses are binoculars of the highest quality. By applying a multilayer anti-reflection coating (Electron Beam Coating) to each lens element, these binoculars produce a sharper image. Boasting precise resolving power and superior light condensing power, they are ideal for exacting observations in specialized fields.
