The new Monarch ATB™ features an advanced new roof prism optical design. It incorporates Nikon’s exclusive Eco-Glass (made without the use of arsenic or lead) for all lens and prism elements. Prisms feature phase-correction coatings and high reflection mirror coatings for superior sharpness and resolution, and all lenses and are fully coated with multiple layers of anti-reflective compounds for maximum light transmission. The result is much improved low-light brightness, edge-to-edge sharpness, and definition.

Built with an extremely durable alloy body housing, the Monarch ATB™ is ruggedly constructed for true waterproof, fogproof and shockproof performance.

Ergonomic styling, mated with a new rubber armored exterior provides added shock resistance and a firm grip, wet or dry. Turn and slide rubber eyecups, complemented by long eye relief, allow the binoculars to be used as comfortably by eyeglass wearers as those with uncorrected vision. A large central focus wheel and adjustable diopter make focus easy to achieve and maintain, even while wearing gloves.
