Optimized for long-range use, Nikon's 20x56 Monarch 5 Binoculars are the most powerful binoculars in the Monarch series and received upgrades from the Monarch 3 design to improve image quality with the same focus on comfort and performance the line is known for.

Featuring extralow dispersion glass elements with anti-reflection, fully multicoated optics and highly reflective dielectric-coated and phase-corrected roof prisms, the Monarch 5 produces bright and clear high-contrast images with accurate color rendition and minimal color fringing across the entire field of view. The oversized objectives boost their light-gathering ability and help to offset the dimming of the view that often accompanies powerful optics such as this when observing long-distance subjects—ensuring bright and clear views even in challenging light conditions.

Complementing the optical performance are construction details that make these binoculars durable and comfortable to use. They have a lightweight, reinforced polycarbonate ATB chassis and are protected by rubberized armor that is accented with indented palm rests to give them a secure nonslip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A one-piece ocular rainguard covers the eyecups as the binoculars hang around the neck and prevent rain and spraying water from filling them, and the objective lens caps are also tethered to keep them safe from being lost on the forest floor. The combination of high power and large objectives may cause distracting hand shake or arm fatigue when they are held by hand, so Nikon includes an adapter that allows the Monarch binoculars to be easily mounted on a tripod or other support system for hands-free use.
