Nikon 20x56 Monarch 5 Binocular (Black)

Optimized for long-range use, Nikon's 20x56 Monarch 5 Binocular is the most powerful 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 extra-low dispersion glass elements with anti-reflection, fully multi-coated 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 its 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 this binocular durable and comfortable to use. It has a lightweight, reinforced polycarbonate ATB chassis and is protected by rubberized armor that is accented with indented palm rests to give it a secure non-slip 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 binocular hangs around the neck and prevents 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 it is held by hand, so Nikon includes an adapter that allows the Monarch to be easily mounted on a tripod or other support system for hands-free use.

Optical Performance
Powerful 20x power is optimized to make detailed observation and identification at extreme distances
Large oversized 56mm objectives maximize light-gathering ability and help to offset the dimming of the view that often accompanies high-power optics when viewing at long range
Roof prism light path ensures optical tubes remain thin for a compact form factor
Extra low-dispersion glass reduces chromatic and spherical aberrations for increased contrast, improved color rendition, and sharpness without distortion across the entire field of view
Phase-corrected prism coatings reduce internal interference to improve light transmission, contrast, and resolution
Anti-reflection fully multi-coated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity
Highly reflective dielectric prism multi-layer coatings boost internal reflection to >99% to maintain image brightness and improve contrast and clarity
173' field of view at 1000 yards
Use and Handling
Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism
Large slip center focus wheel allows for precise focus control, even while wearing gloves
Right eye dioptric adjustment collar helps to compensate for individual eye prescription
60-72mm interpupillary distance range allows easy use by a wide variety of people
Twist-up/click-stop rubber eyecups for use with or without eyewear
Tripod mountable with optional adapter for hands-free use to eliminate arm fatigue and hand shake
Long 16.4mm eye relief helps to reduce eyestrain and improves viewing comfort
2.8mm exit pupil
Construction Details
Environmentally friendly Eco-Glass is made without lead and arsenic
Lightweight and durable fiberglass-reinforced polycarbonate chassis
Chassis material is temperature resistant, preventing the expansion and contraction that is common with metal, which can cause the optical components to move out of alignment over time and prevent sharp focus
Textured protective rubber armoring provides a slip-resistant grip, especially in cold and wet weather
Indents on the sides of the optical tubes are ergonomically placed where the hands naturally fall for a more comfortable feel in the hand and a more secure grip
Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
Tripod adapter included for easy mounting onto an array of support systems
Black coloring allows it to remain inconspicuous in all environments
One-piece tethered ocular rainguard protects eyecups from water pooling in them from rain or spraying water when hanging from the neck
Tethered fold-down objective lens caps prevents losing them during observation sessions
