Overview

With a powerful magnification and a relatively compact design, the Master-HD gives users the ability to discern details at distance without weighing them down.

This binocular features silver-alloy-coated roof prisms and anti-reflection multi-coated optics that produce bright and clear high-contrast images with true color rendition across the spacious and wide field of view. The 42mm objectives boost its light-gathering ability to improve views in challenging light such as at dawn and dusk or in foggy and cloudy weather without the bulk and weight of larger-objective models. The combination of prisms, optical coatings, wide field of view, and comfortable eye relief allow users to enjoy a comfortable and immersive observational experience in most lighting conditions.

Complementing the optical performance are construction details that make this binocular durable and comfortable to use. It has a lightweight and corrosion-resistant reinforced polycarbonate resin chassis and is protected by black rubberized armor that is textured for a secure non-slip grip. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof and submersible, as well as resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A tethered one-piece ocular rainguard covers the eyecups as the binocular hangs around the neck and prevents rain and spraying water from filling them.

Whether you're hunting or birding, boating or watching your favorite team, this Master-HD will quickly become indispensable for all your outdoor activities.


Optical Performance

  • High 10x magnification brings distant objects in close for detailed observations
  • 42mm objective lenses improve light-gathering ability without adding excessive bulk or weight
  • Roof prism light path ensures optical tubes remain thin for a compact form factor
  • Anti-reflection multi-coated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity
  • High-reflectivity silver-alloy prism coatings reduce internal diffraction to further improve light transmission and contrast
  • Wide 61° apparent angle of view helps to minimize the appearance of visible handshake that is common when holding high-power optics such as this
  • 325' 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
  • Twist-up/click-stop rubber eyecups for use with or without eyewear
  • 15.2mm eye relief helps to reduce eye strain and improves viewing comfort
  • Comfortable 4.2mm exit pupil will cover most pupils as they open and dilate in low light to keep the full scene in view

Construction Details

  • Nitrogen-filled and O-ring sealed to be waterproof and submersible to a depth of 3.3' (1m) for up to 30 minutes and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
  • One-piece tethered ocular rainguard protects eyecups from water pooling in them from rain or spraying water when hanging from the neck
  • Textured protective rubber armoring provides a slip-resistant grip, especially in cold and wet weather
  • Weight: 26.1 ounces
