Overall

With a compact form factor like a binocular but offering the zoom performance of a larger spotting scope, the Cyclops monocular is the wise choice for outdoor enthusiasts, curious urban explorers, birders, shooters, and hunters who need to move fast and glass on the go. It sports a wide zoom range that allows you to scan the terrain for subjects with a wide field of view, then dial up the magnification to make detailed observations and identification. Its large 50mm objective, anti-reflection fully multi-coated optics, and BAK4 roof prism maximize light throughput to keep views crisp and bright even in low light or when viewing targets at extremely long range on maximum magnification.

The rubber-covered polycarbonate chassis maintains a consistent neutral temperature even in cold weather, so it is comfortable to hold all year round. Textured knurling on the focus knob and zoom ring enable precise control for fine adjustments to get the perfect view. You can attach the monocular to most tripods and heads if you're planning on staying stationary for a time and want to enjoy hands-free and vibration-free viewing at the beach, in a blind, on a balcony, or downrange.

Optical Performance

  • 3:1 zoom mechanism provides a wide range of magnifications that fit just about any glassing task from hunting and shooting to birding and general observation
  • Low 10x magnification brings distant subjects in for observation while preserving a wide exit pupil, long eye relief, and generous field of view
  • High 30x power allows for detailed identification of distant subjects
  • Large 50mm objective lens draws in copious amounts of light to ensure bright and clear views even in low or challenging light, or when observing targets at extreme long range on maximum magnification
  • Roof prism light path ensures a slim form factor for easier handling
  • BAK4 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
  • Anti-reflection fully multi-coated optics maximize light transmission to ensure bright and clear high-resolution images with accurate colors and improved contrast and clarity
  • Less than 10-foot minimum focus distance enables detailed observation of small subjects like hummingbirds, insects, flora, fauna, and flowers at close range
  • 126ft field of view at 1000 yards on 10x, 99ft on 30x

Use and Handling

  • Large textured focusing wheel and magnification collar enable precise adjustments in cold weather and while wearing gloves
  • Standard 1/4"-20 tripod mount is compatible with most photo/video/field tripods and heads, quick release plates, and other support systems like monopods and window mounts
  • Twist-up rubber eyecup for comfortable viewing with eyeglasses or sunglasses
  • Exceptional 16mm eye relief at 10x maximizes viewing comfort with reduced eyestrain; comfortable 16.5mm on 24x
  • Wide 5mm exit pupil on 10x is optimized for low-light use for maximum coverage of dilated pupils; 1.7mm on 30x

Construction Details

  • Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
  • Lightweight and temperature-resistant polycarbonate chassis
  • Anti-vibration rubber coating protects the housing while providing a slip-resistant grip
  • Weight: 15.97 ounces
