Hawke Sport Optics Endurance overview

  • 1Description

Designed to provide a powerful optic with a compact form factor, the straight-through viewing Hawke Optics Endurance ED 12-36x50 Spotting Scope is built with extra-low dispersion (ED) glass, a dielectric-coated BAK4 Porro prism, and fully multi-coated optics—and measures just 10.5" long.

The glass, prism, and coatings ensure accurate color rendition with improved clarity and contrast, while the 50mm objective lens draws in copious amounts of light to boost its performance in challenging conditions such as at dawn and dusk or when trying to see into wooded areas under dense canopies. Its broad zoom range allows you to enjoy wide-field viewing at the low 12x with the ability to quickly dial up the power to 36x and make detailed observations of distant subjects with ease.

The chassis is made of polycarbonate, which is corrosion, impact, and temperature resistant, and the optical tubes are nitrogen filled and O-ring sealed to be water and fogproof even in extreme weather conditions. This iteration of the Endurance ED has a two-speed focusing system to allow for fast coarse and precision fine focusing—making it a perfect complement to the wide zoom range. The straight-through viewing configuration makes finding and tracking subjects faster and easier versus angled designs. A 1/4"-20 mount makes it compatible with many tripods, quick-release plates, and other popular support systems like window mounts, while a stay-on/view-through case offers maximum protection.

Optical Performance
  • Broad 12-36x zoom eyepiece allows you to make wide-field observations at low power with the ability to zoom in for detailed views
  • 50mm objective lens helps to preserve the compact form factor for easier handling and carrying
  • Porro prism light path helps to deliver a rich depth of field for a more lifelike viewing experience
  • BAK4 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
  • Dielectric interior prism coatings limit light loss and diffraction to improve contrast, clarity, and resolution
  • Extra-low dispersion glass virtually eliminates chromatic aberrations to reduce color fringing and halos
  • Anti-reflection fully multi-coated optics maximize light transmission to produce bright and clear high-contrast images with accurate color and improved resolution
  • 174' field of view at 1000 yards at 12x power, 90' at 36x magnification
Use and Handling
  • The eyepiece is set in-line with the scope body to make finding subjects fast and tracking moving objects easy
  • Dual focusing mechanism allows for fast coarse and precision fine focusing to make finding and viewing multiple or moving subjects fast and easy
  • Slip-resistant focusing knob is easy to manipulate in cold or wet weather or while wearing gloves
  • Twist-up eyecup allows you to fine-tune your perfect eye relief with or without eyewear
  • Standard 1/4"-20 mount is compatible with most quick-release plates, heads, and photo/video/field tripods and other support systems
  • Comfortable 15mm eye relief reduces eyestrain for easier viewing, especially during long glassing sessions
  • 4.2mm exit pupil at 12x will completely cover most pupils as they open and dilate in low light to keep the scene in view
Construction Details
  • At just 10.5" long, the scope is extremely easy to handle and convenient to use
  • Lightweight, temperature-resistant, and durable polycarbonate chassis
  • Chassis' temperature resistance ensures it stays a comfortable handling temperature in cold or wet conditions, while resisting the expansion and contraction common with metal chassis that can cause the optical components to move out of alignment over time
  • Nitrogen filled for water and fogproof performance
  • Built-in retractable sunshade helps to limit peripheral reflections and lens flare to improve contrast and prevent spooking animals and birds
  • Included stay-on/view-through soft cover offers maximum protection for the spotter while retaining full access to the tripod mount, focuser, sunshade, and eyepiece
