Optical Performance
- Broad 15-45x fixed zoom eyepiece is ideal for mid- to long-range use
- 65mm objective lens gathers the light required to use in challenging conditions and to ensure bright views when looking at distant subjects at high power
- Traditional Porro prism light path produces clear and bright views without internal light interference
- Dielectric prism coatings boost surface reflectivity to greater than 99% for maximum light transmission through the prism, with minimal loss and diffraction
- High-density (HD), extra-low dispersion (ED) glass lens elements reduce chromatic and spherical aberrations for increased contrast and improved color rendition and sharpness without distortion across the entire field of view
- Proprietary XR anti-reflection fully multi-coated optics increase light transmission for accurate color fidelity and improved contrast and clarity
- ArmorTek exterior lens coatings resist scratches and abrasions while allowing oil, dirt, and sap to be cleaned off without leaving smudges or residue
- 136.5-foot field of view at 1000 yards at 15x; 68-foot field of view at 45x
Use and Handling
- Straight-though viewing eyepiece makes finding subjects fast and tracking moving targets easy
- Helical focusing mechanism focuses smoothly and quickly without rotating lens elements to maintain optical alignment for tack-sharp views
- Large slip-resistant focusing collar is easy to manipulate in cold and wet weather or while wearing gloves
- Twist-up rubber eyecup for comfortable use with or without eyewear
- Standard 1/4″-20 mount is compatible with a wide variety of quick release (QR) plates, heads, and photo/video/field tripods; mounting shoe is compatible with select QR plates for faster mounting and removal
- Rotating tripod collar allows user to precisely adjust the eyepiece position relative to tripod head
- Long 19.6-17.8mm eye relief improves viewing comfort with reduced eyestrain
- Comfortable 4.3mm exit pupil at 15x will cover most pupils as they open and dilate in low light to keep the whole scene in view without vignetting
Construction Details
- Lightweight and durable magnesium-alloy chassis reduces overall weight without sacrificing strength
- Protective rubber armoring provides a slip-resistant grip for more secure handling during setup and breakdown
- Argon filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions
- Retractable sunshade prevents lens flare that can spook game, reduces glare to maintain contrast and clarity in the view, and keeps rain or snow off of the lens for clearer views in inclement weather
- Nylon stay-on/view-through carrying case protects the spotting scope during transport and storage and allows for faster and safer setup and breakdown
