This spotting scope utilizes a combination of extra-low dispersion and pure fluorite crystal glass, coupled with optical lens coatings, to produce views free from chromatic aberrations, high light transmission, and improved color rendition, resolution, contrast, and clarity. Additional design elements include a specially designed ring and bayonet mount that allows the use of a suite of accessories and eyepieces to enhance your user experience and expand the capabilities of your scope.

Optical Performance

Powerful 30-70x wide angle eyepiece allows you to scan the terrain for subjects on low power with the ability to zoom in and make detailed observation and positive identification
Front XD lens is made of extra-low dispersion glass and the secondary is made of fluorite crystal glass creating an optical path free from chromatic aberrations at even high magnification with high contrast and crisp clarity
Massive 99mm objective lens delivers outstanding low light performance with exceptional detail
Anti-reflection fully multicoated lenses maximize light transmission and improve color rendition, resolution, contrast, and clarity
Proprietary KR coating on the exterior of the lens actively repels dirt, moisture, and dust from collecting on its surface to ensure clear views
105-foot field of view on 30x, 60 feet on 70x

Use and Handling

Eyepiece socket is set in-line with the body to make finding subjects faster and tracking moving targets easier
Dual-focus system: Quick (coarse) focus allows for fast action to bring your subject in to detail in just a few smooth revolutions and Fine focus gives pin-point, finger-tip control offering precise focusing accuracy with minute adjustments possible, even when wearing gloves—increasing performance for applications such as digiscoping when accurate focus is critical
Eyepiece quick release button allows the eyepiece to be removed smoothly for quick eyepiece or adapter changes without compromising on a secure connection to the scope body
Tripod mount has a removable screw that allows the spotting scope to be attached to either 1/4"-20 and 3/8"-16 heads and quick release plates
The orientation of the scope can be changed with the release of a locking button for precise eyepiece placement to improve viewing comfort
An easily accessible collar on the eyepiece mount allows for quick connection of current Kowa System accessories, including adapters for digiscoping and a 1.6x extender
105mm objective filter thread allows for a protective or UV filter to be added—the sunshade can still be used even with a filter installed
Lens hood has a built-in aiming sight as a visual aid to assist in finding a subject more rapidly

Construction Details

Compact design measures under 15" long
Lightweight, strong, and corrosion-resistant magnesium alloy chassis
