Switching between scanning at low magnification and confirming detail at 60x with a single focus knob means constant back-and-forth. The Athlon Cronus G2 UHD Dual Focus 20-60x86 pairs the flagship Cronus optics with a dual-speed focus system — coarse for fast target acquisition, fine for critical focus at high magnification — the same kind of precision focusing found on premium telescopes, applied to a field spotting scope.

At 20x the field of view spans 117 feet at 1,000 yards — wider than the standard model's 111 feet — making it efficient for scanning open country. The apochromatic lens system controls chromatic aberration better than standard ED designs, and the ESP dielectric coating reflects over 99% of light through the BAK-4 prism assembly, delivering the brightness and color fidelity that separate the Cronus G2 from everything else in its price class.

Key Features

• Dual focus system (coarse + fine) — the coarse knob covers the full focus range quickly; the fine knob provides precise, vibration-free adjustment at high magnification. This eliminates the image shake that barrel-focus spotters can produce when you touch the focus ring on a tripod-mounted scope
• Apochromatic UHD glass with advanced fully multi-coated lenses — triple-element apochromatic correction brings all three wavelengths into focus simultaneously, virtually eliminating the purple fringing that plagues standard ED spotting scopes. XPL protective coating sheds water, oil, and dirt
• ESP dielectric coating on BAK-4 glass prisms reflects over 99% of light through the prism assembly, delivering the brightness and contrast needed to resolve fine detail — antler tines at 800 yards, plumage detail on distant shorebirds, or bullet trace across a valley
• 86mm objective lens — the largest in Athlon's spotting scope lineup, gathering more light than 80mm and 85mm designs for brighter images and more usable time at dawn and dusk
• Magnesium alloy chassis at 73.5 ounces with rotating tripod collar and 45° angled eyepiece. Argon purged and fully waterproof for year-round field use
• 15.2-inch body length — an inch shorter than the standard barrel-focus model, with the same weight and optical performance

Ideal For

Hunters who glass at high magnification and want precise focus control without fighting barrel vibration. When you're trying to confirm antler points at 60x across a canyon at first light, the fine focus knob lets you hit peak sharpness without shaking the image off target.

Target shooters and PRS spotters who need to read mirage, spot trace, and call impacts at 40x or higher. The dual focus keeps the image stable while you fine-tune, and the 117-foot field of view at 20x makes finding targets between stages fast.

Birders and wildlife observers committed to high-magnification work — digiscoping, shorebird identification at distance, or hawk migration monitoring. The fine focus is especially valuable when digiscoping, where even small focus adjustments at high power dramatically affect image quality.

Prefer simpler mechanics? The standard Cronus G2 UHD 20-60x86 delivers the same optical platform with a single barrel-focus ring — lighter on controls, identical glass. For a compact tactical option with an FFP mil reticle, the Cronus G2 UHD 7-42x60 packs Cronus-grade optics into a 46.6-ounce straight body.
