The GPO PASSION™ APO 20-60x85 (model SP300) is an apochromatic angled spotting scope designed for high-magnification, color-corrected optical observation across extended distances. Built with an 85 mm objective lens and proprietary GPObright™ multi-coatings, the optical system delivers up to 92% light transmission while suppressing chromatic aberration and color fringing. A 45° angled eyepiece configuration paired with a lockable 360° rotating tripod mounting collar provides ergonomic viewing from shooting benches, hides, or vehicle mounts. The internal assembly features a magnesium chassis, a brass gear helical central focus ring, an integrated pull-out sunshade, and a nitrogen-purged fogproof body encased in rubber armouring.

Key Features

• Apochromatic Optical System: APO objective lens design paired with GPObright™ multi-coatings minimizes color fringing and maximizes edge-to-edge clarity.
• Continuous 20–60x Zoom: Provides wide-area scanning at 20x magnification (36 m field of view at 1,000 m) and fine-detail resolution up to 60x (20 m field of view at 1,000 m).
• Brass Helical Focusing: Internal brass gearing delivers smooth, precise focus adjustments across the entire focal range.
• Rotating Tripod Collar: Rotates 360 degrees around the optical axis with a standard 1/4"-20 interface for flexible positioning on tripods and window mounts.
• Rugged Magnesium Chassis: Durable, nitrogen-purged waterproof and fogproof magnesium construction protected by rubber armouring.

Who is the GPO Passion APO 20-60x85 for?

• Long-range big game hunters — requires the 85 mm objective lens and continuous 20-60x zoom magnification to resolve antler points, anatomical detail, and game movement across distant valleys in low-light conditions.
• Precision rifle shooters — relies on the 60x maximum magnification of this apochromatic spotting scope to read mirage, spot bullet impacts, and verify target scoring on long-range firing lines.
• Stationary ornithologists and wildlife observers — utilizes the 1,786 g magnesium body with a 45° angled eyepiece to conduct extended, fatigue-free stationary observation of birds and distant wildlife beyond its 6.0 metres minimum focus distance.

Less suitable for: Mobile, ultralight backcountry hunters where carrying a 1,786 g optic is impractical; a compact 50–65 mm spotting scope or high-magnification handheld binocular is better suited for weight-restricted pack hunting. It is also unsuitable for close-range observation under its 6.0 metres minimum focus limit, where a dedicated close-focus binocular is required.
