Athlon Optics Argos G2 HD 8x42 Binoculars

The Athlon Argos G2 HD 8x42 delivers ESP dielectric-coated, phase-corrected BAK-4 prisms, a 371-foot field of view, and an open-bridge design for under $220 — making it the most affordable way into dielectric-coated 8x42 performance in Athlon's lineup. The 8x magnification is inherently more stable than 10x for hand-held use, the wider field catches movement that higher magnifications miss, and the 5.3mm exit pupil keeps the image bright in forest canopy and low light.

Key Features

• ESP dielectric coating on phase-corrected BAK-4 roof prisms reflects over 99% of light through the prism assembly — the same coating technology used on binoculars costing $400+. At this price, most competitors use silver-coated prisms that lose significantly more light
• HD glass with advanced fully multi-coated lenses and XPL protective exterior coating delivers clean, bright images while protecting the optics from scratches, dirt, and oil in field conditions
• 8x magnification with a 42mm objective produces a 5.3mm exit pupil and 371-foot field of view at 1,000 yards — the widest in the Argos G2 HD lineup. The wide field and lower magnification make it easier to find, track, and stay on moving subjects
• Open-bridge magnesium chassis at 25.5 ounces — the open bridge provides a secure one-handed grip for comfortable carrying on long walks. Argon purged and fully waterproof
• 17.3mm eye relief with twist-up eyecups — the most generous in the Argos G2 HD line, with a wide 56-76mm IPD range that accommodates glasses wearers and a broad range of face shapes

Ideal For

Beginning birders and casual wildlife watchers — the Argos G2 HD 8x42 is where ESP dielectric performance meets a price that doesn't require justification. The wide field, stable 8x magnification, and bright image make birding approachable, and the open-bridge grip is comfortable for long walks.

Hikers and travelers who want a capable, weatherproof binocular they can toss in a pack without worrying. Magnesium chassis, waterproof, argon purged — built for real conditions at a budget price.

Want sharper glass? The Argos G2 UHD 8x42 upgrades to extra-low-dispersion glass on the same open-bridge chassis for $50 more — reducing chromatic aberration for cleaner edges and truer color.
