Athlon Optics Argos G2 HD 10x50 Binoculars

Standard 42mm binoculars lose contrast fast at dawn and dusk — exactly when wildlife is most active. The Athlon Argos G2 HD 10x50 brings ESP dielectric-coated, phase-corrected BAK-4 roof prisms and a 5.0mm exit pupil to the sub-$250 price class, where most competitors still use standard multi-coatings. The larger 50mm objectives gather 42% more light than 42mm models, extending your usable observation window into the low-light hours that matter.

Key Features

• ESP dielectric coating on phase-corrected BAK-4 roof prisms reflects over 99% of light through the prism assembly — a feature rarely found below $300. The result is brighter, more color-accurate images than the silver-coated prisms used by most competitors at this price
• HD glass with advanced fully multi-coated lenses and XPL protective exterior coating delivers sharp images with reduced chromatic aberration while protecting the glass from scratches, dirt, and oil in field conditions
• 10x magnification with a 50mm objective balances reach with light-gathering. The 5.0mm exit pupil is the largest in the Argos G2 HD 50mm range, sustaining a bright, usable image deeper into dawn and dusk than the 12x model's 4.2mm exit pupil
• Magnesium alloy chassis at 31.5 ounces — argon purged and fully waterproof, with an ergonomic grip designed for stable one-handed use
• 17mm eye relief with twist-up eyecups — generous enough for comfortable use with glasses, and a wide 56-76mm IPD range that fits more face shapes than most binoculars in this class

Ideal For

Budget-conscious hunters who want the best available glass for dawn and dusk — when the 5.0mm exit pupil and ESP dielectric coating deliver a visibly brighter image than competitors with silver-coated prisms. The 10x magnification is enough for evaluating game at typical engagement distances while keeping the image stable.

General-purpose outdoor users — wildlife watching, hiking, sporting events — who want a capable, weatherproof 10x50 without overspending. The Argos G2 HD delivers ESP dielectric performance at a price point where most alternatives cut corners on prism coatings.

Stepping up from the 12x50? The Argos G2 HD 12x50 has more reach but a narrower field and smaller exit pupil. Stepping up in glass? The Midas G2 UHD 10x50 upgrades to UHD extra-low-dispersion glass with wider FOV and lighter weight.
