Athlon Optics Argos G2 HD 10x50 Binoculars

Dawn and dusk are when wildlife is most active, and when a 50 mm objective's extra light helps most. 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. 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, for what Athlon calls "a clear, bright image that displays accurate color reproduction."
• 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 for adjusting to your eye spacing

Ideal For

Budget-conscious hunters who glass at dawn and dusk, when the 5.0mm exit pupil and ESP dielectric coating matter most. 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 brings ESP dielectric prism coatings to a 10x50 at this price.

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.
