OPTISAN 37569 EVE 2.5-10X50I

Step into the field with confidence and clarity thanks to the OPTISAN EVE 2.5-10X50I hunting scope, engineered in collaboration with Europe’s champion marksmen. Every one of its 90–150 precision components undergoes more than 200 in-house quality checks to ensure reliable performance under harsh conditions while maintaining competition-grade accuracy.

Designed as a versatile powerhouse, the EVE 2.5-10X50I delivers an ideal balance between wide-angle viewing and precise target acquisition. At 2.5X magnification, it offers a wide 42-foot field of view at 100 yards, making it perfect for scanning open terrain and tracking fast-moving game. At 10X, it provides sharp, detailed imaging for accurate shot placement at extended distances.

Its fully multi-coated optics ensure bright, high-contrast images even in low-light conditions such as dawn or dusk. The German No.4 reticle features a clean, minimal design that allows for quick target acquisition, while the fine red center dot enhances precision without obstructing the sight picture.

Built for durability, the scope uses a one-piece aircraft-grade aluminum tube with a matte black finish for reduced glare and enhanced strength. It is JIS7 waterproof, nitrogen-purged for fog resistance, and designed to operate reliably in temperatures from –20°C to +50°C. Low-profile, tool-less resettable turrets with 0.1 mrad clicks allow fast adjustments and easy return-to-zero functionality.

User comfort is prioritized with 3.8″ to 3.5″ eye relief and a +2/–2 diopter adjustment for a sharp, customized view. A fixed parallax setting at 100 yards ensures consistent aiming, while six illumination levels provide control in varying light conditions. Weighing just 664 g, it delivers rugged performance without unnecessary bulk.

Whether stalking game or engaging distant targets, the OPTISAN EVE 2.5-10X50I delivers precision, clarity, and reliability when it matters most.
