Apresys Optics S4210 overview

  • 1Description

Designed for performance from dawn to dusk, the Apresys Optics 10x42 S4210 Binocular is engineered with high-density phase-corrected BAK4 roof prisms and broadband anti-reflection fully multi-coated optics to produce bright and clear high-contrast images with accurate color fidelity and limited distortion. Its wide viewing angle helps to minimize the appearance of visible hand-shake that is common with high-magnification optics, and the larger objectives draw in copious amounts of light versus smaller objectives to boost low-light performance without sacrificing image brightness, color, or resolution.

Ergonomically designed with thumb-rest indentations and raised palm ridges to improve grip strength and comfort for long glassing sessions, the chassis is made of a lightweight and impact-resistant composite chassis that is wrapped in a protective slip-resistant rubber armor. The optical tubes are nitrogen-filled and O-ring sealed to make them waterproof and resistant to fogging when moving through extreme temperature changes. A large center focusing wheel, ±3 dioptric correction, and twist-up eyecups enable precise focusing and eye relief for just about any user.
