Optisan 04017 LR 10×34

Introducing the OPTISAN 04017 LR 10X34—a precision-engineered monocular born from battlefield-tested performance and competition-proven optics. Crafted in collaboration with Europe’s top shooters, every unit undergoes more than 200 rigorous quality checks across 90–150 individual components, ensuring unwavering reliability when you need it most. From the first glance to the final detail, you’re experiencing the same meticulous standards that earned champion shooters’ trust.

At just 453 g (15.98 oz) and complemented by a neoprene shoulder strap, this monocular feels almost weightless in your hand—perfect for full-day birdwatching, insect studies or nature hikes with the whole family. Its LR series open-hinge design offers a natural, one-handed grip so you can steady your view while fine-tuning focus with your free hand. The result? Crisp, true-color images with zero distortion, even at the edges.

Optisan’s advanced Japanese optical system and fully multi-coated lenses deliver 80 % light transmission for breathtaking brightness in low-light conditions. A Bak4 prism with phase-corrected, silver coating boosts contrast and resolution, revealing fine feather patterns and the subtlest wing movements. With a generous exit pupil of 3.4 mm and 16 mm of eye relief, you enjoy fatigue-free viewing and comfortable long sessions, glasses or no glasses.

Built to endure the elements, the OPTISAN LR is IPX7-rated waterproof and fog-proof, nitrogen-purged and sealed against submersion up to 1 m for 30 minutes. Roam worry-free through rain, fog or dusty trails—your view remains crystal clear. A twist-up eyecup adapts instantly to your preferred eye position, while removable lens caps and an anti-tangle strap design keep your gear organized and ready.

Whether you’re tracking warblers at dawn or scouting targets in competition, the OPTISAN 04017 LR 10X34 pairs championship pedigree with field-ready convenience—transforming every outdoor moment into an immersive visual adventure.
