German Precision Optics Passion SD Features The German Precision Optics Passion SD 10x34 Binoculars are built around high grade SD or substantial definition glass that delivers enhanced resolution and color fidelity compared to standard glass elements. Fully multicoated optics paired with GPO s proprietary GPObright lens coating technology push more usable light through the system which translates directly into a brighter higher contrast view at dawn and dusk. The Schmidt-Pechan roof prism system uses BAK-4 glass with a dielectric coating to preserve image brightness and color accuracy across the full 10x magnification range. A 314 foot field of view at 1000 yards gives users a wide window for tracking moving game or scanning open terrain quickly. Built on a magnesium frame the Passion SD 10x34 wraps that lightweight structure in full rubber armor for a secure grip and added protection against drops and knocks in the field. Rotating eyecups adjust to deliver the correct 16mm eye relief for both eyeglass wearers and shooters who prefer direct eye contact with the lens. The housing is fully waterproof and fogproof so the binoculars perform reliably through rain humidity and rapid temperature changes without fogging internally. Weighing only 17.2 ounces this compact 10x34 binocular is easy to carry all day making it a dependable companion for hunters birdwatchers and outdoor enthusiasts alike.
