Built with a magnification and objective lens diameter favored by experienced birders, hunters, and outdoor enthusiasts, GPO 10x42 Passion ED Binocular combines phase-corrected BAK4 Schmidt-Pechan prisms, extra low-dispersion glass, and anti-reflective fully multi-coated optics that work together to produce clear and bright images with accurate color representation across the entire wide field of view without distortion, or spherical or chromatic aberrations. When combined with its generous eye relief and comfortable exit pupil, users will be presented with a panoramic and immersive observational experience in the field, at the range, or in the blind; and when out on the water the common disorientation experienced when glassing in rolling seas is greatly minimized.

Its sturdy magnesium alloy chassis helps to keep the weight down without sacrificing strength, while its micro-bridge design frees up more space on the optical tubes for the user's hands to improve grip strength and stability. The binocular is wrapped in a protective rubber armor that provides a non-slip grip even in cold and wet weather. Each optical tube is nitrogen-filled and O-ring sealed to be waterproof, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions.

From dawn to dusk and in all weather conditions, the Passion ED binocular will become an invaluable addition to your kit for all types of outdoor activities.

Optical Performance

• High 10x magnification enables detailed observation of distant subjects
• 42mm objective lenses boost light-gathering ability versus compact models for improved low-light performance without the bulk of larger objectives
• Compact BAK4 Schmidt-Pechan prisms allow for thinner optical tubes versus the more common Abbe-Koenig prism
• Phase-correcting prism coatings reduce internal light interference to help improve contrast and overall image sharpness
• Extra low-dispersion (ED) glass corrects for spherical and chromatic aberrations, astigmatism, and off-axis comas to produce crisp and sharp images with accurate colors especially at the edges
• Proprietary GPObright fully multi-coated optics limit light loss while further improving image brightness, color rendition, and contrast
• Wide 65° apparent angle of view produces an immersive observational experience
• 426-foot field of view at 1000 yards

Use and Handling

• Compact yet strong magnesium micro-bridge exposes more surface area on the optical tube to improve hold and comfort without sacrificing strength
• Large textured slip-resistant center focus wheel is easy to manipulate even while wearing gloves
• Sturdy machined aluminum right-eye diopter ring, ±3 dioptric correction range for precise focus adjustment to most user's individual eye prescription
• Twist-up click-stop eyecups for comfortable use with or without eyewear
• 56-73mm interpupillary adjustment range
• Tripod mountable with optional adapter for hands-free use, and reduced arm fatigue and vibrations
• 16mm eye relief makes long-duration glassing sessions more comfortable
• 4.2mm exit pupil will cover most pupils as they open and dilate in low-light conditions
