Designed for the outstanding optical performance required for experienced birders, hunters, and outdoor enthusiasts, GPO black 8x42 Passion HD Binoculars use individual extra low-dispersion (ED) glass lenses that are laminated together into a single unit to minimize internal light reflection and chromatic aberration — which enhances resolution, contrast, and color rendition beyond what ED glass does in a traditional lens design.

Added to this Double HD lens configuration, the Passion HD combines phase-corrected BAK4 Schmidt-Pechan prisms, and anti-reflective fully multi-coated optics that work together to further enhance the optical properties and 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 ultra-long 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.

All exterior lens surfaces are treated with GPO's proprietary PASSIONdrop hydrophobic coatings, which repel water, dust, oil, and dirt to make them smudge repellent, help them stay cleaner longer, and easier to clean. 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 binoculars are 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 HD binoculars will become an invaluable addition to your kit for all types of outdoor activities.

Optical Performance

• Moderate 8x magnification helps to maintain a wide field of view
• 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
• Double HD lens configuration: Multiple lenses are chemically laminated to make a single, multilayer high-performance optical lens that minimizes light reflection, creates enhanced resolution and color contrast images, and minimizes chromatic aberrations
• Proprietary GPObright fully multi-coated optics limit light loss while further improving image brightness, color rendition, and contrast
• 57° apparent angle of view produces an immersive observational experience
• 375-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, broad ±4 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
• 57-75mm interpupillary adjustment range
• Tripod mountable with optional adapter for hands-free use, and reduced arm fatigue and vibrations
• Extra-long 19.5mm eye relief makes long-duration glassing sessions more comfortable without eye strain
• Wide 5.25mm exit pupil will cover most pupils when they open and dilate in low-light conditions for clearer views
