Product Overview
The PASSION™ 8x42HD binoculars offer low-light, high-performance optics to assist your viewing in the lowest light conditions. Sacrificing a little magnification creates better low-light performance via an exit pupil beam 20 percent larger than its 10x rival. These binoculars deliver high transmission of 99.7 percent of the available light through every lens surface, and a wide exit pupil of 5.25mm allows you to literally see game at night. All PASSION HD binoculars feature high-resolution, high-transmission optics and carry the industry’s best Spectacular Lifetime Warranty.™

Key Features:
GPObright is a proprietary coating process that maximizes light transmission through each surface of an optical element. As light hits an optical surface, normal uncoated high-performance glass can reflect up to 5% of that light, redirecting this light so it does not transmit through the optical system. However, when these high-performance lenses are vacuum-coated with GPObright lens coatings, up to 99.7% of the available light passes through each optical surface. Furthermore, when every surface of the entire optical system is properly coated, total light transmission can reach up to more than 92%, making the optical image of a GPO binocular or riflescope “bright,” even in the lowest light conditions.
A Double HD lens is the final product, created when multiple extra-low dispersion lenses are chemically laminated to make a single, multilayer high-performance optical lens. Laminating multiple lenses minimizes light reflection on the surface of multiple lenses, creates enhanced resolution and color contrast images, and minimizes chromatic aberrations. This benefit is clearly visible with all GPO products supporting this feature. This high-performance process is routinely found in the photographic market and with the highest quality photographic lens manufacturers, but has now transitioned into premium sporting optics.
