German Precision Optics Passion ED Features The German Precision Optics Passion ED binocular uses ED glass technology in its objective lenses to control chromatic aberration and deliver sharp true to life color across the field of view. A Schmidt Pechan roof prism design keeps the body compact while GPObright high transmission coatings on every glass surface brighten the image and improve contrast. With a 42mm objective and a 4.2mm exit pupil the optic gathers enough light for dawn and dusk glassing sessions when game is most active. A field of view of 340 feet at 1000 yards and 16mm of eye relief give users a wide comfortable view even for those wearing glasses. The magnesium micro bridge body keeps overall weight to about 26 ounces while still standing up to drops and rough handling in the field. Tough aluminum eyecup tubes resist wear from repeated glassing sessions and the center focus system allows quick precise adjustments with one hand. Waterproof and fogproof construction means the Passion ED performs reliably in rain humidity and sudden temperature swings without fogging internally. Backed by GPO s industry leading lifetime warranty and shipped in a custom molded hard case this binocular is built for hunters and outdoor enthusiasts who need dependable glass trip after trip.
