10 x 42 PASSION HD binoculars are the flagship products of GPO. They are built to the highest optical standards, with incredible low-light optical benefits. Users can see exceptionally fine detail from extreme distances while enjoying excellent color contrast images. This visual quality can only be made possible using GPO’s proprietary GPObright lens coating technology. PASSION HDs have wide-angle field of view, making users feel as if they are part of the spectra they are viewing. They are exceptionally lightweight and compact, making them feel nearly invisible around the user’s neck.
