The 20x50 HD Porro Binoculars from GVM are useful for a wide range of outdoor activities, from hiking the trail, to spotting down range, or for counting points at long ranges. Anti-reflection multicoated optics and BAK4 prism glass transmit bright, clear images throughout their entire focus range with improved color rendition and contrast. Utilizing the traditional Porro prism design not only delivers a rich depth of field to more easily discern near objects from those farther away, but also creates a naturally balanced optic that sit comfortably in the hand for steadier views.
