Inspired by hunters, and outfitted with a magnification and objective lens combination favored around the world for its versatility, Blaser 8x42 Primus Binoculars combine a slim ergonomic form factor with thoughtfully engineered optical features to give users an optic that is ideal for most outdoor activities.

The optical performance starts with large 42mm objectives to help boost performance as the light fades, with extra-low-dispersion (ED) glass elements and phase-corrected BAK4 Abbe-Koenig roof prisms that help to correct spherical and chromatic aberrations—producing bright and clear high-contrast images with accurate color representation, but without distortion, across the entire wide field of view in all light conditions. Complementing this are the Contrast and Color Corrective Coating (CCC) and Smart Lens Protection (SLP) coatings, which further improve light transmission, color rendition, contrast, and clarity; and help to keep the lenses clear of water and debris to improve views and make cleaning them easier. These optical components work together with the long eye relief and wide exit pupil to present an immersive observational experience from dawn to dusk.

A short-bridge design pulls the center of gravity back toward the eyepieces, so the binoculars' weight is rear biased for a more solid and ergonomic feel in the hand. The lightweight magnesium housing is wrapped in a slip-resistant elegant two-tone armor; and the optical tubes are nitrogen-filled and O-ring sealed to be resistant to internal fogging, as well as dustproof and waterproof. For long-duration observation sessions, the binoculars are tripod mountable to eliminate shake or vibrations, and reduce arm fatigue.

In the field, on the range, in a blind or up a stand, the 8x42 Primus binoculars are an ideal addition to your kit, for glassing without compromise.
