Inspired by hunters, and outfitted with a high magnification that allows users to make detailed observations of distant subjects, Blaser 10x42 Primus Binoculars combine a slim ergonomic form factor with thoughtfully engineered optical features to give users an optic that is an ideal companion to today's long-range riflescopes.

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. These help 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, and in all light conditions. Complementing this are the contrast, Color Corrective Coating (CCC), and Smart Lens Protection (SLP) coatings. These further improve light transmission, color rendition, contrast, and clarity and help keep the lenses clear of water and debris, improving views and making cleaning easier. The generous field of view, combined with the long eye relief and comfortable exit pupil, help minimize the appearance of distracting hand shake commonly associated with high-power optics such as these, while presenting 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. They are 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 10x42 Primus binoculars give you the edge for identifying your target at a distance and the confidence to take the shot.
