Trinovid 10x25 BCA

Compact Binoculars

Inspired by their iconic full-sized counterpart, the Leica 10x25 Trinovid BCA Binoculars deliver the performance users have come to expect from the brand, but in a highly portable and easy-to-carry design. Designed with a combination of phase-corrected BAK4 roof prisms, the proprietary HighLux system, and HDC fully multi-coated optics to produce bright and clear colour-neutral images, while fitting comfortably in the hand for long, fatigue-free glassing sessions. The HDC coatings add abrasion-resistance to protect the exterior lens surfaces, and the lenses are also treated with AquaDura coatings, which make them easy to clean dirt, grime, oils, sap, and fingerprints without leaving residues that can interfere with views.

Designed to easily fit in a pocket, pack, or purse, the binoculars are made with a dual-hinge system that allows the optical tubes to fold and tuck under the closed bridge to ensure the smallest form factor when fully closed. This also provides a wide interpupillary distance adjustment for easier use by those with narrow faces—like children and adolescents. Helping to reduce the weight to a mere 9 ounces is an aluminium alloy chassis that is wrapped in a protective slip-resistant armour for a more comfortable feel in the hand. Light, compact, and easy-to-use while delivering bright and clear images, the Trinovid BCA binoculars are made to be your constant companion on the trail, at the stadium, or sightseeing around the world.
