In both 15x and 18x options, the B.5 is our most powerful binocular and the fluorite glass is a step above ED glass of similar-sized optics. One of the most modern optical systems on the market, this purpose-built binocular is designed to extend your range for those who require increased magnification and for discerning detail during those critical low-light periods when covering big, open country. And when paired with an ultralight tripod setup, this binocular is your answer to a lightweight rig when carrying your spotting scope is out of the question.

Bright from first light to last, this binocular performs similar to larger objective optics, but is housed in a smaller package allowing
for easier packability and an enhanced glassing experience.

Just like the entire B Series line-up, the B.5 offers superior low-light performance, tack-sharp edge-to-edge clarity, generous depth of field,
and considerable eye relief. To top it off, the B.5 is fully customizable to match your specific needs.
