Maven B.5 56mm Fluorite Binocular – 12×56 Orange Grey

The Maven B.5 is a high-performance binocular built for hunters, wildlife observers and long-range shooters who require increased magnification without carrying a full-size spotting scope.

Its large 56mm objective lenses collect plenty of available light, while premium fluorite glass helps reduce colour fringing and reveal fine detail at extended distances. Phase-corrected Abbe-Koenig prisms and a field-flattening optical system produce a bright, high-contrast image with excellent clarity across the field of view.

The lightweight magnesium chassis is nitrogen purged and IPX7 waterproof for dependable performance in changing weather conditions. Due to the high magnification, tripod mounting is strongly recommended—especially with the 15×56 and 18×56 models.

Choosing your magnification:

• 10×56: Best for maximum low-light performance and a wider field of view.
• 12×56: A balanced option for hunting and longer-distance observation.
• 15×56: High magnification for identifying distant animals and targets.
• 18×56: Maximum detail at extended distances; tripod use is recommended.
