Maven C.4 56mm ED Binocular 18×56

The Maven C.4 is a high-magnification binocular developed for observing distant animals, birds and targets across wide-open terrain.

Its large 56mm objective lenses gather more available light, while extra-low-dispersion glass helps reduce colour fringing and preserve fine detail. Dielectric-coated, phase-corrected Schmidt-Pechan roof prisms deliver bright images with natural colour and strong contrast.

The nitrogen-purged body is fog-resistant and rated IPX7 waterproof. A durable polymer frame provides dependable protection for demanding outdoor use.

Both magnification options are best used from a tripod. The 15×56 offers a slightly wider field of view, while the 18×56 provides maximum magnification for identifying fine details at extended distances.

Choosing your magnification:

• 15×56: High magnification with a wider 215ft field of view and 17.4mm eye relief.
• 18×56: Maximum long-distance detail with a 194ft field of view.
