Maven B.1 Binocular 10×42 Orange

The Maven B.1 combines premium Japanese optical components with a strong magnesium chassis to provide clear, dependable performance in demanding outdoor conditions.

Its extra-low-dispersion glass helps reduce colour fringing and preserve fine detail, while dielectric-coated Schmidt-Pechan roof prisms support bright, accurate images. Choose the 8×42 model for a wider field of view and comfortable observation, or the 10×42 model for increased magnification and greater long-distance detail.

The nitrogen-purged body is rated IPX7 waterproof, helping prevent internal fogging and protect the binocular during wet-weather use. Multi-position eyecups, a ±3 diopter adjustment and a broad interpupillary range allow the binocular to be configured for different users.
