About This Model
The Maven B1.2B1.2 8×42 ED is a premium binocular developed for birdwatching, wildlife observation, and extended use in the field. Its 8× magnification and 42 mm objective lenses provide a versatile combination for locating subjects and observing fine details.

The 18.1 mm eye relief and 4.9-foot close-focus distance add useful specifications for different viewing situations.
Built for changing outdoor conditions, the B1.2 features nitrogen-filled, waterproof construction tested to the IPX7 standard. The manufacturer lists a magnesium frame, multi-position eyecups, and tripod compatibility among its design features.
