The large 50mm diameter objective lens gathers more light for a brighter viewing, and offers a nice observation experience especially in low-light conditions like dusk or dawn, and for observing the night sky. 23mm eyepiece causes less eyestrain when observing.

There is one more option than the normal twist-up eyecups, so it is easier to adjust the most suitable distance between your eyes and the optical lens. Glasses wearers can adjust the eye cups up and down to reach a comfortable distance.

Fully Multi-coated Glass means all lens surfaces and all air-to-glass surfaces are anti-reflective multi-layer coated. The 50mm FMC lens increases the light transmission, delivers bright, clears and crisps images even in low-light conditions.

BAK4 has a high refractive index and lower critical angle, which means it transmits light better with less light being lost. The BAK4 offer you the superior brightness, resolution, and edge clarity.

The body is waterproof, which prevents itself from the moisture and dirt in the air, and with this waterproof binoculars, it is available to view the nature in drizzling days and lives a longer lifespan.
