Watch Out for Too Small Objective Lens

The smaller of the objective lens, the narrower of view width, but the lighter of the weight, so it’s not saying that a smaller diameter objective lens is not good. When you want to watch a concert or hiking, it’s really need a smaller and lighter binoculars.

But if you need to observe more objects or scenes or huntings, you need a binoculars with a diameter of 42mm or more, because the 42mm one can maintain the stability of the binoculars while having a more wide field of view and sufficient light brightness.

Multi-Coated Green Film

The green film is a common multilayer film, and the AR passband is wider.
The multi-layer film can well eliminate the enlarged color deviation of the scene for many rays of light, and improve the brightness of observation.

BAK-4 Roof Prism

Roof Prism keeps outgoing and incident light in a straight line. Its lens barrel is straight, and the sense of distance, stereo vision, and size are also closer to the naked eye.
BAK-4 glass is finer (higher density), it can eliminate internal light divergence, and it is clearer than BK-7 glass imaging.

Double Glue Achromatic Lens

Different glasses have different light dispersion properties, so two different glasses will be used on a lens and bonded with a “photosensitive adhesive” dedicated to precision optical components, so that all chromatic aberrations can be neutralized.

How to Use Binoculars?

Step 1: Rotate and raise the eye cup

This is to ensure the distance between the eyepiece and the eye, so that the light can reach the pupil smoothly.

Step 2: Adjust the central wheel and and distance of two lens cones

Adjust the central wheel until the sight get clearly.
Adjust the central distance of two lens cones until see a circular field of view.

Step 3: Adjust the right eye wheel

If the left and right eyes have different vision, you can eliminate the difference by adjusting the right eye parallax wheel. Just turn the wheel until your eyes are fully visible.

Attention: No need to raise eye cup when wearing glasses

Since the glasses and the eyes have been kept at a certain distance, it’s not necessary to raise the eye cups when using it, otherwise the distance of the light reaching the eyes will not be enough.
