BELONA BL-01 Binoculars It is an metal + environmental protection rubber skin with very good feel and durability.

BAK4 Prism material, coating system FMC Full Broadband Multilayer Coating It is HD.Visible at low light.

It adds the function of adjusting the binocular parallax, you can turn the central control valve to adjust the left eye to focus, and then turn the fine adjustment valve of the right eyepiece to focus the right eye. This solves the problem that the left eye is clear and the right side is blurred when looking at the telescope due to different binocular vision.

It also designed a swivel eyecup, which is rotated to the left, and the eyecup extends a certain distance outward. The eyes can be attached to the eyecup to reduce the image shake caused by hand shake. Such telescopes have become very popular with us. So the product is very mature.
