This is a metal + environmentally friendly rubber skin binoculars, has a good feel and durability.
It is a 42MM diameter objective lens with a large field of view.
BAK4 mirror lens material, FMC full broadband multilayer green coating, has good light transmission effect, and has low light night vision function.
It adds the function of adjusting binocular parallax. You can turn the central control valve to adjust the focus of the left eye, 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 the telescope is fixed due to the difference in binocular vision.
