Why choose us 1-Portable：Binoculars are designed to be about the size of your hand and are easy to fit in your pocket or suitcase, making your trip a no-hassle experience. 2-Light and comfortable：The newer binoculars only weigh 280 gigabytes, so even long periods of use won't make your arms sore, which is impossible with regular binoculars. 3-High quality optical lenses:The lenses are coated with multiple layers of strong transmittance to correct the chromatic aberration of the light, so you can get a bright and realistic image. 4-Clearer:The advanced BAK4 prism provides better light transmittance, reducing the loss of light, so that the image is significantly brighter and clearer than the normal prism. 5-Anti-slip design:The rubber armor of the fuselage greatly increases the friction, making the grip more easy and stable, not easy to slide hands. This is the sincere suggestion from our professional binoculars team: 1-If you don't wear glasses, your vision may be clearer. 2-Please don't adjust the focus frequently, it will cause eye fatigue.
