Product Information
YJM98-1050 binoculars are used to observe, search and monitor objects at a distance during the day, and can be used to measure the direction Angle, height Angle and distance of the target. It has the advantages of wide visual field, large exit pupil diameter and long exit pupil distance. It is obviously superior to similar telescopes in brightness, image quality and color authenticity. It can also see the target clearly and comfortably in low-light environments such as dusk and dawn and under the condition of wearing a gas mask (or glasses)
