About this item

【Equipped with BAK-4 Porro Prism】：High refractive index to eliminate stray light and increase the color reproduction to 99.99%. The green FMC coating can reduce the reflected light in the objective lens and improve the light transmittance, image brightness and image clarity. The 50mm objective lens and 23mm eyepiece with high-definition wide-angle vision function can more easily see distant objects without causing eye fatigue and dizziness.

【IPX7 Waterproof】：The binoculars are equipped with nitrogen-filled waterproof and fogproof design. The O-ring seal is completely waterproof and can float on water, so there is no need to worry about falling into the water; it is purged and sealed with dry nitrogen to prevent mist and moisture from being generated in any weather conditions, and it is very durable.

【Rangefinder and compass】: The binoculars have a built-in illuminated compass for direction positioning. The built-in rangefinder can directly calculate the distance and size of the object on the right eyepiece. In low light conditions, the ruler and compass can be illuminated by light. (Please note: it will not work in all dark environments.)

【Focusing system】: With ±5 diopter left and right diopter rings, you can adjust the distance to get a better viewing effect and precise focus without glasses.
