Description
Professional binoculars 10X50 with compass — the 10×50 Binoculars with Compass are binoculars with the magnification, objective-lens size, prism system, focusing controls, and available variant stated for this product. The binoculars are designed for maritime navigation and open-water observation. For orientation, these binoculars feature an internal directional compass with an illumination switch for low-light legibility. The left eyepiece incorporates a built-in stadiametric reticle. By using the crosshairs and the calculating dial located on the objective lens barrel, users can mathematically determine the distance to an object of known height or calculate the object’s size if the distance is known. Equipped with high-refractive BAK4 glass and Fully Multi-Coated (FMC) 50mm objective lenses, the optical system maximizes light capture, ensuring high contrast and minimal glare during dawn, dusk, or foggy conditions. Once set for the eyesight, the binoculars achieve infinite focus, keeping all objects from approximately 20 meters out to the horizon consistently sharp without requiring constant recalibration. The heavy-duty chassis is constructed from structural plastic steel wrapped in shock-absorbing rubber armor. It is O-ring sealed and nitrogen-purged to achieve an IPX7 waterproof rating, fully reducing internal fogging and mold regardless of humidity or sudden temperature changes. When used with a specialized floating strap, the unit is designed to remain buoyant if dropped overboard. Color: Black, Green, Colorful.
