Bresser Topas 7x50 Binoculars Compass Blue

The Bresser Topas Compass 7x50 Porro prism binoculars are high-quality, waterproof binoculars specifically designed for the nautical/watersports market. With a 7x magnification, they are ideal for spotting buoys, other ships, and bridges, even during stormy weather. Featuring a 50mm lens diameter, the binoculars are very bright and can also be used at night in clear skies. The binoculars have an exit pupil of 7.15mm, which is the same size as the human eye, ensuring full light utilization and no light loss. The binoculars have fully diopter-adjustable LE (Long Eye) eyepieces with eyecups, allowing them to be adjusted to your personal vision. The eyecups can be easily folded back, so spectacle wearers can also see the full field of view. Focusing is done via both eyepieces, and once focused at a distance of approximately 20 meters, the binoculars remain sharp to infinity without needing to be readjusted. The binoculars are equipped with an illuminated 360° compass that can be used for navigation, monitoring other shipping, and early detection of potential collision courses. With the aid of the rotating rangefinder scale on the right objective barrel, the distance can be estimated, and the height calculated to determine if you can pass under a bridge. The binoculars are filled with nitrogen, making them waterproof and preventing internal fogging. A thread on the front of the binoculars allows for easy mounting on any camera tripod using a tripod adapter. A yellow floating strap is included, so the binoculars will float if accidentally dropped into the water.
