The Bresser Topas Compass 7x50 Porro prism binocular is a beautiful waterproof binocular designed specifically for the nautical/water sports market. With 7x magnification, it is ideal for looking up buoys, other ships and bridges, even during storms when it is normally difficult to keep binoculars steady. With a lens diameter of 50 mm, the binoculars are very bright and can be used at night during clearings. These binoculars have an exit pupil of 7.15 mm, exactly the same size as that of the human eye. This means that the full light intensity can be utilized from the binoculars and no light is lost. The eyecups can be easily folded back, allowing spectacle wearers the full field of view. Focusing is done through both eyepieces.Once focused at a distance of about 20 meters, the binoculars are sharp to infinity and you do not need to adjust.

The viewer has an illuminated 360° compass which can be used for navigation, checking other vessels, detecting any collision course at an early stage and with the help of the rotating distance ring around the right objective tube, distance can be estimated and height can be calculated to see if you can pass under a bridge.

The body is nitrogen-filled which makes it waterproof and does not fog up from the inside. The viewer is threaded at the front on the center axis, making it easy to mount on any camera tripod using a tripod adapter.
A yellow float strap is included, if the viewer accidentally falls into the water it will stay afloat on the strap.
