The BRESSER Topas 7x50 is a classic marine binocular with porro prisms. The optics provide good twilight performance and the 7x magnification is the proven standard with this application. In addition, the Topas has an integrated and illuminated magnetic compass and a reticle for determining sizes or distances with help of the ring scale on the objective barrel. The binoculars are waterproof. Due to its ergonomic rubber armouring it has a good grip and is also protected against shocks. With the individual eyepiece focus once set you can get a sharp image for all relevant nautical distances. Foldable eyecups allow spectacle wearers to use the entire field of view. By using optical BAK-4 glass and a multi-layer coating these binoculars always provide a bright, high contrast image. The lens caps are secured to the straps to prevent loss. A tripod mount is available. Likewise, a flotation is for the case that the good piece should go over board. end tab Features Solid marine binoculars ideal for observations while sailing or for other water sports Built-in, illuminated compass and reticle for navigation and distance measurement Field of View: 116m/1000m; Light intensity: 27.56 Binoculars Dimensions: 195x197x80 mm, Weight: 1185 g Waterproof and shockproof Bright and high contrast images Ergonomic design Suitable for spectacle wearers Includes: binoculars, flotation strap, case, lens cloth, 2x LR43 batteries, manual end tab Specs Item Number 18?66932 Magnification 7 Field of View 116 m/1000 m Lens Coatings multi-coated Eye Relief mm Exit Pupil mm Focuser Type individual eyepiece Dimensions 195x197x80 mm Brightness 27.56 Objective Lens Diameter 50 mm Apparent Field 6.63?
