The BRESSER Topas 7x50 is a classic marine binocular with porro prisms. The optics provide good twilight performance, and 7x magnification is the proven standard for this type. The waterproof, ergonomic rubber-covered, impact-resistant binoculars allow you to get a sharp image at all relevant nautical distances with a single adjustment of the unique eyepiece focus. Eyecups allow eyeglass wearers to use the entire field of vision. Using BAK-4 glass and multi-layer coating, this binocular always provides a clear, high-contrast image. Lens caps are attached to the straps to prevent loss, plus the neck strap floats if dropped into the water. In addition, the scope has a built-in and illuminated magnetic compass and a reticle that can be used to determine size or distance using the ring scale on the tube.
