Flattering to the eye //

In accordance with the international COLREG 1972, the frequency spectrum of our sound signalling systems ranges from 70 Hz to 370 Hz. The range of our standard horns is the basis for individual solutions that lead to unique sounds. The finely tuned sound is complemented by the elegant design. We are manufacturers of sound signalling systems with highly polished materials, high-quality chrome-plated or nano-coated surfaces. The design in the perfect colour to match the ship and the accomplished shape blend elegantly into the overall appearance. This is how you achieve a perfect look for your yacht.
