Echo Sounder · Navigation & Bridge Equipment
Kongsberg Maritime EA 440 Mk2 — Navigation & Bridge Equipment. As an Echo Sounder, it is normally installed on the bridge or in the navigation electronics system with its required external sensor, antenna or hull interface. In that role, its primary purpose is to provide bridge personnel and connected systems with vessel rotational or heading-related motion information. Unlike absolute heading sensors, a rate-of-turn indicator emphasizes rotational motion and depends on correctly scaled sensor input. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
