Echo Sounder · Navigation & Bridge Equipment
The JRC JFE-680A is a dual‑frequency echo sounder (50 kHz / 200 kHz) designed for accurate depth measurement down to 3000 m, primarily used for deep‑sea navigation and positioning. As an Echo Sounder, it is normally installed on the bridge with the required external sensors, antennas, displays and data-network interfaces. In that role, its primary purpose is to provide navigation, position, heading, speed, depth, traffic or bridge-management information according to the listed category. Radar, ECDIS, gyrocompass, GNSS, speed log, echo sounder and integrated bridge systems use different sensing principles, so calibration and interfaces must match the actual installed equipment. Capacity: 50/200 kHz / 3000 m. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
