Echo Sounder · Navigation & Bridge Equipment
The Elac Nautik LAZ-5100 is a German‑made dual‑frequency echo sounder (50 kHz / 200 kHz) that provides accurate depth measurements for navigation and operational monitoring, with IMO type approval. The supplied category identifies the equipment as Echo Sounder, and it is normally installed on the bridge with the required external sensors, antennas, displays and data-network interfaces. In that listed 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. The model designation identifies the listed configuration, but no additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. The source metadata also states capacity: 50/200 kHz. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
