WÄRTSILÄ ELAC LAZ 5200 Echo Sounder | Marine Echo Sounder System | Digital Depth Sounder, Display Unit, Transducer, Spare Parts, Repair & Supply | SM MARINE SERVICE™
The WÄRTSILÄ ELAC LAZ 5200 Echo Sounder is a next-generation marine depth sounding system developed from the trusted ELAC Nautik echo sounding technology and integrated into the Wärtsilä marine product portfolio. Designed for commercial ships, offshore vessels, dredgers, research ships, and government fleets, the LAZ 5200 provides continuous, highly accurate water depth information for safe navigation.
Using advanced digital ultrasonic pulse-echo technology, the system measures the distance between the vessel's keel and the seabed with exceptional accuracy. Real-time depth information is displayed on a high-resolution color screen, enabling bridge officers to monitor under-keel clearance during coastal navigation, port approaches, anchoring, and shallow-water operations.
The LAZ 5200 combines reliable German engineering with a modern graphical user interface, making it a preferred choice for both new vessel installations and retrofit projects.
SM MARINE SERVICE™ supplies new, used, and professionally reconditioned WÄRTSILÄ ELAC LAZ 5200 Echo Sounder systems, including display units, processors, transducers, interface modules, power supply boards, spare parts, repair services, and worldwide technical support.

The WÄRTSILÄ ELAC LAZ 5200 is a professional marine echo sounder that continuously measures the water depth beneath the vessel using ultrasonic technology. It is an essential navigation instrument that helps bridge officers avoid grounding and maintain safe under-keel clearance while operating in restricted waters.
Unlike conventional analog echo sounders, the LAZ 5200 features a modern color display, digital signal processing, advanced alarm functions, and intuitive menu navigation. The system can present both numerical depth values and echo profiles, giving operators a clearer understanding of seabed conditions.
It is widely used on:
The ELAC LAZ 5200 operates using the internationally proven ultrasonic pulse-echo principle.
The operating process is straightforward:
This continuous measurement cycle enables safe navigation in shallow waters and provides reliable depth information under a wide range of operating conditions.
The WÄRTSILÄ ELAC LAZ 5200 Echo Sounder is built with advanced digital electronics and precision acoustic technology to provide continuous, highly accurate seabed depth measurements. Each module is engineered for reliable long-term operation in demanding marine environments.
The display unit provides real-time depth information, echo profiles, alarm indications, operating modes, historical depth data, and system diagnostics. Its high-resolution TFT color display ensures excellent visibility during both day and night bridge operations.
The processor is the core of the system. It generates ultrasonic transmission pulses, processes returning echo signals, performs digital filtering, calculates water depth, and communicates with the display unit.
Installed below the vessel's hull, the transducer converts electrical signals into ultrasonic sound waves and receives the reflected echoes from the seabed. Proper transducer performance is critical for maintaining accurate depth readings.
The DSP board amplifies weak echo signals, suppresses background noise, performs high-speed calculations, and ensures stable depth measurements under varying sea conditions.
The marine-grade power supply converts shipboard input voltage into stable operating voltages for all electronic circuits while protecting against voltage fluctuations and electrical disturbances.
The LAZ 5200 features programmable shallow-water and deep-water alarms to alert bridge officers whenever preset safety limits are reached.
The interface module enables integration with modern navigation systems such as:
Note: Specifications may vary depending on the installed software version, transducer type, and vessel configuration.
