ELAC LAZ 5100 Echo Sounder | ELAC Echo Sounder System | Marine Depth Sounder, Transducer, Display Unit, Spare Parts, Repair & Supply | SM MARINE SERVICE™
The ELAC LAZ 5100 Echo Sounder is a high-performance marine depth sounding system developed by ELAC Nautik GmbH, Germany, a globally respected manufacturer of hydrographic and marine navigation equipment. Designed for commercial shipping, offshore vessels, naval ships, and research vessels, the LAZ 5100 provides continuous and highly accurate water depth measurements to enhance navigational safety.
The system uses advanced ultrasonic pulse-echo technology to measure the distance between the vessel's keel and the seabed. A hull-mounted transducer transmits acoustic pulses into the water and receives the returning echoes, while the processor calculates the exact depth and displays the information in real time on the bridge.
Known for its German engineering, reliable operation, and robust construction, the ELAC LAZ 5100 is widely installed on vessels that require dependable under-keel clearance monitoring in ports, coastal waters, rivers, channels, and offshore operations.
SM MARINE SERVICE™ supplies new, used, and professionally reconditioned ELAC LAZ 5100 Echo Sounder systems, including display units, processor units, transducers, power supply modules, interface boards, spare parts, repair services, and worldwide technical support.

The ELAC LAZ 5100 is a professional marine navigation instrument that continuously measures and displays the water depth beneath a vessel. It is designed to help bridge officers maintain safe under-keel clearance and avoid grounding during navigation in shallow waters and restricted areas.
Unlike manual sounding methods, the LAZ 5100 automatically provides continuous digital depth information with high accuracy and fast response. This makes it an essential navigation aid for commercial ships operating in ports, coastal waters, rivers, dredging zones, and offshore projects.
The system is suitable for both new vessel installations and retrofit applications and can be integrated with other bridge navigation equipment to improve operational awareness.
The ELAC LAZ 5100 Echo Sounder operates using the internationally proven ultrasonic pulse-echo principle.
The operating sequence is as follows:
This cycle repeats continuously, providing accurate real-time depth information regardless of vessel speed or normal sea conditions.
The ELAC LAZ 5100 Echo Sounder is designed with precision electronic and acoustic modules to deliver continuous, highly accurate, and dependable seabed depth measurements. Every component is engineered to withstand demanding marine environments while ensuring reliable long-term operation.
The display unit provides real-time water depth, echo profile, alarm status, operating modes, and system diagnostics. Its high-contrast marine display ensures excellent readability in bright daylight, nighttime operations, and adverse weather conditions.
The transceiver serves as the central processing unit. It generates ultrasonic transmission pulses, receives reflected echoes, processes acoustic signals, calculates water depth, and communicates with the bridge display.
Installed below the vessel's hull, the transducer converts electrical pulses into ultrasonic sound waves and receives the reflected echoes from the seabed. Proper transducer performance is essential for achieving accurate depth measurements.
The signal processing board amplifies weak echo signals, removes background electrical noise, performs digital filtering, and ensures stable, high-precision depth calculations.
The marine-grade power supply converts shipboard input voltage into stable operating voltages for all electronic circuits while protecting the system from voltage fluctuations and electrical disturbances.
The LAZ 5100 incorporates programmable shallow-water and deep-water alarms, enabling bridge officers to receive immediate warnings whenever preset safety limits are exceeded.
The communication interface enables integration with modern navigation equipment, allowing depth information to be shared with Integrated Bridge Systems (IBS), Voyage Data Recorders (VDR), navigation computers, and other compatible marine systems.
Note: Specifications may vary depending on software version, transducer type, and vessel configuration.
