ELAC LAZ5100 Echosounder is a marine echo sounder designed to provide reliable depth information for vessels during navigation. The device is the successor to the LAZ 5000 series, developed to meet the depth measurement needs from shallow to deep waters, while supporting new installations or upgrades of existing echo sounder systems on ships.

According to the technical documentation, LAZ 5100 / ES 5100 is a compact, processor-controlled echo sounder system that displays depth on an LCD color screen and features a menu structure to assist users in setting operating parameters.

Paperless, compact, low-maintenance design

ELAC LAZ 5100 is a A dedicated marine echo sounder for safe navigation. echo sounder system, which reduces consumable costs and limits the mechanical issues commonly found in traditional paper echo sounders. The device has no moving parts in the paper recording mechanism, thereby reducing maintenance needs and making it suitable for modern navigation systems on ships.

The device displays depth as a color echogram and numerical values, allowing the operator to observe the seabed trend and quickly read the current depth value. The technical documentation describes the depth displayed on the LCD color screen as depth below keel – DBK.

Single frequency or dual frequency version

LAZ 5100 can be configured as a single frequencyMX575C DGPS Compassdual frequency, depending on installation needs and the type of transducer used. The single-frequency version is suitable for basic depth sounding configurations, while the dual-frequency version offers users more flexibility when combining long-range depth sounding with good resolution in shallow waters.

The system can operate with transducers at various frequencies, from 24 kHz to 200 kHz. Some common frequencies include 24, 28, 30, 33, 38, 50, 100, and 200 kHz.

With a maximum measurement range of approximately 2 km, the system effectively meets navigation needs in diverse water areas, from coastal zones, port channels, anchorage areas to deep waters.

10.4-inch color TFT display

LAZ 5100 uses a 10.4 inch TFT, displaying echograms, digital depth, and related navigation information. The large screen allows operators to easily view depth measurement data in the cockpit, especially when continuous monitoring of the seabed topography is required in shallow waters or maneuvering areas.

The brochure also describes the system as having a 10.4-inch high-resolution display, showing depth in a color echogram along with the vessel's position, date, and time.

24-hour data memory

ELAC LAZ5100 has a data memory for 24 hours, used to store depth, position, date, and time information. This function allows operators to retrieve recorded depth measurement data from the current shift or the most recent voyage.

The user manual also describes the LOG DATA MENU allows access to data stored in the system's integrated 24-hour memory.

NMEA 0183 etc 61162-1 connection

LAZ 5100 supports depth data communication according to the standardNMEA 0183 / DIN EN 61162-1, with data sentences such asDPT, DBT and the formatELAC. This facilitates easy connection of the system to other maritime equipment such as ECDIS, VDR, repeaters, alarm systems, auxiliary displays, or integrated bridge systems.

The technical documentation also states that the serial interfaces useRS-422, and NMEA devices connected to the echo sounder must have a compatible RS-422 interface to avoid damaging the communication circuitry.

Optional printer data output

Current and stored data can be printed when the system is connected to an optional printer. This feature is useful for vessels requiring log keeping of sounding data, shift data verification, or printing echograms for technical reports.

The user manual describes the hard copy function of the echogram when a printer is connected to the system, and that markers on the screen can store relevant information into the 24-hour memory.

Meets IMO requirements for maritime echo sounders

ELAC LAZ 5100 is designed for maritime navigation applications and meets IMO requirements for navigation echo sounders. The brochure clearly states that the device meets IMO requirements for navigation equipment and is type-approved by authorities such asBSH, USCG, and CCS.

The technical documentation also states that the system is certified to meet the requirements according to The technical documentation also notes that the system is certified to meet the requirements of , and the Wheelmark test is certified by , and that Wheelmark testing was certified by .
