JRC JFE-380 Echo Sounder | Marine Echo Sounder System | Depth Sounder, Transducer, Display Unit, Spare Parts, Repair & Supply | SM MARINE SERVICE™
The JRC JFE-380 Echo Sounder is a high-performance marine navigation instrument developed by Japan Radio Co. (JRC) for accurate and continuous water depth measurement. Designed for commercial vessels, offshore platforms, passenger ships, and government vessels, the JFE-380 provides reliable real-time seabed information that enhances navigational safety.
The system measures the distance between the vessel's keel and the seabed by transmitting ultrasonic sound pulses through a transducer installed below the hull. The reflected echoes are processed and displayed on a high-resolution LCD screen, allowing bridge officers to monitor water depth continuously during navigation.
The JFE-380 is widely recognized for its excellent reliability, intuitive user interface, robust construction, and long operational life. It complies with international marine navigation requirements and is suitable for operation in both coastal waters and deep-sea voyages.
SM MARINE SERVICE™ supplies new, used, and professionally reconditioned JRC JFE-380 Echo Sounder systems, including displays, processor units, transducers, interface boards, cables, spare parts, repair services, and worldwide technical support.

The JRC JFE-380 Echo Sounder is an advanced depth measurement system that enables navigators to determine the water depth beneath the vessel in real time. It operates using ultrasonic pulse-echo technology, where sound waves are transmitted downward through the ship's transducer. When these sound waves strike the seabed, they are reflected back to the transducer and processed by the system to calculate water depth accurately.
Unlike traditional sounding methods, the JFE-380 delivers continuous digital depth information with high accuracy and fast response times. This capability is essential for vessels operating in shallow waters, approaching ports, navigating rivers, or conducting offshore operations where under-keel clearance is critical.
The system is commonly integrated with other bridge navigation equipment, allowing officers to maintain situational awareness and reduce the risk of grounding.
The JRC JFE-380 operates based on the pulse-echo principle:
This measurement process repeats continuously, providing real-time depth information regardless of vessel speed or sea conditions.
The JRC JFE-380 Echo Sounder consists of several precision-engineered modules that work together to provide continuous and accurate depth information.
The display unit presents real-time water depth, echo returns, seabed profile, alarm status, and system settings. Its high-contrast LCD ensures excellent visibility in both daylight and nighttime bridge operations.
The processor unit is the heart of the system. It generates ultrasonic transmission pulses, processes the returning echoes, calculates the water depth, and communicates with the display.
Installed below the vessel's hull, the transducer converts electrical signals into ultrasonic sound waves and receives the reflected echoes from the seabed.
Provides stable operating voltage and protects the electronic modules from voltage fluctuations common in marine electrical systems.
Processes weak echo signals, filters electrical noise, and improves depth measurement accuracy.
The system can generate audible and visual alarms whenever the vessel reaches preset shallow-water or deep-water limits.
Supports integration with bridge navigation equipment through standard marine communication interfaces, allowing depth information to be shared with other onboard systems.
Note: Specifications may vary depending on software version and vessel configuration.
