PRE OWNED JRC JFE-680 JRC JFE-680 MARINE ECHO SOUNDER

The JRC JFE-680 is a professional-grade depth sounder designed to meet the rigorous safety standards of international shipping. It features a 10.4-inch high-visibility color TFT LCD that provides a detailed graphical echogram alongside large digital depth readings. The system's "History" mode allows the bridge team to review up to 24 hours of recorded depth data directly on the screen, fulfilling all SOLAS requirements for depth recording without the need for mechanical paper units.

Equipped with a highly sensitive transceiver, the JFE-680 can be configured for either 50 kHz or 200 kHz operation. The 200 kHz frequency is ideal for high-precision sounding in shallow coastal waters, while the 50 kHz frequency provides the power needed for deep-sea bottom tracking. Its flexible "Black Box" architecture allows for various installation options, making it a preferred choice for retrofitting modern bridges where space and visibility are top priorities.

KEY FEATURES & APPLICATIONS

-- High-Resolution 10.4" Display: The large, bright screen ensures that depth information and the historical seabed profile are clearly visible even from a distance on the bridge.

-- Advanced Paperless Recording: Stores a rolling 24-hour log of depth, time, and position data. This eliminates the maintenance of mechanical printers while ensuring full regulatory compliance.

-- Flexible Draft/Trim Correction: Features easy-to-use controls for inputting vessel draught, allowing the system to display either depth-below-keel or depth-below-surface.

-- Intuitive User Interface: Uses a combination of dedicated keys and on-screen menus for rapid adjustment of gain, range, and alarm settings.

-- External Interface Capability: Provides robust NMEA 0183 output for seamless integration with Voyage Data Recorders (VDR), ECDIS, and Integrated Bridge Systems (IBS).

-- Multiple Color Palettes: Includes specialized day and night viewing modes to optimize screen readability under all lighting conditions and protect the bridge team’s night vision.

TYPICAL CONDITION (USED/REFURBISHED)

Our refurbished JFE-680 units from the Alang yards undergo a strict multi-point technical inspection. We focus on the NWZ-158 monitor, checking for backlight consistency and pixel integrity. The Processor Unit is tested for stable frequency output and receiver sensitivity to ensure accurate readings in deep water. We specifically verify the NMEA data ports for signal stability, ensuring reliable data transfer to the ship's VDR. Every unit is factory-reset and provided with a detailed test report from our Bhavnagar facility.
