According to product information, series is the next generation of Furuno marine echo sounder systems, suitable for merchant ships, cargo ships, passenger ships, service vessels, offshore vessels, and vessels requiring depth measurement equipment that can connect to modern bridge systems.

Dual Frequency Depth Display 50/200 kHz

FURUNO FE-800 supports dual frequency display of 50 kHz and 200 kHz when connected to two transducers. In this configuration, the device can simultaneously display the depth at the FOREand in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.AFT positions, allowing operators to better monitor the clearance ahead and astern of the vessel during maneuvering.

series offers configurations for different needs. According to product information,50 kHz frequency is generally more suitable for deep water or conditions requiring good penetration, while 200 kHzsuitable for shallow water, providing better resolution at short range. The actual configuration depends on the type of transducer, installation location, and vessel requirements.

8.4-inch high-contrast color LCD screen

The FE800 is equipped with a color screen8.4-inch LCD color screenhigh contrast, which displays the echogram, depth data, and operational information clearly in the cockpit. Furuno specifications indicate the screen has a resolution of640 x 480 VGA, displays echoes in multiple colors and supports different background/text colors to suit viewing conditions.

The color screen allows the operator to easily monitor seabed variations, recognize depth trends, and observe data in various display modes.

Multiple display modes: NAV, OS DATA, and HISTORY

Furuno FE800offers multiple display modes, includingNAV, OS DATAand in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.HISTORY. TheNAVmode displays sounding data for navigation; theOS DATAmode displays vessel data when connected to an external GPS navigator; andHISTORY allows viewing recorded echo/depth data over time.

When connected to a GPS navigator, the Own Ship Data -- OS DATA screen can display information such as position, time, and related navigation data, assisting marine officers in monitoring the vessel's status within a single interface.

24-Hour Depth Data Logging

The FE800 is capable of logging depth data for 24 hoursAccording to Furuno documentation, the system can store and replay data at recording intervals such as5 seconds, 1 minute, or 2 minutes, corresponding to approximate data storage/replay durations of 1 hour, 12 hours, or 24 hours.

. This feature is particularly useful for reviewing sounding data during a watch, post-voyage cross-referencing, technical reporting, or supporting analysis when the vessel traverses shallow waters.

Logbook Stores Up to 720 Entries

series offers configurations for different needs. According to product information,The features a features a 720 log entries720 log entries

The Logbook is an important function for vessels that need to record depth data with associated time and position, assisting with the nautical log, operational checks, and post-voyage data comparison.

The Alert Log List stores up to 100 alerts

The FE800 has a listAlert Log List to display the alert history. The Furuno brochure describes the alert list as capable of holding up to100 alerts, allowing the operator to review past alerts during operation.

The device generates an alert when the depth below the transducer is lower than the set threshold. Additionally, if bottom loss occurs due to out-of-range scaling or signal degradation, the system can also issue an alert for the operator to check in a timely manner.

Bridge Alert Management – BAM ready

A key advantage of theFuruno FE800is its ability to meet alarm requirements and integrate withBridge Alert Management – BAMper IMO MSC.302(87). This makes the device more suitable for modern bridge systems where alarms need to be centrally managed and clearly classified.

According to Furuno's current product page, the FE-800 is also listed asCompliant with IACS UR E27, indicating that the device is updated with newer maritime industry requirements and standards.

Remote Display Connection RD-20/RD-50

When connected to theFURUNO RD-20MX575C DGPS CompassRD-50 remote display, depth data from the FE800 can be observed at a remote location. This feature is suitable for vessels that need to display depth in multiple locations such as the main bridge, bridge wings, control room, or other operating areas.

Supports PC printer and data logging software

The FE800 has an optional printer interface for printing echograms. Additionally, when a PC is connected with optional data logging software, the operator can save, compile, and print recorded echogram data via the computer.

This option is particularly suitable for vessels that need to keep depth measurement records, for internal surveys, class inspections, voyage analysis, or post-trip technical reports.
