FCV-38: the new black-box Split-Beam echo sounder for professional use
We are pleased to introduce the FCV-38, which is successor of the FCV-30. The FCV-38 is designed as a high-end echo sounder having a fish size graph function with split-beam technology.
A unique sharp beam of 38kHz low frequency and 4 kW high power allow obtaining the clear echo image of a school of fish and seabed even in the deep sea.
Multi-directional split-beam technology
The FCV-38 can detect school of fish in five directions at once and provides information on the location of the targeted fish in relation to the vessel. The operator can adjust the five beams in any direction within a 20 degrees range in the menu settings.
For five beam transmission, you can freely activate or deactivate simultaneous transmission and adapt it to your needs by using three types of split-beam mode* in the setting menu: Alternating transmission, Semi-simultaneous and simultaneous transmission.
Semi-simultaneous transmission is new function which limits beam-to-beam interference and makes the seabed easier to identify than with the simultaneous beam transmission mode.
The timing of the transmission has been optimized to accelerate the transmission cycle of the beam even with 5 beams.
Accurate fish size measurements
The FCV-38 measures the size of fish in the selected area, and displays the information in a graph that can be understood at a glance. The split-beam technology has improved the accuracy and reliability of fish size measurements and graphs (max. 3).
By analyzing the size, volume and movement of a targeted school of fish, operators can easily decide what to catch and what not to catch. It is indispensable for deciding when to go for a catch and eliminate a school of fish that are smaller than desired. In addition, it greatly contributes to the management and study of fisheries resources.
Other functions
Built-in motion sensor
Pitching and rolling produces adverse effect not only on the sounding image, but also on measurement of fish size. With #furuno exclusive Stabilizer Technology, the FCV-38 can stabilize both TX and RX beams independently so that the picture will remain accurate.
Scientific data output
The output of scientific data in netCDF4 format will contribute to fish stock assessment etc. Data analysis software that can read data in netCDF format is currently being developed in some institutes.
Easy and quick operation
The FCV-38 can be operated easily and quickly with its trackball. The screen header also contains Range, Shift, Sensitivity, Image Feed, and Display Mode menus that can be immediately accessed when required. Other functions can also be accessed immediately by setting them in the Instant Access barTM as desired.
Screenshots and echo data can be recorded and play back
A maximum of 99 screenshots can be saved on the processing unit. You can also replay the echo display at any time if you wish to see it again.
This is helpful in comparing the sizes of schools of fish. For external memory devices, the number of files that can be saved depends on the capacity of the device.
Scroll back mode allows you to view past screens of fish finder images, making it handy for comparing the sizes of schools of fish close to each other.
