Features

The JFC-130/130HP color echo sounder provides these features:
n Clear, High-brightness Display Pictures
· A 10.4-inch high-brightness, high-definition color TFT-LCD monitor provides clear, close pictures with
dramatically improved resolutions of 640 by 480 pixels.
· Four kinds of 16-color gradations and background colors are selectable. Day/night brightness selection is
available for all these kinds to support nighttime operations.
· A favorably received large fishfinder feature of user color creation is available to suit fishing grounds and
fish species.
n Ease of Operation
· A minimum set of keys are concentrated on the operator panel, with independent controls for gain control
and clutter control to fine-tune pictures according to waters, seasons, fishing methods, and so on.
· All functional settings are accomplished by easy menu selections. Settings may also be prerecorded to suit
fishing grounds and fish species. If a setting has been altered by mistake, a single key click can reset it to its
original value.
n Positive Monitoring of Surface Layer and Bottom Fish Schools
· A narrow zero line feature, coupled with a new transducer, narrows oscillation lines, to clearly monitor small
fish schools near the sea surface through high-speed transmissions at a rate of up to 600(JFC-130)/300(JFC-
130HP) cycles per minute. The BOTTOM LOCK EXPAND mode with 16-halftone colors precisely
discriminates between the sea bottom and bottom fish schools.
n More Numerous Features
· Simultaneous drawing
When the screen display mode is changed, the picture displayed so far appears momentarily to ease picture
comparison.
· A-scope display
An A-scope can be displayed in a split screen in which a single key click displays fish school echoes in
varying color tones and widths according to their intensity.
· Mixed display
A mixed three-display mode, consisting of a dual-frequency split display plus a mixed display makes it
easier to discriminate more fish specifies than before.
· Water temperature and depth change graphs (with alarms)
Fishfinding displays can be superimposed with graphs of water temperature and depth changes.
There is no need to keep the graphs on display at all times, since the water temperature and depth data is
stored in memory even while the graphs are hidden. Rather, a single key click manipulates the hidden graphs
into view.
