Keys and controls on the operation panel are minimized.Sensitivity,clutter rejection and STC are finely adjustable depending upon sea areas,seasons and fishing methods.

Three types of fishing ground or fish species can be present and stored.Once they are present,any type of fishing ground or fish species is selectable and can be reset to another type by pushing the CUSTOM button.

♦ Clear Detection of Surface and Bottom fish

 

The adoption of a narrow zero-line fuction and a new transducer makes the transducer line finer.The high-speed emissionof 600 (JFC-130) / 300(JFC-130HP) pulses or more per minute enables small fish in the surface water to be clearly detected.

The bottom enlargement display in 16 color gradations discriminates bottom fish from the sea bottom distinctly.

♦ Various Functions

 

Simultaneous display of two images

When an image is switched to another,two images are immediately displayed for ease of comparsion.

A-Scope Display

A fish echo is displayed in a color tone with a width depending upon its signal intensity.The display mode is turned on or off by a one key-touch operation.

Distinction (mix)mode

The three-split display mode in which a distinction display is added to the dual- frequency split display is very useful in discriminating fish species.

Water temperature and depth graphs

Water temperature and depth graphs can be displayed in overlay with a fish echo image.Since these temperature and depth variations are stored,the graphs may be easily displayed by one keyÅ] touch operation.

Normally,the fish echo image is displayed on a full screen.

Bottom discrimination mode

In the bottom lock enlargement mode,a long bottom tail shows a hard bottom (such as base rock)while a short bottom tail shows a soft bottom (mud and sand).Thus,the bottom topology can be discriminated depending upon the tail width.
