4. ECHO SOUNDER MODE
4-14
Fish histogram
The fish histogram shows, in graph form, signal strength distribution for the fish
school(s) marked with an estimate mark on the horizontal and echo sounder
displays. The histogram display for each of those displays will be different since
the calculation method is different. This data appears only when an estimate
mark is active. When two estimate marks are active histograms are displayed
one on top of the other as below.
The horizontal axis shows signal strength in 16 colors, and the vertical axis
shows fish school concentration inside the fish estimate mark. For the fish
estimate mark inscribed on the horizontal display the graph shows the average
movement in five scans, to increase accuracy.
Note:
The histogram display is redrawn five transmissions after a fish estimate
mark is erased and another mark of the same number is entered soon
after.
