1.
Operate the trackball to place the cursor on a school of fish, and then press the
ESTIMATE 1
key.
The estimate mark 1 appears on the school of fish. Relative volume is shown by
a figure between 0 and 100, below the estimate mark. When the area inside the
mark is filled in reddish brown, volume figure is said to be 100. When the estimate
mark is entered, a graph is shown at the histogram on the numeric/ graphic data
display.
2.
Operate the trackball to place the cursor on another school of fish, and then press
the
ESTIMATE 2
key.
Compare estimate figures for each school of fish by observing estimate mark data
and the fish histogram.
3.
To turn off the estimate marks press their respective keys.
Note:
The fish school mark and event mark 1 can be entered with the fish estimate
mark. For details, contact your dealer.
Fish histogram
The fish histogram shows, in graph form, signal strength distribution for the school(s)
of fish marked with an estimate mark on the horizontal 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 the
concentration of a school of fish 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.
