7.10 ACCU-FISH
TM
The ACCU-FISH
TM
feature estimates the length of each fish and shows a fish symbol
and depth value or fish length. This feature requires appropriate transducer and either
Network Sounder BBDS1 or DFF series.
Application consideration
The information given by this feature is intended for reference only.
• ACCU-FISH
TM
uses both low and high frequency echoes for the measurements re-
gardless of the frequency mode in use.
The intensity of an echo depends on fish species. If the indicated length is different
from the true length, you can apply an offset in the [Sounder] - [ACCU-Fish Size
Correction] menu of the main menu.
50 kHz and 200 kHz beams are transmitted alternately without reference to the cur-
rent display mode.
To reduce the error, the detection area must be 2 to 100 meters from the surface.
The signal attenuation on the inside-hull transducer is different between 50 kHz and
200 kHz. This attenuation causes some fish to get ignored and the fish length indi-
cated can be shorter than the true length.
Echoes from a school of fish can be in more than one layer, which can cause wrong
length indication.
The fish symbol indication is not shown when the bottom echo does not appear on
the screen.
