8.12 ACCU-FISH
™
The ACCU-FISH
™
feature, which requires an ACCU-FISH
™
capable transducer or
Bottom Discrimination Sounder FURUNO BBDS1 or Network Fish Finder FURUNO
DFF1-UHD, calculates the length of each fish and shows a fish symbol and depth val-
ue or fish length.
Usage guidelines
• The information given by this feature is intended for reference only.
• This feature cannot be used with the inside-hull transducer since a fish may not be
detected depending on the frequency of the transducer. Even if a fish is detected,
the fish length indicated may be smaller than the actual length.
• ACCU-FISH
™
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 menu.
• 50 kHz and 200 kHz beams are transmitted alternately without reference to the cur-
rent display mode.
• Use this feature with ship speed of 10 knots or less and depth between 2 and 100 m.
• 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.
