1.  OPERATION

The ACCU-FISH

TM

 feature measures the 

length of individual fish and tags the fish with 
a fish symbol whose size is proportional to the 
length of the fish. The length or depth of the 
fish can be indicated digitally. Connection to a 
transducer that supports ACCU-FISH

TM

 is re-

quired.

Note: The fish length calculated by this fish 
finder is intended for reference purposes; it is 
not a completely accurate measurement of 
fish length.

ACCU-FISH

TM

 is inoperative when the trans-

ducer type is selected to 600W or 1kW FCV-
587 only), on the [Transducer] menu.

1. Open the menu, select [Display] and 

press the ENTER key.

2. Select [ACCU-FISH] and press the EN-

TER key to show the [ACCU-FISH] menu.

3. Select [ACCU-FISH] and press the EN-

TER key.

4. Select [On] to enable ACCU-FISH

TM

.

1. Open the menu, select [Display] and 

press the ENTER key.

2. Select [ACCU-FISH] and press the EN-

TER key to show the [ACCU-FISH] menu.

3. Select [Fish Symbols] and press the EN-

TER key.

•  The 600 W transducers which support 

ACCU-FISH

TM

 are 520-5PSD, 520-5MSD, 

525-5PWD, 525STID-MSD and 
525STID-PWD.

•  To display fish marks and fish size using a

1 kW transducer, the integrated transducer 
50/200-1T or 50/200-12M is recommended.

•  Echo intensity depends on fish species. 

When the fish length differs between the in-
dicated length and the actual length, you 
can compensate the difference on the
[Calib] menu (see section 2.6).

• ACCU-FISH

TM

 is inoperative when the zero 

line rejector is active.

•  High and low frequencies are alternately 

transmitted when ACCU-FISH

TM

 is active, 

regardless of mode selection.

•  A fish whose depth is shallower than 2 m or 

greater than 100 m cannot be measured.

•  If the transducer is installed inside the hull, 

the signal is attenuated by the hull. There-
fore, a fish may not be detected or the fish 
length indicated may be shorter than actual 
length.

•  In a school of fish, echoes overlap one an-

other, so the margin of error will be greater.

•  The bottom echo must be present to show 

the fish symbols.

•  The TX pulse length changes according to   

ACCU-FISH

TM

 On/Off state. This causes a 

difference in both sensitivity and the echoes 
viewed.
