Bottom discrimination display
The bottom discrimination display, which requires a bottom discrimination capable
transducer or Bottom Discrimination Sounder FURUNO BBDS1 or Network Fish Find-
er FURUNO DFF1-UHD, identifies probable bottom composition. The display is avail-
able in all screen divisions, single or dual frequency mode, and occupies the bottom
1/6 of the screen in the full screen display.
Use this feature with ship speed 10 knots or less and depths between 5 and 100 m.
Note 1:
Composition estimate accuracy may be affected when the transducer is not
parallel with the seabed.
Note 2:
When the bottom discrimination feature is active, picture advance speed may
be affected.
