This mark can be displayed with current indicator input. The tidal
current marks are displayed on the net shooting mark ( ) and net
sonde marks ( ). The tidal current markers shows tidal current
speed in three layers (1—3) selected on the tidal current indicator.
The tidal current speed is shown by the length of the tidal current mark.
Note however that no tidal current mark appears if the tidal current
speed is less than 0.2 kts. Current direction can be shown as "to" or
"from" by selecting CURRENT VEC-Current Flow Dir on the USER
menu. In the normal mode with text, speed, direction and depth of the
current are shown for three layers (C1, C2, C3). In the echo sounder
combination and history modes, only the speed appears (C1, C2, C3),
on the echo sounder combination or history display.
