display should be selected.
TRUE and RELATIVE can be selected by pressing the text or on the screen setup menu
Water current (WC)
The Dark blue arrow is the calculated current, this only shows direction as the current is normally small. The
arrow points in the direction the current flows (sets) This option is default off and can only be turned on if
there are a satisfactory number of calibrations (3).
If the bottom tracking of the system fails (too deep or poor signal) and a GPS input is connected, then this
display can be made to compensate the current using that signal.
Options:
This screen can show the resultant speeds of the vessel, and also the direction of the current. If a Gyro is
connected and activated, the angles will be true, if not they will be relative. The length of the vector in the
graphic to the left represents the speed. The Outer rim of the compass rose indicates maximum speed (the
speed is entered in the DL2 Menu)
