Depth Contour Tracking, DCT
TM
If the system has input from an echo sounder, the autopilot can be set to follow a depth
contour.
Do not use this feature unless the seabed is suitable. Do not use it in rocky
waters where the depth is varying signicantly over a small area.

Use the following process to initiate DCT steering;
1 Ensure that you have depth reading on the NSE unit or on a separate depth
instrument
2 Steer the boat to the depth you want to track, and in the direction of the depth
contour (main course)
3 Activate AUTO mode, select DCT steering and monitor the depth reading
4 Use the Starboard or Port buttons to initiate the DCT steering depending on if the
bottom slopes to starboard or to port
The following parameters are available for DCT steering:
Turn parameter Range Change per step Default
Depth gain 5 - 95 5 5
Contour Cross Angle 0° - 50° 1 0
