Depth Contour
Steering to a depth contour is also an AUTO mode feature. With
input from an echo sounder, the autopilot can be set to steer the
boat to a set depth. This is very useful if you want to follow a
depth contour.
Smooth seabed Rocky waters
Slope Narrow channel Ridge
Caution ! Do not use this feature unless the seabed is suitable. Do not use
it in rocky waters where the depth is varying significantly over
a small area.
Ensure that the depth-turn pattern has been selected under the
User Set-up menu. Refer to Turn Pattern select on page 55.
Make sure you have depth reading available in the system. Press
the TURN/DODGE button repeatedly until DEPTH is flashing
in the display. The actual depth reading is shown on the display.
