998c SI
« on: March 08, 2014, 08:42:41 PM »
The zero line at the top is at 2 feet. I tried Depth Offset that moves it to zero but subtracts it from the depth reading making
the depth reading in error. Is there a zero adjustment some place,that will move the entire display to zero it  and keep the correct dept reading. It always has had this problem. The unit is 4 years old.

Press the menu key once to go to the Sonar Express Menu and check what the Upper Range is set to. If it's other than zero, change it to zero.

By using this feature you can eliminate surface clutter, etc., or look from a specific depth to the bottom, by changing the setting to 10 feet or whatever.

Whatever this is set to is the depth point where the graph begins to display.
