Contour Lines (Optional-Purchase Lakemaster® Charts Only); Depth Colors (Optional-Purchase Lakemaster® Charts Only); Depth Highlight (Optional-Purchase Lakemaster® Charts Only); Depth Highlight Range (+/-) (Optional-Purchase Lakemaster® Charts Only) - Humminbird 1158c Combo Installation And Operation Manual

Contour Lines sets whether the water contour lines are visible or hidden in the Chart Views.
Contour Lines are also affected by the Water Level Offset setting.
Depth Color sets the depth shading in the Chart views to Off or Shaded.
Depth Highlight allows you to highlight a depth setting in the chart views. The depth you set
will be highlighted in green. Use Depth Highlight with Depth Highlight Range.
Depth Highlight Range adjusts the range on each side of the highlighted depth, when a Depth
Highlight is active in the chart views.
For example, if you know a certain fish is holding at 18 - 20 feet, you can set the Depth Highlight
at 19 feet, and the Depth Highlight Range a +/- 1 foot. The view will show a green band from
18 - 20 feet.
Water Level Offset allows you to change the level of the water being read from the control
head. The displayed numbers on the Contour Lines will adjust from the Water Level Offset
setting, and the water level offset will be highlighted in dark brown.
For example, if the lake is down 5 feet, set the Water Level Offset setting to -5.
