Contour Lines
(optional-purchase LakeMaster® charts only)
Settings: Hidden, Visible; Default = Visible
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 Colors
(optional-purchase LakeMaster® charts only)
Settings: Off, 1-10; Default = Off
Depth Color sets the depth shading in the Chart views to Off or Shaded.
Depth Highlight
(optional-purchase LakeMaster® charts only)
Settings: Off, 1 - 180 feet, 1 - 30 fathoms, 1 - 60
meters (International Models only); Default = Off
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.
