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.
