Water Level Offset (Optional-Purchase Lakemaster® Charts Only); Shallow Water Highlight (Optional-Purchase Lakemaster® Charts Only); Lake List (Optional-Purchase Lakemaster® Charts Only) - Humminbird 398ci SI Combo Operation Manual

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.
Shallow Water Highlight allows you to select a minimum shallow depth
setting so that the depth is highlighted in red in the Chart Views.
For example, if your boat has a draft of 3 feet, set the Shallow Water
Highlight feature to 3 feet, and the unit will draw a red band from 0 to 3 feet.
Use this setting with Water Level Offset.
Lake List allows you to view the list of lakes included on the installed
SD memory card.
Sort By: Highlight Sort By, and press the RIGHT or LEFT Cursor keys to
