Adjust the Water Level Offset
When you start your mapping for the day, it is important to note if the water level is higher or lower than usual. For example, if you
are mapping on a lake and know the lake is down 3 feet, set the Water Level Offset to -3.
1. Main Menu: Press the MENU key twice. Select the HB Chart tab.
2. Select Water Level Offset.
3. Use the RIGHT or LEFT Cursor keys to adjust the setting.
If the water level is higher than normal, set a positive amount.
If the water level is lower than normal, set a negative amount.
If the water level has not changed (normal), turn off Water Level Offset.
