Depth Number

The 'Depth Number' setting refers to how the unit finds the digital
depth number that is displayed in the upper left corner of the screen.
When set to 'Auto,' the unit will show the most accurate digital depth
possible. However, this may cause the chart to update slower as the unit
calculates the 'Auto' depth. When set to 'From Chart' (default), the unit
finds the digital depth from the same image you see on the chart. The 'From
Chart' setting allows the chart to update faster than when the unit is set to
'Auto' and is recommended when using the unit in deep water.

NOTE: In 'From Chart' mode, the Fishfi nder 100 Blue may
not be able to get the digital Depth Number if the bottom
is not visible on the chart. Adjust the Depth Range on the
Adjustment Bar until the bottom is visible, or change the
setting to 'Auto' to get the digital Depth Number.
