Speed

The Fishfinder 100 Blue can display the boat’s ‘Speed’ Over Water when equipped with a speed sensor. When set to ‘Auto,’ the unit will automatically sense when a capable sensor is connected and display the boat’s speed.

To set the Speed display field:

1.Highlight the ‘Num’ tab on the Setup Menu.

2.Highlight the ‘Speed’ selection field and press ENTER.

3.Choose ‘Auto,’ ‘Show’ or ‘Hide,’ then press ENTER to accept the selection.

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 Fishfinder 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.
