The ‘Tools’ tab contains the ‘Flasher,’ ‘Simulator’ and ‘Noise Reject’ 

tools. The ‘Noise Reject’ and ‘Flasher’ tools are used to enhance the chart 
and help in identifying and providing information about an underwater 
return.  The ‘Simulator’ tool is used to enhance the simulator mode by 
allowing you to customize the simulated transducer selection. To access the 
‘Tools’ tab, place the highlight over it using the arrow keys. 

With the ‘Flasher’ tool active, a graphic Flasher representation will be 

displayed on the far right side of the chart.  This graphic Flasher displays 
structure and bottom returns much the same as a true Flasher.  You may 
find this feature particularly useful when using ‘Fish Symbols.’

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

2. Highlight the ‘Flasher’ selection fi eld and press ENTER.

3. Select ‘On’ or ‘Off’ and press ENTER to accept the selection.

The ‘Simulator’ tool allows you to select a simulated transducer type for 

use with the Fishfinder 100 Blue’s built-in display simulator.  These choices 
allow the simulator to more accurately depict actual operation of the unit.  
For details on using the simulator, see page 35.

The ‘Noise Reject’ tool helps filter unwanted noise from the chart.  The 

‘Noise Reject’ tool can be turned ‘Off,’ set for ‘Auto’ (automatic) adjustment 
or set for ‘Manual’ adjustment.

Remember when setting the Noise Reject tool, the 
higher the noise rejection setting, the more likely 
the unit is to not show fi sh or structure.
