At the top left of the display you will find the Adjustment Bar and a variety of user-selectable information including Depth, Battery Voltage, Water Temperature, and Speed Over Water. To provide data on Water Temperature and Speed Over Water, the Fishfinder 100 requires a transducer capable of producing the particular data.

The Depth Scale and the Flasher Function are displayed from top to bottom along the right side of the display. Messages and Alarm Icons are displayed along the bottom.

The Fishfinder 100 has three levels of display backlighting, Off, Low and High. The backlight is activated by momentarily pressing the Power key. To change the backlight level, press the Power key repeatedly.

If the unit is unable to track the bottom for any reason, the digits in the depth window will flash on and off to alert the user that the unit is not tracking the bottom.
