Testing the Installation

While it is possible to perform some checks with the boat trailered, the boat should be in the water to properly test the installation.

Press the Power button and the Fishfinder 100 Blue should power on. If the unit fails to power on, verify that the wiring adapter is seated properly in the back of the unit, the Red and Black wires are connected to the correct polarity, and the 2-Amp fuse is installed and not blown. If the unit is connected to a power supply that exceeds 18 VDC, a ‘Battery Voltage High’ warning will be displayed and the unit will turn off.

As the unit powers on, it should immediately start showing the bottom. Verify that the unit is not in the simulator mode. If the unit is in the simulator mode, make sure that the transducer is connected to the wiring harness.

To test the transducer and speed sensor installation, gradually increase the boat’s speed while checking the unit operation. If the unit displays intermittently or fails to display, verify that the transducer and speed sensor are aligned parallel with the bottom. If necessary, adjust their heights until the unit operates correctly. It may be necessary to make several adjustments to ensure proper operation throughout the speed range. If the signals do not improve, it may be necessary to move the transducer or speed sensor to a different location.

When adjusting the depth of the transducer, make the adjustments in small increments, no more than 1/8”. Placing the transducer or speed sensor too deep can adversely affect the boat’s performance and increase the risk that they may strike underwater objects.

Simulator Message and Icon

If the Fishfinder 100 Blue is in Simulator Mode, the message “Simulator On” will be displayed along the bottom of the screen. The message will be replaced by the “S” icon indicating that the unit is running in simulator mode.
