Finding the Cause of Noise

Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause noise or interference:

Possible Source of Noise

Isolation

Other electronic devices

Turn off any nearby electronic devices to see if the problem

 

goes away, then turn them on one at a time to see if the

 

noise re-appears.

The boat’s engine

To determine whether the boat’s engine is the source of the

 

noise, increase the RPMs while the boat is in neutral and

 

stationary to see if the noise increases proportionately; if

 

noise appears when you rev the engine, the problem could

 

be the spark plugs, alternator, or tachometer wiring. Replace

 

the spark plugs with resistor plugs, install an alternator filter,

 

or route the control head power and transducer cables away

 

from the engine wiring.

Cavitation from the boat’s

Turbulence created by the propeller can cause noise; make

propeller

sure the transducer is mounted at least 15” (38 cm) from the

 

propeller, and that the water flows smoothly over the face of

 

the transducer at all times.
