You can usually reroute the sonar unit s power cable and transducer cable away from the wiring that is causing the interference VHF radio antenna cables radiate noise when transmitting so be certain to keep the sonar s wires away from it You may need to route the sonar unit s power cable directly to the battery to isolate 1t from other wiring on the boat If no noise displays on the sonar unit from electrical equipment then make certain everything except the sonar unit is turned off then start the engine Increase the RPM with the gearshift in neutral If noise appears on the display the problem could be one of three things spark plugs alternator or tachometer wiring Try using resistor spark plugs alternator filters or routing the sonar unit s power cable away from engine wiring Again routing the power cable directly to the battery helps eliminate noise problems Make certain to use the in line fuse supplied with the unit when wiring the power cable to the battery When no noise appears on the sonar unit after all of the above tests then the noise source is probably cavitation Many novices or persons with limited experience make hasty sonar installations which function perfectly in shallow water or when the boat is at rest In nearly all cases the cause of the malfunction will be the location and or angle of the transducer The face of the transducer must be placed in a location that has a smooth flow of water at all boat speeds R
