Possible causes
Transducer location
Transducer kicked-up
Damaged or fouled transducer
Damaged transducer cable
Turbulence around the transducer
at higher speeds may affect
transducer performance
Interference from another
transducer
Unit power supply fault

Possible solutions
• Check that the transducer has been installed in accordance
with the instructions provided with the transducer.
• If a transom mount transducer is mounted too high on
the transom it may be lifting out of the water, check that
the transducer face is fully submerged when planing and
turning.
If the transducer has a kick-up mechanism, check that it has
not kicked up due to hitting an object.
Check the condition of the transducer ensuring it is not
damaged and is free from debris / fouling.
Check that the transducer cable and connection is free from
damage and that the connections are secure and free from
corrosion.
Slow vessel speed and recheck.
1. Turn off the transducer causing the interference.
2. Reposition the transducers so they are farther apart.
Check the voltage from the power supply, if this is too low it
can affect the transmitting power of the unit.
