Possible causes Possible solutions
Targets will appear
differently if your vessel
is stationary (e.g.: fish will
appear on the display as
straight lines). Increase vessel speed.
Scrolling paused or speed
set too low Unpause or increase sonar scrolling speed.
Sensitivity settings may
be inappropriate for
present conditions. Check and adjust sensitivity settings or perform
a Sonar reset.
Damaged cables
1. Check the unit’s connector for broken or
bent pins.
2. Check that the cable connector is fully
inserted into the unit and that the locking
collar is in the locked position.
3. Check the cable and connectors for
signs of damage or corrosion, replace if
necessary.
4. With the unit turned on, try flexing the
power cable near to the display connector
to see if this causes the unit to re-boot/lose
power, replace if necessary.
5. Check the vessel’s battery voltage, the
condition of the battery terminals and
power supply cables, ensuring connections
are secure, clean and free from corrosion,
replace if necessary.
6. With the product under load, using a
multi-meter, check for high voltage drop
across all connectors/fuses etc (this can
cause the Fishfinder applications to stop
scrolling or the unit to reset/turn off),
replace if necessary.
Possible causes Possible solutions
Transducer location • 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.
Transducer kicked-up If the transducer has a kick-up mechanism,
check that it has not kicked up due to hitting
an object.
Damaged or fouled
transducer Check transducer condition, ensuring it is not
damaged and is free from debris/fouling. If
necessary, clean or replace your transducer.
After cleaning or replacement coat the
transducer using a water-based anti-fouling
paint.
Damaged transducer
cable Check that the transducer cable and
connection is free from damage and that
the connections are secure and free from
corrosion.
Turbulence around the
transducer at higher
speeds may affect
transducer performance Slow vessel speed and recheck.
Interference from another
transducer 1. Turn off the transducer causing the
interference.
2. Reposition the transducers so they are
farther apart.
Unit power supply fault Check the voltage from the power supply, if
this is too low it can affect the transmitting
power of the unit.
