Possible causes Possible solutions
Sonar disabled Enable [Ping] from the Fishfinder app's sounder tab:
[Menu > Settings > Sounder > Ping enable].
Incorrect transducer Check that the correct transducer is selected in the
selected Fishfinder app's Transducer tab: [Menu > Settings
> Transducer].
Damaged cables 1. Check that the transducer cable connector is
fully inserted and locked in position.
2. Check the power supply cable and connectors
for signs of damage or corrosion, replace if
necessary.
3. With the unit turned on, try flexing the cable
near to the display connector to see if this
causes the unit to re-boot/lose power, replace
if necessary.
4. 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.
5. 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.
Damaged or fouled Check transducer condition, ensuring it is not
transducer 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.
Wrong transducer Check product and transducer documentation and
fitted ensure that the transducer is compatible with your
system.

Possible causes Possible solutions
External sonar Check that the unit is correctly connected to your
module: network display or network switch. Check all connections to
connection problem. ensure that they are secure, clean and free from
corrosion, replace if necessary.

may prevent
communication.
No depth reading / lost bottom lock
Possible causes Possible solutions
Transducer location Check that the transducer has been installed in
accordance with the instructions provided with the
transducer.
Transducer angle If the transducer angle is too great the beam can
miss the bottom, adjust transducer angle and
recheck.
Transducer
If the transducer has a kick-up mechanism, check
kicked-up that it has not kicked up due to hitting an object.
Power source With the product under load, using a multi-meter,
insufficient check the power supply voltage as close to the unit
as possible to establish actual voltage when the
current is flowing. (Check your product's Technical
specification for power supply requirements.)
Damaged or fouled Check transducer condition, ensuring it is not
transducer 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.
