electrical wiring on the boat may help.   
2)It also might because the transducer cable is broken or pinched. 
3)Check the connectors to make sure it is securely plugged into the unit. 

 

7. Weak Bottom Echo, Unstable Depth Reading, or No Fish Signals. 

1) Make certain the sonar sensor is pointing straight down.   
2) Extremely heavy vegetation may confuse the sonar signal, causing it to misinterpret the 
depth. If you are certain that the readings are incorrect under these conditions, discontinue 
use. 
3) Oil, dirt and fuel might cause a film to form on the transducer and reduce its effectiveness. 
Cleaning the face of the sensor might help. 
4) Electrical noise from the boat's motor, trolling motor, or an accessory interferes with the 
sonar unit. Rerouting the transducer cables away from other electrical wiring on the boat 
may help.

 

5) Please check the battery voltage. The unit's transmitter power will decrease due to the 
voltage drop. And this will reduce its ability to find the bottom or targets. 
6) Please check the Sensitivity settings. Choosing High Sensitivity might help. 
7) The sonar might be in turbulent water. Mounting it in a smooth flow of water might help. 
8) The reason might be that the boat speeds over 5 mph (8 kph). Slowing the boat down might help.
