Interference on Furuno FCV 587

[Anonymous]

Hey guys

anyone know what the deal is with the interference towards the top of the image and how to fix it?

the following pic is taken with engine off and no movement. Always getting constant interference.



Transducer is definitely below the bottom of the transom as far as i can tell...





any ideas?

Adamsanta,
First turn off the BD mode in that shallow of water. Also know that using a TM series that most of the TX power is going down but actually some also goes up. My feeling is if you put your hand over the top of the transducer you will see that band change. Also there is a control called Zero Line that can be adjusted.
