everything has been put through furuno. Initially I was told that I had problems with the Cutter Gain and TVG settings. Thanks to you, I found out the interference due to missing the earth wire. If I put the transducers in line, I must modify the engine's water intake or put it to the starboard side. I am thinking of putting both transducers in a single hand-made transducer. What do you think where I think I should put the transducer? in the future I think I want to add the Di-FFAMP box with a 2 / 3kw transducer and I was planning to put on the starboard side so for now I only want to use one side
