Fish finder

[fonduvfishin]

I have a two finder setup: 1 ducer mounted to the stern for the console unit and the bow mount has the ducer built into the trolling motor. I have not experienced any interference between the two units, but this may be due to the fact that each cone originates from its source and the sources are 20 feet from each other? In addition, the bow mount unit has six ceramic transmitters that each receive their own echo back to the unit and combine the six signals into a 3 dimensional display. It might be possible to "T" the transducer cable to units, not sure if that would decrease the signal strength though?
