I have a HDS 8 up front and a HDS10 on the console do not have downscan up front just a 2D transducer,is it possible to have the front unit use the LSS2 from console unit and have down scan and 2D show up front I know it will be reading from the back of the boat but at least I will be seeing the same side by side pics instead of using it now and it shows the 2D up front but the down scan is 18 behind what I just saw on 2D?? hope I explained this right
