Is it possible to run two tansducers from one fish finder. One at a time ..example, one connected to the transom then another on a pull behind towfish. My thought is to use the transom mount tranducer to spot something of interest then swing around with the towfish to get a closer more detailed look. I know I could plug and unplug the wires, but is there a switch that could be used to change from one to the other. I saw the switches on on the site but says they are for using one transducer to change between two fish finders.
