My boat has a C-80 display installed by the previous owner. The boat has a pathfinder radar, GPS, Auto Pilot an ST-60 digital depth readout. All read through the C-80 with the exception of depth indicated by the st-60 display, and the auto-helm control. I do know the auto helm is also connected to the C-80 display. All work efficiently at this time. My question: I want to add a fish finder, and it appears the C-80 is capable of that function from the literature I have. What do I need to add to connect the unit to read in a fish finder mode on the C-80 in addition to the digital depth on the ST-60. Do I need to add a DSM? Do I need a new transducer as well, or can the existing transducer run both? The books left aboard indicate the depth sounder is an A22020. The C-80 display is E02020.
