I have a 797c SI unit
I also have a plain old 525 unit, the site says the transducer is the XNT 9 20 T
I don't have a lot of battery juice so I wan to cut down power usage. I think one way to do this is to use the 525's transducer.
Can I do this?
If I have both units hooked up with a y cable can I use the interface to turn off one of the transducers?
