[QUOTE=Roger C;3887373]Are you saying that Helix G2 units can now use a y cable and transducer switch for 2 transducers? I was told by HB that you could not do that with chirp. Or am i not understanding your y cable comment?

Roy is not using a transducer "switch" .... it depends on what 2 transducers you are talking about.

This is the same type of setup HB has always used so a seperate 2D transducer can be used to obtain better high speed 2D readings than can be obtained from the SI transducer. The 2D always comes from the 2D transducer that has the Y cable connected to it. It can be a skimmer on the transom or a shoot thru type 2D transducer.

The only difference here is that the recent software update for the MSI G2N now allows a setting to utilize a Low Q 2D transducer which previously only worked on the G3N units.
