    Helix 12si and 999si

    I have a older helix 12 SI on my console and a 999 SI on my trolling motor. I want to swap locations so my question is are transducers the same or do I need to swap transducers as well?
    Thanks

    If that is the first Gen Helix 12 .... the transducers should be the same HS 9 HDSI 180 T.

    Thanks Bob. I was tempted to just swap them but I wasnt sure if I'd smoke something.
