When upgrading to Solix mega from Onix it seems to me that everyone doing so would end up with a Onix side imaging transducer that is of no use to them. The transducer is pretty expensive from what I see and no longer being manufactured. I am not currently ready to upgrade to Solix but am having an issue with my 2014 Onix SI transducer ( one side going dark ). I don't see anything in the swap and sell so just wondering what everyone is doing with them and why?
