I sense youre trying to keep it mounted low so as to have sonar with the 797 while on plane. Im afraid that may just not be that that feasible with the current state of designs with these huge transducers. But thats just the sacrifice for having the side imaging. However since the side imaging wont make sense at high speed anyway, mounting it higher doesnt seem to me to be that big of a deal. And you can just use the in-dash flasher for the high speed reads, which is what its there for anyway.Just my thoughts, but I could be mis-reading your situation.Deke[font="]Deke[/font]
