I've had good results from Lowrance on my PB and kayaks, your application, top end, I would be looking at the Elite FS 9" Active Imaging 3-in-1, but if you wanted to ease back on the spending, the Hook Reveal Tripleshot 9" at $599 would get the job done. I have had a Hook2 5" Tripleshot on my kayak since 2018, excellent estuary/river inland and near reef OFF-shore.
