Sounder/plotter for PWS and interior rivers

[cabin goer]

I have a inboard jet boat and use a Montana 600 with the G2 Charts on it for shrimping with the help of $100 depth finder that came in my boat (that works when it feels like it) I looking for what is the right setup for a guy that spends 6 days a year in the salt and the rest on the big su.

I would like to be able to see bait balls and rock piles ect.
