Charts?

[Redders]

Hi!
Just picked up a used Lowrance Hook 9 Triple Shot. Looking for some options to get a chart on there for local fishing if anyone has any ideas? Has Navionics preloaded but isn't showing depth contours and there's no card. Is it possible to buy the govt maps individually anywhere?

you can get the c-map countour+ if you want depth contours.
