I have the gold card in a humminbird combo. 597ci hd di.
The maps do not extend past about three miles offshore(East coast Florida). And when I am fishing Flamingo, I lose all maps when I get above shark river area or West of Cape Sable.
Any help would be appreciated.
I also show very little contour and there is no depth marked on the screen.
Will an upgrade to navionics + help with these issues?
