Hey guys sorry for the dumb question I have fished my entire life and only used a fish finder for depth reading. I have jumped on board and upgraded electronics to Garmin 126sv for livescope and a garmin 93sv for mapping (for now until I goto Hummingbird for mapping—- money constraints after buying all new electronics I’m sure some
of you can relate lol).

what card do I need for the maps to see the countours and channels etc? I don’t think it’s navionics , I just want to make sure I get the right card imma bit confused on which card? I fish mostly Louisiana and Mississippi, so southern lakes I’m assuming.

any help would be greatly appreciated! Thanks
