Hi guys, need some help from you tech savy folks. I have a lowrance lms 522 c, fish mostly inland rivers, some lakes, and coastal inshore rivers. I m looking a map card that will fit my kinda of fishing.
I have looked at hotmaps, which says it covers lakes, and there is navionics that covers coastal and the big water (ocean)
Does anyone know of a card that will work with lowrance, covers North Carolina, and has detail of inland rivers as well as coastal rivers.
I will greatly appreciate any advice yall can throw my way.
Thanks alot
