I just purchased a hummingbird helix 7 and am looking for recommendations for maps. I spend 90% of my time on upper lake Marion and Congaree river. Has anyone had any experience for mapping info in this area? I can use google earth but would really like satellite imaging on my chart plotter. The hummingbird basemaps have no info on sparkleberry or other stretches outside of the main river.
Any tips are greatly appreciated.
