If there are any nautical charts (C-MAP, Navionics) compatible with the Furuno TZ Touch2 and have high-resolution Bathymetry (for fishing), please let me know. I sincerely appreciate it.
Chart availability is very area dependent. Many areas have high rez fishing bathy available to licence from C-map. Please contact your local Furuno tech support with an exact lat/lon and they can provide options and some screen captures.
