I retired and live in Venice Italy. I’m trying to find something like this that will give me the following: I need a map of the Venetian lagoon loaded with internal gps to find my way around the lagoon, also a fishfinder with transducer for both salt water and fresh water. Can this do all this for me? 7 inch screen? What else do I need to purchase?
Steven Mark says
You Can Use it for salt and fresh water both, But I’m concerned it’s maybe not Venetian Map preloaded.
