Thanks for the feedback. I really dont want an external. Im actually considering the 385 portabke with the soft pack. I dont always need gps but its nice to have to mark spots. Dont mind spendin a little more to have it. Just want to make sure it keeps a signal most time unlike my 522. Itll be sittin in a jon boat in its soft pack. Most likely be sittin on the bottom of the boat. Geez, how clear of a view do these things need lol?
