New to using GPS. Just bought a Garmin 62S along with Garmin Upper Midwest Anglers Guide SD chip. The chip is enabled and the menu is set on fishing. Do you have to be on the actual body of water such as Lake Winnebago before you can view any detail such as bottom contour, reefs, etc. etc.? Or, is there a way to view that lake in detail without being on the body of water itself? Thanks for any input.
