Location: Madison, WI | Quick question if you dont mine....if you purchase a Navionics +, it only has the nautical charts preloaded on it. If you want all the Sonar Chart data (with 1ft contours), you have to update the chip online to put all that information on the card?
It appears that LOTW is not 1ft contours (on the nautical charts) as when i put that into my HDS 9 thats what I get, but when you click on Sonar Charts on the Webapp, 1 ft contours show up.
Im assuming that I have to update the chip online to add all the "Sonar Chart" data to the maps and then the 1' contours will show up? Does this sound correct or am I missing something. |
