When going out scalloping the other day I prepared for navigation
on my trip by making sure that I had the correct section of the Navionics
chart downloaded to my iPad
(I zoomed out and saw that the area I wanted to go was colored white which meant that the chart is downloaded for off-line use).
But when I got out on the river I realized that I didn't have any contour lines in the river on my chart!
I realized that I had not UPDATED the chart. It was downloaded but not UPDATED.
So in the app I went to menu->update all and downloaded the latest updates. Voila! My contour lines showed up.
Next time I'll make sure to update my chart before I leave so I don't use my cell data to download the data.
Live and learn.
Just figured I'd share what I learned this week.
What have you learned that would help other boaters?
