Just curious, because I just tried it for rough planning a potential coasthop from Michigan City, IN to Mackinac City, and it seems like while it's a bit clunky, and not really suitable for navigation
, it'd help in a pinch.
Among other things, coasthopping in Lake Michigan, chances are good you'll have net access with even a 3G or 4G Aircard or smartphone or tablet. Since you can plot your position even with handheld GPS
or using a sunsight or starsight set with a sextant
for your coordinates, and enter those numbers and get a far larger display than your tiny handheld's screen
on your laptop
or tablet or a backup to paper using your iPhone
or Android device.
You can also run a line plot using the recording function to see a broad trend, at least. Just use the straight line function and save, and you can go back and edit to add further line plot. It wouldn't be my first option, but I'm just trying to think of alternative solutions for a FUBAR occurring of some sort. I realize I may well be reinventing the wheel
, here, I'm actually more interested in if my thinking is at least valid for limited or emergency
