I just moved to Chesapeake and thought it prudent to use a GPS
. My old boat has a Standard Horizon plotter, but it appears that it needs a C-Map
chip to operate. I have just spent two hours trying to figure out exactly what I need and am amazed at: a) how vague the info on these charts
are and b) how expensive they seem to be.
I just bought the Navionics
for my Droid for less than $20. It appears the C-Map charts
will cost several hundred.
What's so special about C-Map? Is there one chart to buy or do I need several?
