uses a small SD card and reader that works great with my PC. I buy one SD (chip) and it will plug
into my plotter in the cockpit
or my PC down below...thus I have two systems running at all times.
I used to think it was required to have two discs (SD cards), one for my PC and one for the plotter until I found out you can fire it up in your PC, then pull the chip out and put it in the plotter...when I asked, Navionics
replied that was how they designed it. So, I use a Navionics USA West series chart (in this case #12)... along with a Progin GPS
that that I got from Ebay... hooks directly to my PC and I basically end up with two operational systems. I can do my trip planning and data package stuff on my PC and nav tracking in the cockpit
. Anytime we need to do some waypoint or tack work we use the PC...to sail along we use the plotter...each is a double check for the other.
Cost of the card reader? Mine was free (yeah right
) with my purchase
charts. Not sure about their outright costs... might have to ask Navionics. The SD Cards (I call them chips because the are so small) cost about $199 each...West (SD12XG) covers USA west coast
down to and including Mexico
and I think part of Central America
. So far they've been spot-on as ENC's.
BTW ...I have no affiliation with Fugawi
, or Navionics...just somebody out here using their products. Usual disclaimers apply.
