Navionics does not offar a global set of charts. That being said with a newer chart plotter you can buy the Chart Plotter with out charts (saving money) and add Gold charts, they are updateable from the
internet. One thing with updates is that you need a good
internet access. So if you ae going to an area that is not going to have good internet update the charts before you leave for that area. The Navionics Gold charts can be used on a PC or Mac with the
Fugawi PC programs. And yes Navionics does have charts for your
iPad. If you want to see the charts before you
purchase them you can go to the Navionics web site and click under products and then webb app. it is their veiwer. No coverage of
Canada or
Denmark (Gov. issues)
