Navionics on an iPad - Beware
This is an awesome piece of kit which knocks the spots off any small to medium sized chartplotter.
I used it happily up and down the coast and was impressed with how it managed to track me when I was out of mobile coverage. I decided that it would be very suitable to use on long journeys for emergencies.
When I was up in the Hebrides, however, I found that the GPS does not work at all when in an area with definately no mobile coverage. I am not sure that I would feel reassured when out at sea, out of sight of land, or with low cloud, and not being able to use the iPad to work out where I was.
So for all of you that wish to buy the fab £15 app instead of a chart plotter, just beware!
