Lets Talk Electronic Charts

[Randyonr3]

So I'm setting around the club bar when someone pulls out his "I-pad" showing the route he did on the ditch run.... surprising the charting was really clear and spot on for detail..
In chatting with him, its a Navionics program...
so for the last few years I've been using a Ray Marine plotter with C-Map chips at a cost of about 250 each.. and I now see the same areas and avalable to purchase at 6 dollars per section..
so its simple math... C-map for 250 for Hawaii or a 6 dollar addition to a 45 dollar program thro Navionics on an Ipad......
So something else has come now..........................
In checking the different pads avalable at "Best Buy" I'm told the windows version does not support the same Navionics programing that the ipad does..
can someone shead some light on these subjects.......
Whats avalable, and do the newer windows based unit support the programs............
