I can tell you're no stranger to modern technology. Personally I find that its ok to do this with the charts from the Small Craft Folios but the full size Admiralty jobs are too thick once folded. A bit like me really!
For full size Admiralty jobs you use the sliding tray they provide, but you must be sure to insert it the right way up. Could you imagine how silly it would look if you put them in upside down.
Only bought mine at the show because it looked so very easy to use. I thought all I needed to do was plug it in! Then I found it needed to be wired up! Still it makes a good chart table.
