Help us, that current Irish Chart is horrendous. Should nearly be outsourced to the CAA who produce lovely charts lol
That said, I use the chart and SkyDemon in a traditional way. I plot a route from waypoint to waypoint which I also draw out on the chart with a printed plog from SkyDemon.
I could go direct but wypt to wypt usually only adds a couple of miles and it gives me a paper backup for the navigation process.
I run SD on a 7" tablet, with a bluetooth gps dongle (to load-balance the battery usage). I have a large battery bank with enough capacity to charge the table, dongle, phone (with SD) with power to spare
And I still have my ole Garmin 96 to hand chugging away in the corner
