I haven't tried the Active Captain app - I'll look into it, thank you for that prompt. It does show pre-purchased maps, but the Canada Lakeview 2016 which came with my 95sv is in 15 or 30ft increments for the lakes around me and low accuracy at that. Homeport shows my waypoints and tracks, but doesn't show my quickdraw contours, which is what I'm really after. (I realize that when I then turnaround and use Facebook I'm a big hypocrite, but it doesn't change how I feel.)
Beyond that, I simply can't get over the fact that I'm paying Garmin over $1000 for the privilege to spend my time and gas to make something that directly benefits them.
So if I do 3-4 trips to a lake over a summer, then upload, I'm not providing much in terms of mapping, but I'm giving a very clear map of where I fish. It would take 1000s of hours to map just one of our big lakes (sounds like the panoptix 'ducers make it go much quicker, and will be one more reason to get the upgrade for me).
Up here we have many large lakes and very few people. AlgaeKilla, you're right, I could choose to take a generous approach to it, to a great extent my outlook is specific to my location.
