I was thinking I'd get a good electronic GPS in addition to having my smart phone and get some APP for directions, and carry a map as well.
Your smart phone might have a built-in GPS chip, this is something you can look up online with a little sleuthing. There are some decent apps that make a smartphone work essentially like a GPS, with some caveats.
First, battery power; with a standalone GPS, you can carry extra (typically AA) batteries; Lithiums are very light and work best in cold weather as well.
Second, with any GPS, I think that any person really needs to do a fair bit of practice, at/near home and/or on trips to places already pretty well known. This is not something you can count on just figuring out on the fly when you need it. There are a lot of options, the user interface is often not very intuitive, it takes time to get comfortable and good at the subset of features you'll tend to use.
Whatever sort of GPS you opt for, I strongly suggest that you use the GPS to build up your "don't need the GPS" map skills. I.e., on wilderness trips keep pulling out your map and try to associate where you are (just be looking around plus sort of keeping track) with where you think you are on the map. Then
after doing that, pull out your GPS and see where you actually are. Wash, rinse, repeat. I think that's a really effective way to get map reading experience in a practical way.
I don't mean to sound patronizing or preachy here, it just seems that it's a natural human tendency to load up on "the right gear" and assume that just sort of having it with you is sufficient preparation!
