Here's a test of my readership: I need an actual opinion.
I pretty much assumed I'd want a separate GPS device, since they're a nearly foolproof way of grabbing your location no matter where you are. I didn't want to use my phone's GPS because it eats the batteries, and I hope to keep my phone fresh in case it's applicable in an emergency.
But here's the thing: an "outdoors" GPS is extremely expensive, like hundreds of dollars. Since I only plan on using GPS as a last resort, when maps, compass, and my own pretty reliable sense of direction aren't enough, is a unit worth it? Or would my phone be enough for rare and brief GPS usage? (There's an incredibly thorough GPS app for my smartphone, which contains 1. downloadable topo maps that are readable without a cell connection and 2. a nav system that communicates directly with satellites and is also operable without a cell connection).
I don't plan on bushwhacking; I'm sticking to marked National Park trails that are shown on topo maps and described in guidebooks. I'd probably use a GPS only if I accidentally ended up off the trail. And as I mentioned, I have a pretty good intuitive sense of direction, and I not only know how to read a map, but I actually enjoy cross-referencing my location with a map like every few minutes or so, even when I know where I am. So what's the advantage of a separate GPS? And is it 400 bucks' worth of advantage? If you've got more wilderness navigation experience than I do, please weigh in!
