Old paper maps still win when the sky goes out of range, but they’re just a backup now. A GPS that fails is a GPS that’s gone wrong, while a paper map is a silent witness you can still read. Use both: paper for the “if‑we‑get‑lost” case, GPS for the “if I’m not going to get lost” case. And don’t forget the compass—you never know when the cloud will swallow the screen.
