If you can handle digital navigation, you will never go back to a paper map. However, there are some downsides I have to cope. Firstly the limited accumulator power, easy to solver with a power bank, or second phone. More serious is a rainy day, my waterproof smartphone couldn’t stand raindrops following on the screen and got crazy. The watertight case was unsuitable either hard to deal with or fogged up. A simple homemade device is currently the solution. The overall advantage, I get every information I need, offline or online, on a fingertip.
