Does everyone use action camera on their tours? I am contemplating on getting one but not yet sure how to use it (run continously, turn on in a particularly scenic spots or ..) and which one to choose. GoPro seems industry leader but I can't quite justify the cost given a limited use (and not yet sure footage would be worth it). Anyone has experience with mid-range priced camera like hawkeye firefly or Sjcam or Xiaomi Mijia? Or should I stick with cell-phone shots and videos and be done with it?
