title_body: Is there a way to override the distance limit on a DJI Mavic Mini without a mobile phone app?
upvoted_answer: Currently no, barring exploiting vulnerabilities on the platform (which DJI are pretty quick at fixing) there is no way around the distance limit. The wide field really won't be your issue here. At 60m you can't see it safely line of sight.
  
  Why not get a cheap phone just for this purpose? Doesn't need to be fully featured, or indeed that current - just check compatibility with DJI first.
