I posted this on cave chat.org but no replies: So I'm awaiting shipment of my DistoX2. I've never used one before. I am trying to figure out what the best tablet is to use with it. I am using Therion but I am new to that as well. I used to use Walls and before that On Station. I have zero experience with paperless cave surveying. I have never used Pocketopo or Topodroid which makes it hard to decide between windows or android. Topodroid seems to be set up well for use with Therion, but again I have no idea; I've never used an android device only iPhone and iPad. I see the new ipad pro has a stylus - are there cave survey/disto apps that run on iPad? A new windows surface pro3 tablet seems like a good idea but are there good waterproof cases? Xperia Z4 tablet claims IP68 - can it handle a cave without a case? I can't seem to find any suitable rugged cases for it. If price was not a factor what set up would you use? Thanks
