PocketTopo is the software part of the paperless cave surveying package developed by Beat Heeb. It runs on Windows devices (pda and desktop) and is best used in conjunction with a modified Leica Disto X310 (making it a DistoX2 to cavers). PocketTopo is free, but you must buy your own disto, upgrade kit and computing device. It plays nicely with Therion.
Although it runs on Windows 10 just fine, you may like to set up a Windows XP virtual machine to facilitate a direct connection with the pda data collector used in the cave.
