This is an add-on system for the Shuttle Box system (Core). The add-on system will upgrade your core shuttle box system with everything needed to run an additional shuttle tank from inside ShuttleSoft 3.
Note that ShuttleSoft 3 can run up to three shuttle tanks from a single PC. If you want to run three shuttle tanks, simply add 2 x Shuttle Box system (Add-on) to your Shuttle Box system (Core).
For Witrox users
ShuttleSoft 3 is fully compatible with our Witrox 1 or Witrox 4 oxygen instruments and can be combined with the WTW instruments.
