there are two first pictures of the OSTC2 TR shown on the Homepage: http://heinrichsweikamp.com/ostc2tr.html
The first pictures shows the OSTC in dive mode with the tank data displayed within the custom view area.
The second picture shows two connected sensors in surface mode, again in the (surface mode) costum view area.
This is for the Sport version so far. For the hwos Tech version, tank data integration (with nice / unique features...) will follow soon.
