I just ordered a GC2 with no software. What do I need to run TGC? I'm being told by a supplier that I need the ProTee 2.0 software and then there is some sort of surcharge???? TGC is available at swingsense for 795 , and Protee 2.0 with TGC is 1595. If you have this running on yours with no foresight software could you please offer your knowledge. Thanks
