Brian: I think you made the right call for now. Chuck's DT Systems is a wonderful unit, and I think it was designed around Hickox' system which is about the best out there for a step-by-step program. You may not need or get full use out of all all the buttons until you spend some time working that system. The collar makers have all come a long way since your collar was built but yours is fine for now. Welcome home and thank you for your service.
