Took care of my problem.
I had an older Precison-Pro that my kids had given me for Father Day a few years back and it had quit working. They helped me diagnose that after years of being dropped, jettisoned from badly driven golf carts played on non-pristene golf courses, and generally abused, it had died a grizzly death. They graciously offered me a 30% discount to upgrade. I realize that they will do a trade in for any of us hacks, but the fact that they answered several emails from me, and helped me to come to the sad conclusion of the devices demise, I thank them and appreciate their diligence.
