i got a call around 0700 yesterday from a guy that always sits next o me at seminars, great guy, good troubleshooter. they had a Cal Trans job that had an open on the install, head guy spent 2 days with a 521 tracing wires and couldn't find the compromise. i was to call the head tech/foreman when i passed a certain bridge and he would get me into a turnout. i call, turn around and pull up and the guy tells me that he found the faulty splice just before i called him. this guy is grinning ear to ear and looking at me funny, at the verge of laughter. come to find out his boss told him that if he couldn't find it, that he would call someone that could. i don't know if he was grinning because of the way i look or that he may have saved his job. i demoed the pro-800, showed the kid how to do a short to earth measurement (which would have saved his ass in the first place) and pinpointed 2 solenoids in wireless mode. all in all, they got their moneys worth. i have as of now located 20 valves in wireless mode, tomorrow i hope will be 28 as i have a locate 50 miles south with a common compromise and 8 missing valves. i have asked a few of the 800 owners to attempt a wireless valve locate and so far no one has had, i don't think that what i am doing is anything special and i am not ready to say that all valves can be located this way but, i'll give it a try tomorrow.
