sprinkus, do you locate valves with the rigid? the low range of freqs give you an advantage over others on GF and utilities, my dynatel affords me the same luxuries. did you get training? metrotech called me about their new tools, they give you lifetime training as a pitch.[/QUOTE] SR-20 is worthless for valve locating, locates everything else though. The "sonde" units in combination with the SR-20 work great for locating any kind of pipe that you can shove the thing down. Training was acceptable. Pretty easy unit to use although I'll reiterate, well, after that last Jaegermeister my wife handed me I don't remember what reiterate means! Best ask me when I'm store mober.
