    Default Finding USTs with EMI?

    I do private locating, and environmental companies always ask me to find USTs. I I've tried several times to locate edges of USTs by connecting to a vent pipe - with no success - seems to light up everything in parking lot, especially if there's rebar involved. First of all, is it possible to find edges (within 2-ft) of USTs using EMI; and second, How???

    Backhoes find everything. I can only think of Ground Probing Radar. These days some tanks are made of fiberglass or other nonconducting material. Plus modern transmitters are making higher wattage outputs, one does not want a spark in a storage tank that had or has flammable liquids.

    Hi WNC, I do a lot of UST locating, what I find most helpful is a split box detector and a magnetometer. I prefer the aquatronic a6 and schonstedt ga92tx. With these two tools you can find lots of tanks as long as they aren't or more feet down. The a6 is great at outlining the fact that there is something and can be used to outline it and get a rough estimate of the size, the magnetometer is good for a closer pinpointing of the edges based on the polarity change for a solid steel object. rebar will mess this up though, and it will only find steel tanks

    Ditto.... Split box is a miracle worker in the right hands.
