Don't post much...but I sure like this group of Aldeer. I work for a company who locates pipe, among other things.... that is considered an unlocateable pipe with no tracer wire or tracer tape. For those who may not know...you need tracer wire or tracer tape that is supposed to be laid with the pipe when put in the ground with companies who transport gas, water, etc. Today out in West Texas I put this beast of a locator on the ground that does not have soil restrictions...and located their pipe no hook-up or insertion. Hookup or insertion energizes the line for a traditional locator to locate the pipe and very common in practice. When there is no hook or ability to energize the line it makes things very difficult and costly. Amazing results...located a 12" Poly and a 2" Cast Iron line. Depth 4' and 12'. Once finished the guys said what did you say the technology was....I said ole Alabama Acoustics....similar to what the US Navy uses but on a smaller scale. One of the old school boys said I never would of thought someone in Alabama would bring this type technology to us, and I said Kinda like Bama and Auburn with Football right ?? No worries we got your back like your got ours right ? We will be getting a purchase order for 10 units and they are not cheap by no means. Good day in Texas and they did embrace the technology.
