Look's like White's got a patent for a P.I. machine last year

looking through the U.S. patent office site ...saw this


[patft.uspto.gov]


look's like it talk's about high energy& sensitivity and helping in determining composition of metal!!!

Good homework Keith. You have been busy! Interesting read. Now.....let's see what transpires.

that will revolutionize current P.I. technology...I believe with the Microprocessor's available now day's there should be the ability to accomplish complicated algorithm's that was impossible a few years back...Getting a P.I. to disc is difficult by it's own principal design but should be doable in this day and age....

About 6 months ago there was an opportunity to buy this detector for a few hundred dollars. I was trying to bid on it but the seller ended the auction early (the price was only $27) and I didn't have a chance to bid as I was waiting until the end of the auction. I contacted the seller, who works at a pawn shop, asking him he would sell it to me for $100 he said sure, then he backed out when someone from Europe offered him $500, but that deal fell through and he then contacted me months later asking if I was still interested and I said yes, then he would not write back to me for weeks, then again asked me if I was still interested, he was asking $200 so I said sure. I asked him to test it so I know I am getting something that at least turns on. He said he will, and I haven't heard from him since. This is a discriminating military PI unit, that is submersible to a couple meters.

Also, I found this report that tests all of the top military PI units for detecting mines, very rigorous and scientific testing. The detector I was looking to by the supposedly the best by looking at the graphs.

I think this report would be interesting to anyone, in would be interesting to see Tom's opinion on how well these compare to the hobby line of detectors. I am also going to repost it as a new thread.
