Subject: Re: X-5 In Arizona--- my 1/2 cents worth
In reply to: Ralph 's message, "X-5 In Arizona" on 10:02:30 09/15/02 Sun

The X-5 and MXT I believe(?) are running around 13-18 kHz. If manual,or automatic, not important; both the packaging and operator skill are crtical.

A good test of any VLF-type is in the heavily mineralized areas of western Nevada. The iron-oxide clay bedrock and the alkali overburden really require skill and perserverence. And in my opinion a real close to neutral ground balance; no positive or negative bias. The machine should be simple and without frills; just basic and housed in a small compact box (Such as Fisher Gold Bug)

However, I feel that the "lower freqency" of the X-5/MXT a good all-around choice. It is not by accident that gold machines such as the original Gold Bug, the Lobo Supertraq, Gold Scanners (Compass), as well as other "veteran" detectors operating in the 12 to 20 kHz range have been so well received over the years. They not only are good performers but are for the most part simple to use and in a good package.

In this list I would also include the Minelab 17000 hooked up to a 6-inch circular (note: I said "circular," not elliptical) and used in 32 kHz. Also, the GB-2 (70khz) hooked up to the 6.5 concentic eliptical is able to perform in many of the less alkali areas and can find the smallest specks in the top inches of dirt.(Incidentally: There are some broad volcanic-alkali areas in parts of western Nevada that even tax the PI-types.)

Actually, I hope the latest detectors, such as the MXT and X-5 perform. There are hundreds of square miles of pediment in Humboldt/Pershing counties where small crimbs to large lunkers are scattered--- maybe only a few to acre, but seen to be in some sort of orientation; but initially found in "hit or miss detecting."

However, a "wild card" looming on the horizon is the continual "gold machine" improvement in PI-type technology. I expect to see more manufacturers designing/producing PI machines in the near future. I cannot understand why White's so slow in this respect. (In great respect for Olive and Ken Sr.; Olive would have directed Ken to design a PI which he would have; and then she/Ken would have gotten together with pal Wayne Winters and found gold with it. It was not by accident White's has became one of the Industry leaders; it was greatly influenced by the late Olive White and her farsightedness during the critical 1964-72 period.(Ya gotta keep up in in the cutting edge of R&D or lose out.))
