(meteorobs) Meteorites Galorie in Kansas (Wired Science)

This device is typical of many previously designed large metal detectors for 
wide area search.

Easily made but most prefer individual hand held wide scan loops. Towable 
devices were and are easily made using any of the principles:

1) Balanced induction Bridge - Mine detection, Ferric & non-Ferric
2) Receiver/Transmitter - set for non-Ferric mode or Ferric mode
3) VLF - ground cancelling, Ferric mode (all metal)
4) VLF - ground cancelling, Non-Ferric mode
5) VFO variable frequency oscillator - Audible Ferric & Non-Ferric detection
6) VLF Discrimination - Non-Ferric mode
7) And the list goes on.....

His novelty is that he is doing it on camera for notoriety. Anyone can do 
this kind of detection, and it has been done as early as the 1950's with the 
first commercial metal detector made by Detectron which was a R-T coil wound 
to nullify a modulated RF signal when no Ferric or Non-Ferric metal was 
present. Nothing new......... Coil size and shape can be anything.

I started in 1956 but it was just for relics & coins....not meteors. It is a 
certainty that I discarded meteors looking for pioneer artifacts. Many were 
black encrusted stones. So too were the many that were of magmatic origin. 
And this was also true in the late 1990's when I searched desert ghost towns 
in the arid areas of Nevada, 40 miles from nearest decent town & water. This 
stuff is for the hardy... the dangers are (very real) in desolate badland 
exploring alone, OR with a pardner. Snakes, Scorpions, and brush covered 
well holes especially are daily threats. A modern mobile phone would have 
been nice, and would be essential now. Not having a shower to wash sweat 
before crawling into a sleeping bag* (*IF it was cold) bothered me the most.

Somewhat off topic...but the illusion of just a lot of fun is simply not 
true. I know.

If you get Wired Science on PBS, you might want to check out the last
10-12 minutes of the program. It's about finding meteorites in Kansas.
More meteorites have been found there than any other state. One fellow
uses a surprisingly effective technique.

               is a Christian Country". Mark Twain countered with,
   "But so is Hell. And we don't brag about that."
