I had heared somewhere that wet soil brings more depth to anything that develops a large "halo" ie, copper and especialy rusted iron/steel. and that dry soil allows more seperation so you hear the silver better and not so much rust noise.
Now were talking about conductivities thru variable materials rather than near constant ones, ie an uncontrolled copper/copper oxide mix. and also, what are we trying to conduct thru these poor orphaned underground mixed blobs? I hear the term eddy currents but dont know what it means. Metals (generaly) conduct several types of energy such as sound, heat, and electricity. When coroded, they still do this, but not the same. Remove or add water and it changes even further. In addidion after changing them they may conduct different energys differently; meaning possibly better conductors of electricity and worse conductors of sound. Now add in other factors of varying significance, temperature being higher, anount of skin oil left on the coin when dropped in 1910 being lower...
I am currently a senior ME student at UWM, which means I do know scientificaly how some of this works, but not knowing all the concepts involved means I know just enough to realy mess it up with out realizing I'm wrong, and present it in a credible enough manor so that others will beleive Im right.
I guess what I'm trying to say is that I dont know, and I havent experianced anything to make me lean either way, but my gut feeling is that soil moisture does bring greater depth capabilitys, and lack of soil moisture probably could create some advantages as well.
As far as spring comming, no doubt I 100% cant wait!
If you realy want to find the good stuff Dan, do what I did; come to wisconsin, get Gen.Ray and bring him to your sites. He will show you where and how you should have been searching all along! <img src="/metal/html/wink.gif" border=0 width=15 height=15 alt="
