You have evidently been watching meteor men.
Seems like most of the meteorites they find aren't real deep, unless they are the real big ones. I would say that any stable machine in all metal mode would work just fine. They seem to hunt with the Fisher's.
Now to finding meteorites. Better than gold, that's for sure, but much much harder to find. I did a search on " Missouri Meteorites " and found a good site on this State plus many other sites. Do that kind of a search on your own State or whatever. Just maybe search "find meteorites sites" and see what happens. Whatever you come up with you can be sure that others have also done that kind of a search and found those sites and maybe even visited the sites. I would be willing to bet that any known meteorite site will be well posted and you will probably find a very irate owner of the property if he catches you there.
There are many meteorites striking the Earth daily. I know that up and down at the polar caps they are found because they lay on the ice. Most meteorites would logically fall into the ocean since there is more water than land. I would think that although they fall randomly, over a long time period they would fall everywhere on Earth. Look at the craters on the moon? That alone should tell you of the large amount of meteorites in the universe, but then again the moon has no atmosphere, our atmosphere burns many to vapor, although the larger ones do fall to Earth.
Those "Meteorite Men" have their own TV show, production staff; sponsors, etc. so they can get into areas that you and I would be coldly told "no", they strike deals with landowners etc. to get on the property. Also, simply entering one's property with a full production staff, cameras, etc. leads some credence to their credibility.
They are out there, but finding them is going to be really difficult.
