I am going to be making a trip here shortly to northern Az. to hunt meteorites. The questions I have are what settings should I be using and program for the V3i, second question what would the best coil to use on my detecter with the progam I should use, I have been told the whites GMT would be a better unit for this hunt but would like to try my V3i I also have a Dfx which I will be taking along to see if that will also work in the meteroite fields. Any help would be appreciated Thank you
