2 Meteorites found on first day!!!

I bought this metal detector on Saturday and on Sunday went to a friends claim in the Bradshaw mountains to familiarize myself with it. Within 2 hours I found 2 iron nickel meteorites. I had found a meteorite in this area 2 years ago with a Goldmaster II so I had a "known" location to work. This detector picked up the 2 additional meteorites in the same area I had searched 2 years earlier!!! I am beyond happy with this metal detector. Goes deep.

Great Detector

Guest in Australia - best
This is a great machine but lacks sesitivity to small gold because it is an PI detector, the main claim to fame is that it works in highly iron mineralised ground. In zero to moderatly mineralised ground a Good VLF detector with similar power output and coil size will out perform it in all respects with the exception that it is not as sensitive to some hot rocks as VLF's can be.
