I have been using the GM1000 for maybe 20 hours, covered some (often difficult and shifting) ground and found what I normally would find, mostly trash, most interesting so far an old key. So far so good. It is not impossible that there might be some gold to find, but highly unlikely. I am trying to dig every clear signal.
I am mainly out to find meteorites, and I am still unsure how not to overlook a possible meteorite.
Very, very often I would get a clear signal with iron characteristic. When I remove the ground cover, it often slowly fades away. Not sure what that is. Sometimes I do find small corroded iron crumbs (then the signal does not fade). But most often nothing.
Also, very often the GM1000 would give a really strong signal, but it is not possible to localize, because it just fades away even before I notice if it was an iron signal or not. I assume due to the auto tracking, so this might indicate a hot rock.
But what would I have to expect from a meteorite? If there is iron, also as quite tiny grains, the signal should not just fade, is this correct? So I do not have to worry about the signals from hot rocks?
Thanks for help.
Pictured is a 15 gram meteorite fragment I came across while detecting for gold nuggets in the Arizona desert today, in an area with no recorded meteorite falls. The stone is from a relatively recent fall; the primary and secondary fusion crusts are still quite black and unoxidized. Now the real fun begins: searching for more fragments!
Searching a new spot in the sunny Arizona desert this morning netted 3 small nuggets. While aimlessly swinging the mighty Zed back to the truck for lunch, a faint signal stopped me cold; what at first glance appeared to be a small magnetite hot rock turned out to actually be a meteorite fragment. After lunch, the Zed went to bed and out came the Gold Monster. While searching for more fragments, the GM 1000 signaled with a strong non-ferrous target response that turned out to be another small gold nugget. All in all, a fantastic day.

Heard the news lately? Today a fireball exploded over SE Michigan and registered a 2.0 earthquake.
Now, since we know the rock exploded, how to find the meteorites on the ground ,if they made it that far?
I always heard that when the meteorite light goes out, the rock can still be 5 miles high?
So, how would you trace it to where the rocks fell to earth exactly?
It was seen in 6 states and Canada.
