I'd love to see you try that test with the measly lil Tesoro Mojave.
It best every machine I own in nails.
The Compadre as well.
I own many machines.
Minelabs, Garrett, White's, even the lil Simplex.
I wish I had picked up the Tesoros years ago before they crashed.
The Mojave is my primary machine around fence's and homes surrounded by nails.
My Sovereign GT does quite well in nails. Though not as good as that lil Mojave.
I've even heard it's found nuggets others missed in Australia.
I did enjoy your video.
