Hi,

Has anyone done any tests to determine the smallest gold nugget that either the AT Pro or AT Gold can detect? I currently use an Infinium (great machine) and am considering a VLF machine to go with it. I really like the fact that these two machines are water-proof like the Infinium, but have concerns about their ability to compete with the likes of the GB2 in finding small gold. Any info would be appreciated.

The AT Pro will hit on gold down to a couple grains with the small coil and the AT Gold with small coil down to about a grain. GB2 will hit gold weighing less than 1/10th grain.

I found this video on YouTube, gold prospecting with AT Pro in a creek.

Thanks for the info. Is the small coil you talk about for the AT series the 4.5" sniper?

Yes! That is the one.
