Garrett Axiom Finds Gold right through a Hot Rock. 

My Staff and I had recently hunted an area with our VLF's and found a few in this exact spot. I came back with the Garrett Axiom, as I knew the site had many Hot Rocks and sure enough. The VLF's missed this specimen as it was right under a big hot rock. Power of the Pulse Induction Axiom to be able to ignore the hot rock and get the specimen. Some PI's can ignore Hot Rocks and find gold nuggets because the nuggets are solid. Most PI's can't do the same under a large Hot Rock and still find a gold specimen. Chalk one more up for the Axiom Metal Detector's technology.
