I recently discovered I have not posted enough to be able to do certain things on this website so I thought I may be able to add to this post.
The Gold Bug 2 is still a machine that can and still does out produce the Gold Monster and the Eqniox on the smallest of gold and even large gold. This simple two 9-volt battery marvel has likely accounted for more gold than any other detector in its 30 years. It would be interesting to see just how many patches have been discovered because of the first little bit this machine has sounded off on.
I was recently out done by a friend using a Gold Bug 2 and I using a Gold Monster tuned in the manual settings of course. The Gold Bug 2 is just unbeatable on small gold and specimen gold. I think we have to remember that huge nuggets like the Boot of Cortez were discovered with a Radio Shack version of a VLF and these types of machines tend to fall in the hands of people that are not experienced and not searching gold known areas so the chances are good that the VHF in the hands of unexperienced and experienced prospectors continue to be the discoverer of the first signs of a major deposit.
