Steve. Great post. I have friends that I detect with using 2100/2200/GP as well as an assortment of VLF-type) and it is the persistance of the user that are the bottom line.

In some ground the VLF-type are the "best." In other ground, more iron-rich or alkali, the SD-type are the "best."

In some areas where small sub-grain flakes abound, it is the VLF-type (actually LF's above 30kHz) that are the "best;" in other ground, where deeper and possibly larger nuggets may be found, the VLFs from as low as 4.5 to 30 kHz that might be the "best."

Actually, over the past 20 years I have tried to figure out ground mineralization and find it does not listen or conform to our "textbook" theories and suppositions.

Ground mineralization very tricky. In some areas you figure you can go down deeper, but actually hit a "barrier" which kills you at near surface. "Mineralization" varies greatly from sunny side of a slope to shady side; from a rivulet to a slope. Soils are complex: The parent rock-type and the weateherng both physical and chemical all are "wild-cards."

Hardpan, caliche, shales and shists, [true "ironstone" (aka the laterites of parts of Australia)] and the gossans of the cordillera all define the "best" machine.

As a graduate geologist (1954), and as your daughter can verify, the Mackay School of Mines do not hand out diplomas capriciuosly--- and as a soil engineer working for private soil labs I have studied soils; and as a mining geologist specializing primarily in the Nevada "Basin and Range Provence," the more I "think I know" about soils and ore deposits, the more I "know I don't know." (Reg Sniff, George Payne, and David Johnson are just a few with knowledge far greater than mine.)

In conclusion whatever machine is not as imprortant as you as the user and your persistance. So get out and swing that machine. The gold, from subgrain (crumbs) to multi-ounce (lunkers) are out there (and I understand a 30-ounce was recovered by detecting earlier this week)
