Not actually the beach . . . . it's the exposed lake bottom due to the drought.

I am not an expert with the PI's. Andrew, a long time user of both high end PI and VLF detectors believes the results are impressive. I trust his expert opinion.

The lake bed is not fluffy beach sand, but rather oolitic sand or calcium carbonated brine shrimp sh**. . I love my Jr High School Geology Class.

Oolitic sand is an unusual sediment that is found in and around the Great Salt Lake. Instead of forming from grains of mineral fragments washed down from higher ground, this sand formed within the Great Salt Lake. It is composed of tiny, lightbrown, rounded oolites. An oolite has a shell of concentric layers of calcium carbonate that precipitated around a nucleus or central core. The nucleus is usually a tiny brine shrimp fecal pellet or a mineral fragment. Oolites form in shallow, wave-agitated water, rolling along the lake bottom and gradually accumulating more and more layers. In addition to the Great Salt Lake, oolites also form in Baffin Bay (Texas), the eastern Mediterranean Sea, the Persian Gulf, and the waters surrounding the Bahamas. Although oolitic sand is collected for its uniqueness, it has also been used to dry flowers and as flux in mining operations.

I believe there is a difficulty level much higher than 'beach sand' associated with the GSL. Pinpointers have to be detuned to the gray layer or you get a solid signal. There is also a black layer that i'm pretty sure isn't allowed in California and would come with a user warning. It stinks really bad and doesn't come off easily from anything in comes in contact with. Of course, you understand the salinity of the GSL is 3.5-8x greater than the ocean. The clencher is that regardless of how things are in the rest of the world, at the GSL, the new VLF's outperform the PI's on depth AND discrimination, which is unusual.

Not your thing - understandable.
