… Metal detector hobbyists consider themselves lucky when they come across an old button or coin instead of just the usual old nails or scrap metal. Amateur treasure hunters, however, don't even dream of finding the type of thing that set off Jegor Klimov's metal detector in Saaremaa earlier this month.
Among the items found at a 1,700-year-old sacrificial site were luxurious local crossbow brooches, some made of silver, some gold-plated silver, as well as Scandinavian-looking belt plaques with silver plates, writes regional Saarte Hääl (link in Estonian).
The most unique item to be found at the site, however, is a massive gold bracelet or collar from the 3rd century.
"With this find, the signal was sort of indistinct, sort of heay," Klimov described. "I doubted whether or not to dig. But here it is! It's like winning the jackpot! Unearthing something like this is amazing. And it is amazing for Estonian history too, because nothing like this has been found in Estonia before. Gold finds are rare in Estonia to begin with; we know of just four or five finds. But this is the coolest of them all." ...

In forty feet of water off the coast of Boca Raton after Dorian a scuba diver found an iPhone that was lost by a boater 20 miles south near Hollywood Florida about a year earlier.
Remember that iphones will trap air. They are water resistant. Some have a water-proof case. That means trapped air and buoyancy.
The same thing happens with watches, which can end up in areas where less dense things tend to accumulate.

Concerning the one mystery item I posted yesterday Sebastian Steve said, My guess is a clock, and not that old as it has phillips screws.
Anybody else?

When we talk about discrimination we are usually talking about discriminating a particular type of item or items made of a particular type of meta.. There was at least one metal detector that provided an option that you might call stratigraphic discrimination. The metal detector I'm talking about is the Tesoro Royal Sabre that, which was sold in the 1980s and had a number of nice features, one of which was Surface Blanking. It also had notch discrimination and reject. Not bad for an 80s detector.
The online manual for the Royal Sabre says of the Surface Blanking Battery Test Switch - This switch is used to control the surface blanking function, and to perform the battery test. Surface blanking is used to eliminate the detector's response to good targets which are shallow.
I used the Royal Sabre some over the years and up until the time that they refused to honor the advertised Tesoro Lifetime Warranty, but I only used the surface blanking function a few times. One time that I remember using it was on a very trashy site where it appeared that a cabin or shed of some type once stood. It blanked out a lot of loud surface signals and permitted me to pick out smaller signals, such as coins between the surface trash. Surface Blanking might seem like a good idea in theory, but I never got a lot of use out of it.
Wikipedia says, Stratigraphy is a key concept to modern archaeological theory and practice. Modern excavation techniques are based on stratigraphic principles. The concept derives from the geological use of the idea that sedimentation takes place according to uniform principles. When archaeological finds are below the surface of the ground (as is most commonly the case), the identification of the context of each find is vital in enabling the archaeologist to draw conclusions about the site and about the nature and date of its occupation. It is the archaeologist's role to attempt to discover what contexts exist and how they came to be created. Archaeological stratification or sequence is the dynamic superimposition of single units of stratigraphy, or contexts.
There are times when I do what could be called stratigraphic discrimination, but I can do it by listening to the signals and using the brain for the processing rather than letting the electronics do it for me.
I don't recall anyone talking much about using Surface Blanking, and I'm not aware of it being provided by newer metal detectors. While I can see the theory, I don't know how effectively it was implemented in either the technology or practice. For me, I'd usually rather remove the surface trash.

Like Elvis, Karen has left the building. Only Lorenzo remains on the Atlantic National Hurricane Center map. We are having some big tides now.
Here are the surf predictions.
Happy hunting,
