This bar currently has a bid of over $4000 and the auction has just begun.
In the very early days of Spanish exploration in the New World, Native American artifacts were melted down for transportation back to Spain. The melted materials were often cast into bars that varied widely in the amount of gold and other metals. These melted metals were referred to as Tumbaga.
In a Tumbaga bar there might be as much as 97% gold or there might be as much as 97% copper. Mixtures of gold and copper containing a lot of copper can be very brittle and will easily break.
I still think that IF Spain can claim the treasure of the Nuestra Senora de Las Mercedes after it was recovered by Odyssey, that the native American groups actually have a more just claim.
In my last post I was talking about watches. I mentioned that detectors might have a tough time identifying a watch. Watches come in a lot of varieties and I don't know how you could expect a detector to correctly identify a watch.
I also mention from time to time that it is important to know your detector and how it responds to different situations and different targets.
I decided to a little experiment to show you something.
I took four watches. The first, which you will see in the video, is a small cheap women's watch, like a Timex. It has a non-metallic band.
The second watch, going left to right in the video, is a large men's Seiko.
The Third is a dive watch. And fourth is a ladies stainless steel Rolex.
First I set the Excalibur on discriminate mode. Then I set the discrimination setting on 15.
Watch what happens when I pass the coil over all four watches. As you might expect the high discrimination setting results in a relatively small signal. Using this setting you could easily miss all four watches, especially the dive watch and the Rolex.
These watches are not buried either, so take that into account.
Then I moved the discrimination setting back to about 10. As you would expect, the signals are better, but on some watches not really very good yet.
Then I set the discrimination on 1, and, as you can see, the signals are better. You probably would be able to detect all four watches with this setting in field conditions.
Here is the video.

How the watch lays is also important.
You might have noticed that the Seiko gave a much louder signal when the coil was angled to detect more of the face of the watch than when the coil was directly down on the edge of the watch.
The Seiko large band was also giving a signal something like a long elongated object would since the band as laid out like that.
I highly recommend that you experiment with your detector and different uobjects under different circumstances. Learn the different sounds and what they are telling you and learn the results of different detector settings.
The more variations you try and the more you experiment, the better off you will be.
If you come across a nice watch you don't want to be fooled by your detector.
As I've said before, I usually use pinpoint or all-metals mode on the beach, no matter what detector I am using.
Well, beach detecting conditions remain pretty much the same. I don't see any significant changes coming for the next few days.
The wind is east/southeast and the seas running around four or five feet.
Nothing promising.
Happy hunting,
