Tesoro Sand Shark

[TORRERO]

So Sorry !!
I got a Pulse Induction Sand Shark, not a Tiger Shark...

Just got a Tesoro Sand Shark yesterday and was running some air tests today on some 18k
gold items dug in Spain years ago.

I was hoping that this machine would pick up the Rope Chain, but it will not.
I does pick up the clasp though...

Here is how it air tested on all this stuff.....

Big Gold Christ Head at about 10 inches
Small Gold Christ Head (solid) at about 8 inches
Big Gold Sharks tooth, (clasp & mount 18k) at about 6-7 inches
Small Gold Sharks tooth, at about 3-4 inches
the Gold chain clasp at maybe 1-2 inches
and the Chain itself would not respond no mater what I did...
stretched out, or piled up or even when I tied it in knots....
The Rope Chain is about 30 grams of 18k so worth today about $1800

Anyone know of a pulse machine that could actually pick that up ?
anyone can actually show airtest results?
I used to have a Tesoro Stingray that would blow your ears off on something like this..

any and all comments welcome.

Re: Tesoro Tiger Shark

Unless the chain is curled into a ball in the dirt or sand, it would be hard for any detector, pulse or VLF, to pick it up. A stretched out chain is difficult for any detector to hit.

Most detectors, like yours, will sound off on the clasp, though. That's how most chains get found.

So sorry, it's the Sand Shark, and I had a Tesoro Stingray years ago that would have blown your ears off on that chain...
I would suspect that the Tiger Shark would do the same...

I have the Tiger Shark and it will go off on those thin gold chains clasp or not. It is the only one of my detectors that can see those chains. But it also find the smallest foil or bird shot.

Here is an example of one I just found. For reference, the heart is smaller than a dime and the necklace was complete so that may have been the reason I found it. It was found about 3" down under the sand in the water (fresh water lake) and was just a whisper of a change in tone with my Sand Shark.

I just took the neckace downstairs and did an air test. I could only hear (barely) it within an inch of the coil. Settings were Pulse 75% Volume 60% and in VCO for the test. (The same settings that were used to find it in the water) So as others have said, don't put a huge amount of credence in air tests.

When I first got the Sand Shark, I was very disappointed in the air tests I ran.... but am quite pleased in all that I have found with it in the water.

Just to see if my (new) CZ-21 would pick it up with an air test, it did BUT didn't do much better than the Sand Shark (air test). On the CZ, I had the volume in boost also.

I have found though with such faint signals, you must be paying attention AND moving low and slow. Works for me.

It came up with the pendant ?
If you look at all the pictures I put up the smallest thing is the clasp, and I could hear a faint but clear
sound over that.
I am sure it would have picked up the pendant.
I remember in Spain (1994-6) we used to dig a chain regularly with some type of medal on it.
But we always got the chain because of the medalion... and the chain came with it..
I have always wondered how many items of Gold lie right under our feet but we can't get to them..

But I only once dug a chain by itself, using the Tesoro Stingray it was smaller than that rope chain, but solid...
and it was dark outside and we were walking along the medium tide line when I got a faint signal and
reached down and got it out of the sand, we did not know it was gold until we got home.
I still have it, in a SDB but will break it out to test this when I get a chance.

Yes, it came up complete as you see it with the pendant. The next day, same beach, here are some other examples of what I found. The one was only a few (4?) links of a chain. The only way I got these small items with my scoop was I would walk to shore and dump the contents at waters edge and use my propointer to locate them.... I had been chasing the signals in the water and they were going out of the holes in the scoop. I just had to know what they were. Sand Shark hit on all of them but faint signals.

That 14k ring, how deep was that ?
did it sound faint or real good ?

 

[cdv1]

That 14k ring was in the scoop with a dime. It sounded loud and was less than 3 inches deep, but that isn't a fair comparison since I did find it and a dime in the same scoop. Actually I saw the dime and then noticed some yellow around it. In my opinion, the Sand Shark will find small chains but that relies mainly on the user and how it is used. If you don't take the time to learn the machine, If your hearing isn't good enough to pick up what the detector is telling you, IF you don't swing the coil over the chain (low and slow) OR you are to distracted by the scenery, you will miss the small stuff out there.

Hi Richard! Air tests don't mean squat, period. You use air tests to recognize sounds, set up your machine, and to learn discrimination capabilities - they are not accurate for depth or target size. I have found three gold chains with no clasps in 4"- 7" of wet sand with my Sand Shark. One of them a Garrett Ace 250 could have found - a 28-gram 'Cuban" gold chain! If the chain is fine and stretched out, there is a good chance you'll walk over it with a PI unit more times than you would with a VLF. But the VLF ain't going to get it in the wet sand either!
