Hey it's Gold, but the detector wouldn't beep on it!!!

Aloha all, hunted a family beach yesterday and while wading I noticed something shiny a few feet away. I ran the detector over it and NOTHING. No signal, not even a scratchy sound. I bent over and picked it up and it is a 14K hoop earring that has ben bent over in half and eveen looks like it was chewed. It weighs .6 grams, but would not give a signal. I also found a sterling smaller earring that weighs .5 grams and half of a sterling toe ring that weighs .4 grams, so why wouldn't this piece of gold give off a signal? Anyways also ffound some junker rings and necklace, it was a short 2 hour hunt. Aloha

Re: Hey it's Gold, but the detector wouldn't beep on it!!!

I don't know which machine you were using but small gold earrings especially if they are open are very hard to detect because of their low conductivity. If you were using the 1280 you might possibly pick it up if you turn the Discrimination to zero but I doubt it will even detect it then because the frequency of the 1280 is only 2.4khz which is to low for good detection of small gold. Higher Frequency machines like the Tesoro Tigershark or any detector that runs in the 12khz and higher range could easily detect it. Now if you were using the PI Pro it most likely would not pick that small piece of gold up either as small gold needs very short pulse delays to be detected and I believe if I remember correctly that the PI Pro only goes down to 15us. To detect that earring you would need to be down around 10us. However there is a downside to that. At a 10us Pulse Delay a PI will also detect saltwater. The short 10us would work fine in Freshwater. But 13-15us is about as short a delay as you can go for Saltwater use. You might want to try running the earring under your Ace 250 with the Discrimination turned down. Even though it is only a 7khz machine it might be able to detect it. These are the reasons that a Tigershark is the Freshwater detector of choice. It's high operating frequency gives it exceptional sensitivity to small gold and chains. But in and around Saltwater it's not even a contender. We always end up having to make some tradeoffs with our detectors. Most detectors give up some degree of sensitivity to small gold in order to operate well in the Saltwater environment. Hope this helps to explain why you werent' able to detect the earring.

Yes, I'm using the PI Pro here in Hawaii in the salt water. I've found several gold rings weighing .8 or .9 grams with less mass than this earring. Strange. Oh well, who wants little gold anyways :laughing7:

I want Lunkers.. Thanks for your input.

PI's love rings even small ones. The Eddy currents set up in a ring last a lot longer than those set up in other metal shapes. You can try this test. If you have a hoop earring do an air test with the link open and then do it with the link closed. You may not get a signal at all with it open and if you do get one it will be weak. But when you test it closed you should get a much stronger signal. Te more you learn about your detector and what it can and can't do the more successful you will become at finding gold!!!!

Well I've been metal detecting for well over 30 years now and 18+ in the water. This is the first Gold earring that I actually saw that didn't ring out on the machine, maybe it's made of paper

I have been detecting almost as long as you and almost all were both land and water hunting. Now I only Beach and Water hunt. You would be amazed at the amount of small gold that you walk over that you both you and your detector do not see

I have two detectors that I haven't found a piece of gold jewelry small enough that it can't see it but neither one is worth a darn in or around saltwater. But they do a number in the lakes

Both can see gold jewelry down to 0.5 grains. And while small jewelry isn't worth anywhere near what a nice wedding ring is worth it all adds up in the end. Plus part of the fun of detecting for me is to see just how much gold I can pull out of a lake after everyone else has given up on it

You got that right. The ring in my avatar I found right behind a guy, he walked right over it moving so fast. I just wonder how much we mis though

?

Read about a guy that took a gold hunting machine to the beach and cleaned up on Micro gold jewelrey, its just to dang small for a common detector

And that would make a Good new topic... I wonder who or how many people have used Gold detectors at the beach and how successful they were. HHMMMmmm

They work great in the dry sand but not out on the wet sand. When hunting the wet salt sand with a single frequency detector you have to use the Discrimination control to eliminate the effect of the salt. Unfortunately the level of discrimination where saltwater is rejected is above the level at which small gold is rejected

But in the dry sand or in a freshwater lake they are amazing. The first time you hunt a lake that has never been hunted with a gold machine you find a tremendous amount of small gold jewelry as well as chains and bracelets. The first year I used a gold machine to hunt lakes that had already been hit hard by the waterproof machines of the day I ended the year with 435 pieces of gold. It was my best year ever. I have never been able to equal that year as all the makes in my area have now been hunted over and over again with gold machines. I think if I want to another state where the lakes had not been hunted with nugget machines I could probably come close to that total again. I have a picture somewhere of a big glass salad bowl with all the gold in it that year. I will have to see if I can find it.
