Thanks for posting. Looks like I need to drop back another 10 vdi's. Thanks!

On land I really only look for 75 and up...

In the water, anything above iron..

I have found plenty of gold rings in the low 40s, usually white gold...

And not that Ive found one yet, some of the most valuable ones will for sure be in the mid to low 40s, you know, the ones with a huge chunk of ICE!!

Some good information to know, thanks for sharing it.

1. What are some of your silver & gold jewelry vdi's that you've dug?
2. Do you have a set vdi that you dig if target is above that vdi?
3. I mainly look for gold & silver. I dig anything 50 & up. Has any of your gold & silver finds been in the 40's?

My AT Pro is programmed for low conductive gold alloyed targets not high conductive silver. It is programmed for the more shallow gold alloyed target instead of deep silver. My coil configuration is the more sensitive concentric coil. Size of choice for site environment - 6.5X9". I've never found a gold ring that VDI'd under 50. Earrings and earring backings, yes along with small charms. I'm not saying it doesn't exist or happens...I've some small rings and fairly large rings. All different shapes. All different sizes. VDI range from 50 to 66. You are forgetting or perhaps have not been taught one of the AT Pros important strengths...AUDIO. Dig it all concept? This is a great way to learn what not to dig. Dig "repeatable" signals? You will leave gold alloyed jewelry behind for someone else. What about the other precious metals used for jewelry such as platinum and palladium? 26 rings YTD for 2014...not all precious metals. I don't keep count on the pieces of jewelry I have recovered. I don't hunt salt water as I don't own a detector that meets the requirements for gold jewelry detection in seawater. The AT Pro is very capable of locating the low/mid conductive precious metals jewelry on dry ground and in fresh water. Good success to you and happy hunting.

Very impressive. Would you be willing to share your settings with a new AT Pro user? Thanks in advance.

If your not digging the 40's your missing gold. The smaller gold I found was from 41 to 43.

I've recovered many gold chains that read as low as 39. I've recovered a lot of gold that read from 40-43

Thanks everyone for the info.

Very helpful info here for new At pro users as myself THANKS.

+1....I have found many smaller 10k rings that came in between 41-44...most of my 14k`s came in 50-53....the photo is a 14k with .46 diamond I found last week..It came in a straight up 50.......HH

Page 21 in the Owners Manual..."Note: Target values can vary based on the orientation of the target in the ground, amount of ground mineralization, etc. It is important to practice in the field to learn how these factors can affect Target ID."

The Conductivity Chart on page 21 shows small jewelry, medium jewelry and large jewelry. What is omitted is micro jewelry. Since these classes are based on weight...I can say only I have not found a gold ring with my AT Pro that VDI'd under 50 with the configuration I use, the settings I use and the ground conditions I have. I have recovered many micro gold jewelry pieces that VDI'd under 50, just no rings yet. It is great, when it is considered...everyone has a choice what to dig and whether to dig. Gold also could come in the low tone iron range according to the conductivity chart provided by Garrett for the AT Pro. Where is the "break point"? What VDI number? Clive James Clynick in one of his hunting for gold jewelry methods books explains it, "Where a consistent, even sweep produces the same gold range VDI numbers--dig. Where you see the response dropping way down into the “foil zone,” --don’t get your hopes up. These responses are also less restricted to any given ranges."

Again the main reason being a difference in mass and weight gold rings versus junk such as tabs and foil. Indeed nothing is 100 percent but even if you cut the odds in half your ahead of the guy that walks right over the gold rings. Program the machine up to your advantage and hunt with it in areas you want to retrieve gold jewelry and you might be surprised. The At Pro is one machine that can be programed to your advantage. HH

Great information guys, thanks for sharing.

I think #51 has been Gold more than any other number for me, but Gold can be anywhere. Ring diameter and thickness play a part in the tone and VDI number too.

I scooped this one Saturday 8.8 grams of 14k white Gold and it was a smooth 53.



This one I scooped Sunday 4.4 grams of 14k and it was a 62.

May be a dumb question, but need to know. When you say repeatable single, do you mean a solid signal or number? Seems most junk, foil and tabs for instance, bounce around numbers but have a strong signal. Seldom do I get a signal that is a repeatable single number unless its a coin.

Forget you even have VDI numbers and just listen to what sounds good. I know the sound of a copper vrs a zinc penny.

I know what "round" sounds like opposed to a nail.

The VDI will keep you from digging good targets in the long run.

I dig targets without even bothering to look at the VDI numbers usually. I often hunt evenings and stay til well after dark. I am rarely surprised at what pops out of a plug, even after dark. I dig iffy signals, and nice crisp signals. I sometimes watch the vdi if I suspect multiple targets in one hole. I'm no pro, but after using a tesoro for a couple seasons, I feel like the vdi becomes an excuse for not digging. For me mding is more satisfying when I am digging, not leaving targets.

You have a very valid question. Make certain it is answered by someone experienced in finding gold jewelry in the same environment (land vs seawater vs freshwater). The methods used by relic hunters and coin shooters seldom get the same results as gold jewelry hunters.

This is exactly what "they" are saying. Think about this ...coins are flat and solid and round. Rings are NOT flat, they are NOT solid and VERY FEW are round. The only round ring is an undamaged band. Medallions are not round, bracelets are not round, chains are not round, earrings are not round. They are not flat..they have irregular shapes and they have holes in most of them. In some cases in relationship to the size of the target...BIG holes. Repeatable solid signal? In your dreams. Yep...dig only those solid repeatable signals and I'm the next detectorist behind you digging what you passed by, perhaps another nice one with diamonds.

This is why "they" don't post repeatable, on going results of that philosophy. "They" also say dig all foil signals or foil range, otherwise gold will be missed. I say everyone knows gold jewelry can fall in the iron range, anyone digging iron to cover that base? I guess "they" are missing gold jewelry by not digging the iron signals. "They" tell me I'm missing gold jewelry by not digging foil signals, yet it's OK to leave gold jewelry behind by not digging iron signals. ???? If a dectorist wants to believe the "popular" opinions and beliefs of others that is OK. The color of the day is going to be blue, tomorrow will be green, the day after purple and the next day orange. We'll vote on the color change for next week. (Everyone is doing it) Popular opinions can do that..change in an instant.

Is it no wonder the "dig everything" mentality end result is detectors lying dormant in the closet? I know if I had to dig everything at the start of my detecting experience, it would've been that way. I guess maybe it is a good way to get rid of the "competition". You decide.

Please remember YOU are not using the same coil or the same sensitivity or the same iron discrimination or the same ground balance procedure or the same mode as the next guy. You certainly don't swing the coil the same as the next person at a certain height and at a certain speed. Your ground is unique to you and is different than mine.

You can take advantage of the AT Pro and "tweek" it to enhance signals from low conductive metals and smaller than coin size objects or for high conductive metal targets, or even stay more "neutral". There are limits to the AT Pro as with any machine. There is no need to exaggerate the performance or the AT Pro's ability like so many people do. You decide your detecting philosophy, you choose the targets you want dig.

There have been people using the same machine you use that find the desired treasure you are seeking. They've done it on an ongoing regular basis. Choose wisely...what you seek, you will find. Remember a metal detector finds metal. The AT Pro does that job very well. Tell it what metal you want it to find. Be clear, concise and exact. My results speak loudly for me. Good success. HH 5560
