Teknetics Forum

I've been looking online trying to gather some TID's for the T2 and also did a test run with a number of items. I'm sure there is a similar post on this forum but I couldn't find it. If some of you could post what you are getting for Gold and Silver (older coins, etc) that would be great. I read that gold can/will fall into the 44-53 range, but just about everything I tested was from 58-78. It was all bigger stuff though. I did try a 10K gold necklace and barely got a reading - it came in at 46. Everything else hit solid. I've wondered if there are ID's that I can/should ignore. From what I can find 40-43, 50-56, and 60-72 seem to be mostly junk. Please correct/help me on that if you can. Thanks!

Info found online:

OBJECT & Target ID

foil from gum wrapper 40 - 55 *Most gold jewelry is small, and will tend to read in the 40-60 (44-53) range.
U.S. nickel (5¢ coin) typically 58
aluminum pull-tab 60 - 75
aluminum screwcap 75-80
zinc penny (dated after 1982) Typically 78
aluminum soda pop can 75-80
copper penny, clad dime typically 83
U.S. quarter (25¢ coin), clad typically 89
50¢ coin, modern clad typically 92
old silver dollar coin typically 94
US silver Eagle $1 coin typically 95

My test run:

85, 5, 2+:

10K Gold Necklace 46 (barely got a reading?)
Foil 49
Small Gold Ring 57
Nickel 58
Alum. Pop tab 58-60
Gold Ring x 2 (could be fake) 58
Gold Ring (could be fake) 73
Gold Wedding Band 75
Gold Class Ring 78
Zinc Penny 78
Wheat Penny 79-80
Silver Ring .925 79
Silver Ring .925 82
Copper Penny, Dime 82-83
Quarter 89

Upon further review, perhaps 40-59 = dig, 60-72 = ignore, and 73+ = dig???

I hate to sound like a wet blanket...but gold can show up anywhere from high iron......to a penny. There is no best range for gold, unless you expect to pass up certain gold targets, while trying to figure out a cherry-picking routine. Not that I blame you for trying to pass up on as much trash as possible. And if all your ID testing was done in the air instead of the ground, your going to miss even more targets. Air ID's can vary widely from ground ID's. Especially with the T2, as its ID ranges have a bit more play/variance than other detectors. FOCUS ON THE TONES, NOT THE VDI NUMBERS. The vdi is just a helper, not the determiner, of what a target may be. The tone is the determiner.

50 to 63 readings find the older smaller coins. I'm not saying dig those numbers for everyday hunting.. Only if potential Half dimes Three cent Silver etc are possible finds.

I dig all repeatable signals especially when the target id numbers are tight
dug a silver band yesterday at 71 solid
The large gold ring i found a couple of weeks ago rang in 55-57

haven't found any half dimes but the i.d. chart that comes with the minelab sovereign lists them in the zinc penny, indian head range. i've got one somewhere that i could check on the t-2

I appreciate the info; I'm trying to get better at the tones. I def. know when I hit iron! That grunt is easy to pick up on... A lot of the places I hunt have so much 'stuff' in them that the tones are all over the place and I've tried to use 2+ and be consistent. Most of the high pitch tones that sound great end up being an overload - pop can, etc.

It helps to see what some of you get for ID's for certain items. It does seem that gold items can be in a range of numbers and that silver can vary also. Good idea on repeatable signals and tight numbers.

Thanks again!

One number that hasn't surprised me yet is 59
Its always a square pull tab
but this is not to say i don't dig them, but so far always a pull tab with a nice hi tone and tight response.

any tips on avoiding these such as the bottle cap trick ?

3 tones will get most coins inclding nickle as high tone. zinc comes in lower tone so indian probably will too but i haven't found any with the t-2 yet

I had a good day today (by my standard); as suggested, I only payed attention to the tones and didn't even look at the ID #'s. It made things go a lot better for me. Before, I would look at the number and think, should I dig or not..... Today I dug every solid tone.

16 quaters, 11 nickles, 8 dimes, 16 penny's (1 wheat), three pieces of costume jewelry and a bunch of pull tabs, lots of foil and about 5 pop cans

I would say you had a great day.....by most detectorist's standards. Congrats......

= When to and When NOT to recover a target.

Naturally, a lot depends upon your personal desire to find stuff, ability to select different sites, and patience level.

That's a good way to learn what any detector can do, but ... it is usually tested in a clean environment, even to include air testing with out the ground mineral signal, and where targets can be at odd angles, varying depths, and too often located close to a masking piece of trash.

Well, here are some quick tests I did, air tests, using an assortment of targets in my sample kit I took with to go do two GPAA Gold Shows this past few weeks.

Teknetics T2 w/11" DD coil:
'94' .. Morgan silver Dollar
'91' .. worn Seated Liberty 50¢
'83' .. '70s Lincoln 1¢
'78' .. Zinc 1¢
'77' .. Indian Head 1¢
'77' .. Wheat-back 1¢ and Indian Head 1¢
'75' .. Indian Head 1¢
'73' .. silver 3¢
'66'-'67' .. 1858 Flying Eagle 1¢
'58' .. Buffalo 5¢
'51'-'53' .. Nickel 3¢

A few women's and men's gold rings came it at:
'38', .42,' '47', '51', 54', '56', '57', '58', '59', '60', '62' and other varying read-outs.

Rings range across a broad assortment of thinness to thickness, narrowness to wideness, different alloy content, and from round bands to odd-shaped with larger, broader top parts. Very broad range of VDI numeric read-outs. That's just rings, and when you add gold and silver chains, pendents, charms and other items, there is no way you can narrow them down to any number or range of numbers.

What to ignore and what to dig? Well, I class two types of hobbyists or two types of hunting as follows:

Some folks are what I call Traditional Coin Hunters and others I call as Avid Detectorists.

If you are casually looking for coins and some occasional gold and silver jewelry that might respond nice and proper simimar to commonly found coins, and you're hunting more coin based locations and want to eliminate recovering most trash, then you can trust the TID and VDI readings a little more and sort of "cherry pick" any site.

If, however, you are a more avid hunter and determined to seek more out-of-the-way sites, find and hunt some older coin potential sites, have a desire to find far more jewelry and look for older coins, then I suggest you set the Discrimination just at the point where you barely reject an iron nail on the ground. Then, patiently search an area and recover all target hits that do not sound all iron like. You can glance at the TID and VDI to get an idea of what you will recover might respond as, but the determination is to recover any good-sounding audio response targets.

Today, for example, I am stuck in town, don't have any good renovation sites to hunt, and will limit my detecting time e periods so, it's a lay-back day of 'Traditional Coin Hunting' for me. You have to make the call, but don't get tool hooked on TID and VDI readings.

exellent post monte hh

Monte,

Thank you so much for your time and advice. It helps more than you know. I've been working a playground the past two days and have found about $10 worth of clad, four costume jewelry items, 1 wheaty and a few 1965 dimes & quarters. One year off.............. I've dug every solid signal above 40 and there is a lot of foil in that spot! I don't mind the pull tabs. To make that part of the experience a little more enjoyable, I decided to make a donation to St. Jude Children's hospital for every tab I find. So, when I find one now I know that I'm doing something that really makes a difference.

Thanks again! I'm sure the info here will help others.

Scott

Monte, thank you a lot for that information, Just like you mentined in the last seminar, I will set my disc to reject the nail and dig out everything alse.
My wife and I enjoy the seminar it was the best thing ever for us. Hope your surgery goes well. My wife and I are prying for your soon recovery.
thank you!
Abel and Connie.
