Hi,i have been out detecting this weekend.I must of dug up 18 ring pulls.my question is,having the imaging on the gti1500 is a bonus but if you are hunting gold then you will have to dig all ring pulls.also a gold chain stretched out would show as very large on the imaging.So if I'm right then the only advantage the imaging gives you is the size of the object and the reading.But lots of scrap metal show up on the detector as a coin.large cans normally give the overload signal so that's OK.But what signal would you get from a big hoard of gold coins in a pot and what would the imaging say it is.cheers Nigel

I have been out detecting this weekend. I must've dug up 18 ring pulls.
Only 18??
I never have so few.....
My question is: having the imaging on the gti1500 is a bonus but if you are hunting gold then you will have to dig all ring pulls.
You got that right. Pulltabs/ring pulls sadly share the same conductivity range as gold rings. There is a sort of a silver lining to this cloud, though, which is this:
The evidence seems to support that the ringed pulltab accounts for the fewest gold rings in the same range.
Something like only 15% of gold rings respond the same as the dreaded ring pull tab. So, if you are going to ignore any pulltabs readings, then ignoring those will allow you to miss the fewest rings.
...also a gold chain stretched out would show as very large on the imaging.
Not so. The detector - any detector - sees the chain as a bunch of individual loop inductors. So, rather than one large signal, it usually responds as if it was trying to see a bunch of small ones. This gives what one might all 'erratic' readings in the low range of conductivity.
So if I'm right, then the only advantage the imaging gives you is the size of the object and the reading. But lots of scrap metal show up on the detector as a coin. Large cans normally give the overload signal so that's OK. But what signal would you get from a big hoard of gold coins in a pot and what would the imaging say it is.
Cheers Nigel
By "pot," Nige, I assume you mean an iron pot. In that case, your detector would merely see a large iron object - and not the gold within.
Also, most people run their instruments with at least some iron discrimination. In this way, you could easily overlook such a stash!
Now, Imaging is a great advantage, one not to be tossed aside easily. This is because the individual items we seek - coins and jewelry, for the most part - almost always fall into a predictable size range. Given that, the Imaging is a great boon.
But, as with so many things in life, Imaging is not perfect. Many trash items can be in the same size range as the "goodies." That is the nature of the beast.
SO, if I were looking for a Leprechauns hoard with a GTI 1500, ah, well.... that is the time to open up your thinking.
I would set discrimination to iron accept, reject everything else and dig the larger objects.[/size]

The problem with chains, stretched out or bunched up - your detector only sees one link at a time, and always the one closest to the coil, which is why most chains are difficult to detect. Not withstanding what Dahut related, a large iron pot would most likely result in an overload signal and should be investigated if you are looking for objects that size. The imaging was designed for coinshooting not pots of gold hunting.

I don't own or use the 1500, although it is one heck of a machine and probably the best coin shooter out there. However, I do use my 2500 more than any of my other machines. Back when I first got it around ten years ago, I thought that imaging was the coolest thing, and it is a good thing. Although it is an imaging machine, I seldom use my imaging coils anymore. I prefer the double"D" search coils because they cover more ground at depth. Yeah, they may not get as much depth in non-mineralized ground as concentric coils, but I believe the fact that less or no ground coverage is lost at depth from toe to heel of searchcoil more than makes up for any loss of depth in non-mineralzed ground. Most of the time the ground I'm hunting is moderately to heavily mineralized anyway.
Anyway, I guess what I'm trying to say is that imaging is not everything. I have found coins underneath aluminum soda cans. Older coins, too. Even silver. One time I dug up an old mason jar that was full of Buffalo nickels. These are targets that I probably wouldn't have dug had I been using imaging. A double"D" searchcoil will pick up a fine chain better than a concentric search coil, too.
I dig every thing(for the most part)unless I'm feeling particulary lazy or hurtin'
These GTI's are great machines even when imaging is not used. Just my two cents worth.
Best of luck to ya!
Happy Hunting!

Best of luck to ya!Happy Hunting!Although I don't own a GTI1500 I believe you will have to decide what conductivity
range and size you want to dig and not stray from that Nigel. I mean dig every signal
that meets that conductivity and size if you are after gold jewelry with your GTI1500.
I may be wrong but I believe a lot of trash is also going to be in that same range.
If digging 18 ring pulls seems like a lot you may want to rethink about being a gold
jewelry hunter as that sure isn't very many at all. A lot of trash will size like a ring I
am thinking. Digging all of a certain size may cut down the odds of some trash
although some gold jewelry will surely be missed in the process. There is no perfect
detector that I know of for hunting gold jewelry. You just have to play the odds.
You have, by most accounts, one of the best coin detectors on the market.
Should do good on gold jewelry too but trash just goes with the territory.
Best of luck in tracking down that elusive gold jewelry Nigel ! Gene

Hi,thanks for your advise and everyone else who has commented.I didn't mean iron pot.i meant a pottery pot.I was just interested in what kind of signal you would see on the gti 1500 if you went over a pot of gold coins with the detector.Not that i ever will ,i suppose.I have had the gti for about a month now and am doing OK.I know i have alot of practicing ahead of me to be fully able to use this machine to its potential.This doesn't bother me as I'm hooked on detecting.Anyway thanks for your advise,i will carry on and on and on till me and the machine become one.cheers NIGEL.
