Coiltek or Nuggetfinder coils in high mineralized ground

which of these 2 brands of coil works best in high mineralized ground you can enter my poll if you want to.

many thanks.

I'm amazed to see such a large disparity between coils. I would say there would be hardly any difference in the ability of any of these coils to handle hot ground, it really depends on the detector and the operator. I have used all three makes of coils and found little difference in their ability to handle hot ground myself although I have seen information posted here that suggests some NF coils may have a problem on extremely mineralised ground.

Cheers, Jim

Most people I know reckon NF are great in Highly mineralized ground. Have not heard any one complain about one yet. Sometimes coils are like cars, you have your holden or ford fans and they stick by them. But really it does not matter if you are a NF, Minelab or a one eyed Coiltek coil fan because as you stated Jim it is about operator. A good one can use any and do well. There is one guy in our club that uses an old, battered minelab coil but goes slow, low and is patient and gets gold often when others don't.

I agree with Granites reply to all this.

I find this poll interesting. When we used our nugget finder coil in WA on what we thought was highly mineralised ground it was so so sensitive. Any minor thing made it complain / become noisy. When we switched to the original 11" mono comander that handled the ground much better. Just our findings. On another note, the nuggetfinder coil I believe is a much more sensitive coil than the comander coil we have. And to elaborate, we were using an 18" round nuggetfinder so that could have a bearing against the 11" comander.

All three main coil manufacturers are pretty much on par with one another in terms of coil handling capabilities and performance on a variety of soil compositions,the main differences being in weight factor. Jim couldn't have explained it any clearer."It really depends on the detector and the experience of the operator using it".

Wouldn't a coil that is highly reactive in mineralized ground point out that it has higher sensitivity, so it would be the best coil ?

that would make the worst coil the best coil.........unless of course you were looking for the best coil to reduce sensitivity which would of course be the worst coil not the best coil.... I hope I have made myself clear

so to sum up....

In relation to Highly mineralized ground.....

1. The best coil is the worst coil

2. The worst coil is the best coil

Harb, your post is the best post, so therefore it is the ........

I have used all the above mentioned coil and have to agree with granite and kon cheers mike

We all have our preference, my wife likes coiltec. After destroying 3 NF 14" elip coils with hard work and rough use, the only coil that I could get to replace it was a Coiltec 14" elip. The wife says her is the best coil she has had, but I still would prefer to swap my 14" coiltec with my last NF. In fact I went for a 14" round NF when I got back home.

Ford Vs Holden.....Toyota Vs Nissan,everyone has different opinions.
Remember the old days,when all we had was either the stock Minelab Coils or Coilteks?
Most chose Coiltek.
Whenever someone has a good find,everyone thinks`GOT TO GET ONE OF THOSE COILS`,so they think they will be backing a winner. 9 outa 10 times the nugget or patch could have been found with any Coil and with even older Minelabs. You just have to walk over it,and dig it!
No matter how good your coil is,poor detecting techniques/mindset or a total misunderstanding of the opperation/limitations of your detector wont help you find more Gold.

Well spoken Gus.Bravo.So easy to find fault with everything and every one,except ourselves.

Hi Tim,

I cannot really cast a vote, as I have all Nugget Finder coils. I don't use Coiltec coils because they are noisy in certain situations and they are heavier than the equivalent NF. I don't use the excellent Minelab coils, because they are too heavy for me to swing comfortably.

When I detect, I detect with the coil right on the ground. I used to have both the 14" and 18" ellip. Coiltek Commander coils, but I had to sell them because of the noise made by them when I contacted rocks or vegetation. The 12" elliptical NF is the quietest coil I have used and because of that, it is my favourite.

I know Coiltec received many many complaints about this and perhaps they have fixed the problem in the newly released coils with the Lizt wire - I hope so, because they are good people.

Nugget Finder any time, I have sold all my other coils.

Pardon the ignorance, but what is meant by a "quiet coil" ??

Is it just the noise it makes when you whack it against a rock???

So far everybody has given an opinion on their experiences with the brands that they have used, however, to make a valid comparison I would expect that the tests be done under identical conditions. The coils should be the same size, used at the same location on the same target, with the same detector and the settings optimised for that coil, otherwise you'd be comparing peas with carrots (re Forrest Gump). Perhaps a few members with different coils could get together one day and do a controlled test? I for one would be interested in the results.

Hi Ringpull that is a very good idea you have come up with that should sought which is the best.
Cheers mike.

Take two branded 14x9 coils for testing purposes, how are you going to know which coil is slightly off Q?? Electrically challenging for the human ear to detect, and if there was a noticeable difference to the point of our ear picking it up...obviously a faulty coil.? Branding one coil not as good as the other by those testing it, and convincing themselves brand X is the better coil.

Since both leading after market brands are using the litz wire in there coil ranges, why not have the manufacturer display one cut in half to reveal how each brand is potted/constructed.?
I find that would be more exiting to see than testing wire against wire.??

Here is a cross cut of a wrecked NF 14x9" Elip Mono Litzs Wire. The black is the shielding and is about 2 cm across.

Was kinda hoping to see a cross sectional shot showing how it sits in the casing...similar to my repairable rite off of the early fiberglass 16" NF SL ...yet thats an interesting show of the windings geof_junk thx for the shot.

To participate in an experiment like this would require the participant to use all three brands of the same size on the same target undug in highly mineralized ground, I myself could not enter this experiment. Can anyone else?

If both makers are using the same wire & have the same number of windings in equivalent size coils can't see there being much dif? I only have Minelab & Coiltek but both worked well in WA last 2 trips. One thing though My mate and I were given a couple of 6" coiltek monos to test at Echunga for the maker, one was definitely noisier than the other on both GP3500s we used. So the manufacturing process, batch of wire, teminations, packing or lack of etc could come in to play. Definitely would be intersted in seeing a blind test using the one machine with a variety of like for like coils on a target in it's native state.

Nugget finder are my choice
But others prefer coiltec
You can't go past the Minelab 11 inch mono
(but I don't own one still)
Most importantly it's the operator on the blunt end that makes the coil work how it's needed too
