It's only an air test, but still gives some nice technical information.....

:nerd:Someone Requested An Infinium Mono Coil Size Comparison Using A US Nickel....It's Done:nerd:

Hey cool.I was thinking about the 14" mono but that can come later.The 8" sure air test great.
Hey do have any small lead shot,fishing weights?
Maybe flatten it so its more nugget shape
What I do-take a string then tape a gram size on one end and a .5 gram size on the other end.
Gives me instant test sample,make sure its long enough so you dont hit both.Then you can bury string and find your test nugget again.I dont carry any gold out detecting (never take your gold to the river-bad luck)-so I carry my lead nuggets until i find the real deal.

Something to remember when making test targets out of lead is that when you hammer or compress the lead it will produse a weaker signal from the Infinium than a natural un altered piece of lead of the same weight and size, so when you are checking the sensitivity of the infinium with lead to find out what size gold it will respond to the lead must not be a bit that has been hammered or squeezed. The atomic structure becomes fractured and makes the lead less conductive to eddy currents.
Yeah I think this post is to give you a idea on what to expect using a mono coil and NOT a DD coil.
The DD coil is stock so its pretty easy for anyone with a infinum to see what it does.
Mono coil composed of one single coil, not two coils, aranged side by side to make a DD pattern.
The DD coils have better coverage and handle mineralzied ground better.The mono coils go deeper but require overlapped sweeps and do not handle mineralized gorund as well.
As far as the lead thing goes.I think flatting it would make it react more like gold?? Dont you think-im not sure but lead is more conductive then gold?
Would this not make the flattened lead react mroe like gold-or not?
I guess one could melt/mold them into nugget shapes.I just think the nickle test is not a fair comarsion to a real gold nugget or is it????

I was just pointing out the change in conductivity (eddy current) of lead if it is hammered or squashed in any way.
My Infinium responds more strongly to gold than lead.
PI metal detectors normally only have one winding for transmitt and receive (electronic nature of the beast). The Infinium has two coils in the monos in order to help in the iron ID feature, among other things. PI DD coils are not true DDs as used with VLF detectors and are by nature (in PI config) much less sensitive than an equal overall sized mono.
Metal Conductivity list. (silver best) .

Thanks for the list.Great information.Thanks for the information about the DD coils-I forgot that PI are much differant than VLF.I also forgot that the Infinium is much differant than other Pi detectors.
Hey so does the discrimanation work on both DD and MONO. I heard you lose discrimanation with the MONO coils.
I am debating between the 8" and 14".Arghaa I know I want both but money is tight and I am waiting on tax return for new VLF.
I think the 14" mono is more sensative than the little 3x7 DD and Goes the deepest.It may be bothered by hot rocks more-my VLF machines arch enemy.
Alot of real conductive iron pyrite.I know the infinium ignores them with the DD hoping the same is true with mono-guess I could GB over a iron pyrite rock .
I want depth more than anything and been waiting for a 18" coil-but Im sure thats not ever going to happen.
Been hoping a outside company would start producing them-there is the demand for them.

With the Infinium both the monos and DDs discriminate. I do not know about the Minelabs.
The Infinium monos will handle very bad ground, The DDs are ok but not as sensitive.
The 3 x 7 will respond to the same minimum size nug as the DD And Monos but at much less depth.
use the small DDs for tight places and for scanning bed rock cracks.
The 10 x 14 DD is not too flash on small gold but good for deep big stuff in tough ground.
I find the mono's to be capable of doing an excellent job in all ground conditions and are a tad more sensitive and give a smoother response than the DDs although I find the mid size DD to be very nice on salt beaches
If I had to choose one coil it would probably be the 8 inch mono; It is slightly more sensitive to small gold than and goes almost as deep as the 10 x 14 on big deep stuff, it is waterproof and does as good job over bed rock and rocky ground. The 10 x 14 mono is great and covers a lot more ground in one sweep but is only marginally better than the 8 inch mono for depth on deep large targets.
A lot of people like the big mono but I prefer the 8 inch because it is light, waterproof with good sensitivity and penetrates deep in tough ground.
Just my opinion

Thanks dude,Im getting the 8"-Im really poor bugger at the moment and can get one for $99.00, thats in my price range.
I think im sticking with the Infinium for nugget's! Been wanting a VLF for smaller gold but I really hate all the problems you get in the rocky mountains with vlf machine's.
It also seems the 8" be great for beach hunitng-water hunting-something I want to do more this year-I know where there's a real expensive platnium ring.

You cannot go wrong with the 8 inch.
Good luck with the plat ring.

No, Just the 10 x 14 DD and the Mono's.
The small DDs are wading only. I have used mine in waist deep water but they are not designed for that kind of water pressure.
