gold detecting , smallest speck and largest lump whats yours ?????

[aussiefarmer]

Hey every body I just thought this would be good food for thought , so I am asking what is the smallest your detector has recovered and the largest , Maybe list the detector used and depth, maybe even soil type, just purely out of interest

I am on the verge of getting something to swing so I thought this may just be useful brain food ,especially the smallest as I seem to have a knack with the sluice of getting tiny gold

I've got a few that don't even register on scales. Was my SDC, pretty close to the surface, maybe 1cm deep. Ground was quite Shaley and quite mineralised.

that's great to know its the sdc that im hoping to swing , how many decimal points do the scales go eg. 0.00 ,

My smallest - 0.01gr; (Mullock heap, Paddys Ranges, GPX5000, 12x7 nugget finder near 3" deep, I also got a 0.02gr in the same hole very close to the 0.01)

My Largest - I haven't found my largest yet

They were 0.00 scales AF. SDC is a great machine, extremely sensitive and very easy to use. Though you'can get a GPX4500 probably cheaper than an SDC these days. 4500 is not quite as sensitive but will beat the SDC on depth with bigger gold.

Have a few that don't register on the scales found with 8" and 11" monos on a 4500. Biggest to date is 3.33g with the evolution 17x13" smallest so far with that coil is 0.11

 

[tryhard1968]

Have found just over 20grams mainly with the SDC and 4500 with 12x7NF and my biggest being a 38gram slug with the 4500 and 15x12 ML Commander.

In Tassie, with an SDC 2300 and a 0.01 g scale:

Smallest = too small to register
Largest = either a 3 g nugget or a specimen with about 4 g of gold in it.

 

[SteelPat]

Smallest that registered was .02gm @ about 3"
Largest is 15.5gm @ about 6 - 8"

All using GPZ7000

SDC .46g 4"down

I'm not sure I like hearing about the biggest , got some serious nugget envy going on. Love the smallest though. My biggest is only 1 .5 g but got lots of the smallest. My favorite the misuses gold shot. Doesn't registar but looks cool in the fry pan.

 

[aussiefarmer]

this is great , will small bits signal if there is a lot of micro alluvial gold or do they need to be sitting on there own ? if that makes sense so somewhere I would normally sluice for flour gold would it still define the 0.02 bits ?

 

[Bjay]

No idea really but I would think that it would have to be really concentrated in a very small area to get any sort of response

 

[aussiefarmer]

my question was more will it signal a 0.02 g piece if there's fine gold about or would it get distracted lol :lol:
while I am asking silly questions would it pay to use it until I found a piece and then test pan or sluice that area ?

That's a really interesting question. I know that with my detector, after going over a large piece of metal, it will certainly overload for a bit. It takes a second or two to be able to detect another separate piece of metal. The question is what size a piece of metal has a noticeable effect on the detector's ability to detect another...

I can tell you that in practice, if I'm detecting in creeks or rivers and I pick up a nugget, they're almost always in crevices, and those crevices are well worth panning. About a year ago I was detecting a small creek near Corinna, in NW Tasmania, and I picked up a signal under a cobble bank. The signal was a little 0.2 g nugget that was sitting in a crack that was hidden by the cobbles covering it. I then panned the whole contents of the crack and got about 2 g of gold off 3 pan's worth of wash. Most of it was fairly fine, but there were several detectable-size pieces that were just too deep.

One of the smaller ones at 0.00 inches

great pic timau its shinning like somebody dropped it

I know I keep taking my own post off topic but does the ground moisture have any effect ? as in is wet ground more conductive to signal or is dry ground more effective or does it have zero difference ?
