Test Nuggets

[clodmac]

G'day Guys I'm trying to find out where I can get a test nugget or 2 that weigh 0.0025 of a gram , which is 1/400th of a gram . There is a guy on youtube from Ballarat that uses a nugget that small to test his mods regularly . If anyone has a couple that size I would be interested in buying a couple to test on my PI machines .

Try Ebay or Gumtree.

G'day Clodmac.

I would be very surprised if he is using a piece that small. I could be wrong because I haven't seen Woody's videos. A piece 0.025 gram would be more realistic, although I have seen a piece of gold much smaller than 0.025 that was picked up with a GPX6000.

I personally use a piece that is 0.06 gram in weight to check my 7000 after tuning. The smallest piece I have found with the 7000 is 0.026 gram.

I would suggest using a piece of lead instead. You will need a piece of lead that weighs about 0.0015 gram to get the equivalent gold size.

Regards Axtyr.

Agree with Axtyr, unlikely to be .0025 and be getting hits with a PI.

Also, do you really want to be finding that stuff? Hard enough to locate a .01 in the scoop.

I’ve no idea what the 2 bits are in my pic but I would doubt they would register on my scales. Maybe .01 or less. Both found with a PI and if you’re pinging this stuff with your PI I would say your machine is well dialled in for small bits. As small as I want to be finding anyway.

Rather than wasting time and money on eBay, if you PM me your mailing address I’ll send them to you no charge. The stamp will probably cost more than the gold

Cheers, NE.

The metal thing is the end of a small paper clip for size reference.

Herman used a o.6 g buried at 150mm to set up my 4500. I hot glue my test bits to a bottle top and have 300mm of braid line to find where it is buried.

Agree - get a 1grain (0.06g) 24kt flat rectangular ingot from ebay or similar.

Cut it in half with a sharp scalpel & cut 1 of the halves in half repeatedly until you cant see it.
0.06
0.03
0.015
0.0075
0.0038
0.0019

Also I too really cant believe that you can find 0.0025g with a PI

G'day Axtyr , the guy from Ballarat claims that the nugget is 0.0025 in a number of his vids , perhaps his scales don't work or he is not very good with numbers , the level of sensitivity he can create with his mods is astonishing . He can get a GP Extreme to match the 6000 using very low gain and in Normal and Cancel mode with an old DD coil in his workshop . Even with his other test nuggets allegedly 0.05 and 0.1 .

The test nuggets I use at the moment are about .03 or so each , in the pic below

Cheers Clod

G'day XLOOX I have a 0.03 bit I found on Sunday I could probably flatten that out and cut it up if I can't get a natural bit that small .
I have some doubts about getting a 0.0025 with my PI machines as well , need 1 to verify it though .

Do you think you would hear a nugget that size with the equinox ?

G'day NE

I'm not really interested in finding 400 bits to the gram , just wondering if it's possible with a PI hence the need to get a nugget to test with my PI machines .

As you say it's hard enough finding 0.01 or smaller in the scoop , dunno how many times I have tipped out little bits and had to go through the dirt again to get it .

The point of all this is to find out if the Ballarat guys mods are as good as he demonstrates in the vids , the sensitivity the demonstrates is amazing given he sets the detectors in cancel , uses standard minelab coils and blows all other std minelab detectors into the dust .

If his machines work as claimed there would be plenty of 0.1 and bigger bits that are out of reach of std machines including 6 and 7000 .

Thank you for the offer of the test nuggets , I have a mate who is a small gold wizard that uses a 6000 that has a few little ones he will part with , might cost me a couple of packets of bickies to share with a cuppa . he has a few like those in the pic below that are similiar is size to what you find , these few average 0.012

Cheers Clod
