I wonder if Coiltek and Nugget Finder will extend the new lines to larger coils, such as 19". Maybe they are focusing on the smaller coils to suit the Algo and the modded GPXs. XCoils seems to have produced larger coils using a similar technology without making a prohibitively heavy coil.

Nugget Finder site under "Evolution" says "MORE INFORMATION COMING SOON" https://www.nuggetfinder.com.au/about-1 Makes me think they only paused production and did not end the product line. Otherwise why not say something like "Evolution Line Has Been Discontinued"?

I just bought an Algo through this dealer and received it yesterday. This is a legit dealer.

Apparently, US Mint has been ordered to discontinue minting one cent coins. According to the mint it costs 3.7 cents to mint and distribute a one cent coin, resulting in a loss of 85 million last year. Canada, New Zealand, Australia, and the Netherlands, got rid of their pennies a long time ago. It is about time the US follows suit! Pennies are so worthless kids do not even bother picking them up. In the past, the zinc lobby has prevented Congress from passing legislation to end the one cent coin. We will still be finding those crusty, corroded, pieces of junk metal for a long time, but at least the supply will be cut off. Good riddance zincoln cent!

Steve G could probably make a shaft that is compatible with the GPX lower rods, which are non-carbon. Many of you GPX-5000 users probably have several of them, I know I do.

Looks like bornite, which is an iron-copper sulfide.

I loved the Uniprobe back in the day. I bought it from Steve. Was very precise. The object was always directly beneath the probe and it had pretty good depth. The problem that I had was the connections/wires were constantly breaking. I don't know how many times I sent it to NY for repairs. I still have it somewhere.

Kudos Jeff for putting this information out there, especially knowing that you opened yourself up to all of the naysayers who claim that it cannot be done. I have never seen you post anything designed to brag or to boost your ego, and I have no doubt you are able to do what you say you can do. I have been doing the tests that you describe with a nickel a gold ring and a pull tab and I think I know what you are talking about. My brain tends to convert sounds into pictures. To me, the full pull tab sounds like a porous piece of fabric, while the gold ring is a halo with glowing white edges. Now being able to hear this in an air test is a different matter from hearing this in the ground.

No regrets here! I have found silver in parks which have been pounded by the 800 and other machines. One thing that I noticed was, when I first got the Equinox I got signals that were obvious "dig me" signals that turned out to be silver. On the Manticore the remaining signals have been more iffy but I was still able to squeeze out a few more finds from the same places. Yes, I have dug a bit more iron, but it has been worth it for me. I just tried the M8 a couple of days ago and was generally pleased. Nice and light, great separation. As others have mentioned, it does up-average more than the M11. I got a solid signal in the 90s that turned out to be a wheat at 6 inches. As long as you recognize this, I guess it does not matter too much. The target trace is useful, but I must admit that I do not feel like I have mastered it yet. More information is always better in my book. As far a the Deus 2, I have not tried it, but the stuck pig squeals that come out of the XP machines have never appealed to me. Just my opinion of course.

Looks very similar to my plot Lync. Good to have it confirmed using a different set of items and different detectors. Have you tried plotting the line to your results using the equation that I provided?

I used the coins and nuggets in the photo plus a bunch of gold jewelry. The very lowest value was a 14K post earring. A few of the coins in the photo (the large cent, reales, and 2-cent coin) were not used in the graph because I did not get a VDI on the 800 before I sold it.

Strick, My interpretation of the graph is that the numbers were expanded in the middle of the range, but not so much on the high and low ends. It you approximate a straight line through the highest three points, the slope looks to be less than 1, meaning that the Equinox actually has slightly more resolution in this area (i.e. more numbers between a US quarter and a silver dollar). Near the middle of the curve, the slope is much higher than 1, indicating that the MC has an expanded range in this area. I think in this area you are correct, that the numbers are approximately doubled (e.g. for a nickel this is true, 12-13 for EQI vs 26-27 for the MC). I would guess that this was intentional. There is no real benefit from expanding the range between a quarter and a dollar, but some possible benefit in the middle of the range where pull tabs and gold jewelry are present (but this is debatable of course).

No, unfortunately my brain is not that powerful. I used the R statistical program to fit a sigmoidal curve using a least squares regression. I use R for work, so I had everything handy.

I put this together back when I first got the MC, but did not think it would be of interest to anyone but myself. However, since the topic came up I thought I would post it.

Exactly why I am interested. I have a 5000 with lots of coils and no desire to drop several thousand for a ML PI gold detector.
