My detecting mate had one of those older FG body coils except it was a 10" Round and he believed it was the best mono coil that he ever owned.

Did BC have anything to do with the Gpx6000 as it not mentioned on the chart?

As the gold price continues to rise & rise that may justify the cost of next Minelab PI, in their thinking, if capable of outperforming all other manufactures at the time of its release.

Sorry to hear that as it was not the case with the QED that I used. Anyway, I did not mean to take the discussion away from the Algoforce.

One good thing that the QED had through the use of its MGB adjustment to complete a Ground Balance was to give a figure / number reading on its screen for the type of ground, that being the higher the figure / number reading the more mineralised the ground.

Yes, it was a 50c cupro-nickel coin and what I found interesting was this coin recorded a similar test result to that 4" x 2" x 3/8" Aluminium Block that I posted a pic of it in that comparison Video thread discussion. Therefore, I expect one could use this 50c coin to replicate a sizable piece of gold. Also, from my results then this 50c coin produced a few inches more than Chet's results with the USA $50 dollar 99% gold coin, when using the same three standard coils that come with the 6000. I think both coins are somewhat similar in dimensions.?

I have compared my 11 coil to my friend with the NF12x7 coil on my tiniest 0.03 gram piece and both produced the same result. However, the 12x7 will poke into tight places that the 11 cannot go or reach too.

Yes, as the tiniest piece that I have detected with the 17x13 coil on the 6000 has been a 0.08 gram and with the 11 coil a 0.03 gram.

Yes, no doubt the DOD coils are impressive and more so the higher the ground is mineralised.

A result, I have between the GPZ7000 in Difficult/ General with its 14 coil to the GPX6000 in Difficult / Auto + with the 17x13 coil on an Aussie 50c coin, was the same.

I expect why this block of Aluminium was created to mimic a larger Nugget of Gold for testing at inground test sites down your way.

I purchased my 6000 three months after its release date and have had no issues with the 11 coil. So, is there a date period that covers those older early built 11 coils that you speak of ? Also is there a date period for those early 17x13 coils that are not as good as the newer 17x13 coils, that you speak of as well ?

I have had NO such issues at all as Aureous has mentioned when I have been using my 17x13 coil including it producing extra depth over the 11 coil depending on the size of the nugget. No problems running high Manual or Auto settings from my experience. NF definitely produce great robust coils which can handle more rough use than the light weight 6000 coils.

Wonder how long before he performs all the tests as he explained in this video using all three detectors with various coil combinations?
