And Bugs.... Although you say "Then there is your stating "staggering differences between detectors"
To expose your revenge lie for being sacked as a dealer I contacted a number of owners and invited them to the test patch to test/compare.
All of the 7 detectors tested produced identical results over the 2 test targets.
Those present can confirm this."
(Yep I was there!)
There were 5 detectors tested, plus a faulty one, with "dry solder joints" you said, owned by Rom S. (Rom still has issues with his machine despite numerous returns/repairs and you saying there is nothing wrong! . Shane T sent his box to Brian 6+ months ago and has been without a machine, and no idea when he'll see a return.)
While performances were similar and close on the surface coins place down (air test), and all machines were tested at factory reset settings. Later field use and results were far from, and were worse after the next round of updates after the introduction of the PL4.
Do you remember the great results achieved with my 20" Spiral Xcoil on essentially "factory reset" that surprised even you!
How disappointed do you think I was less than 12 months later, being unable to come close, using the hottest and deepest settings usable!
) And like most is enjoying the giggle.
