If youn are working towards your suggestion that a $500 patent is worth nothing unless you have $100000 to line lawyers pockets to defend it then I have a different reply.
When confronted by a bully you have two choices.
1: You run away and stay away.
2: You run away and find your own bigger bully.

BW,
The Bully Mythology is a convenient scapegoat when things ain't going right. Sure, the patent can pump up the ego and rally the troops, but it ain't getting the job done. I can show my boss lots of patents and lots of photos, but what he wants to see are products. If all I got are patents and photos, I'd better look for another job.
No, the answer to questions #134 and #135 are the same: the patent, the photos, the schematic, the claims, are all bragging points. And if all you want to do is brag, then you're loaded for bear!
While there's no question that Doug's MO is bragging (and just a coat-tail braggart at that), I suspect you'd like to go beyond that. Read post #76. Read it again. There's a lot to digest, and some of it don't go down easily. Forget about the Bully Mythology. Ditch the forum nonsense. Get to work, focus on what matters, finish it. Or not. Let it go. But don't just sit there and be a braggart, all that does is fuel the antics on Finders, and makes you look bad.
I'm rooting for you, but right now it ain't looking good.

Regarding the video showing the QED being ground balanced over hot ground - I notice that the bullet generates an audio signal as it enters the coil and also as it leaves. Is this a side effect of the ground balancing? Does the same thing happen for a U.S. nickel?

More patent details
I did a search and found some more detailed information on the QED patent (with diagrams).

Have a look at the beer can video, it's a rising pitch and only overshoots if the signal is gross.
Ferrous targets tend to produce a double tone, rise dip rise. It's a form of discrimination but cannot be relied on as very rusty iron can produce a single rising tone.

While it may be distracting you get used to it. It actually helps with tiny targets as the overshoot is louder and longer than the dipping tone.

From the beer can video it is clear that low and high conductive targets react differently. Although this may help with small gold targets, I would think that pinpointing might be a bit of a problem.

Keep up the good work.
By the way, in answer to your questions concerning the best way to sell the QED, I would suggest offering a full kit of electronic parts. Users can then supply their own enclosures, stems and coils. A partial kit will be a nightmare to support - you can ask Gary (Chemelec) about that - and the idea of a fully assembled and tested detector has already been answered by Carl in his 5th commandment ... unless you want to be potting coils all day, instead of working on QED2.

In the good old days, many electronic manufacturers supplied a schematic for their products to enable repairs. In those same good old days retailers had a markup of 33% on the cost price. These days it's charge whatever the market will bear. I am only interested in one thing, producing a competitive detector at a realistic price because the gold and other treasures in the ground belong to the people.
