In my opinion, the original PD Alonso must also be unstable. In the films that you and Morgan recorded in Portugal.. all the films are only a few seconds and at most a minute... the PD is being processed and explored... there is no film that is being processed and explored for 10 minutes.
Yes, I have very precise measuring equipment.
The use of high-beta transistors in the form of Darlingtons is one of the reasons for the PD's instability.

My PD is very stable. I must turn it on and wait for 1 minute, after it i can adjust it and go.
At Portugal our purpose was to show that PD works and can catch the phenomeno. Our interest was not to show how much good was the PD.
The main problem was that it needed very critical adjustment.

Morgan said that the PD can detect a coin from 30 cm. For an Omega coil with a diameter of 10 cm, this is an unusual detection distance!!! Did you test in Portugal to see from what distance it could detect a coin?

I think near to 15 cm, maybe 20 cm max. So does mine pd

The long range detection is a very strange thing. Although i have detect many objects with many lrl i can't say with sure "take this lrl and it will work 100%"

My Alonso circuit on the workbench is very stable.
The instability occurs during the search. The place where it becomes unstable is where the metal is buried.

Yes.
I have fine-tuned the Omega and it detects coins at best from 20 cm. No more.

Yes, I have built several long-range circuits.
They don't always work 100%.
Physical and environmental conditions and weather conditions are important.
