What detector is Uniprobe?

[Malospelos]

Good morning friends, I wanted to ask if anyone knows which detector the new model Uniprobe probe has, as I have seen on YouTube the detector self-adjusts to the terrain.

It looks like a Pi polones or similar, which of the existing projects self-adjusts the terrain? So that it doesn't give a signal?

The photos of the pcb I remember, resembled Eric Foster's Gold Quest. I think the adjustment is the SAT and not GEB.

In the video he demos a later model, but these have not been produced for many years.

It's almost certainly the same circuitry as used in Headhunter PI which was designed by Eric. It even sounds the same. The "adjusts to terrain" is just the SAT.
