The measurement was made with a coil close to the antenna. I didn't want to open the detector because of the warranty

If you own this MD, can you please share more info, thank you

Look like a direct measurement across the coil ... note the volts per division is set to 500 volts ... those peaks are around 800 - 900 volts. So that means is a bipolar pulsing ... I get very similiar results from the CCPI with the grounded coil setup ( so the flybacks swing + / - as well as the current ).

They must have a big capacitance in there the flybacks are about 25 microseconds ... the TX current would be fairly high under these conditions.

Exactly my thoughts as well.

Fair enough ... may I ask what sort of coil you used and how close to the detector ?

Thanks.

Is this measuring the TX voltage or the TX current?

The PCB looks like built by a school student.
I don't have any personal experience with this detector. There is some positive feedback on the Bulgarian forums. I don't say the detector is not good. Just I didn't expect to see such PCB in a detector marketed as a "breakthrough" and at that price.

Tnaks on response, I have been watching all youtube videos about this MD, here is one
interesting video:

Here is one more:
https://youtu.be/sglhw9ERh3U?si=2s7nabHMAmCz22qB

There are actually around 25-30 videos about this MD on YouTube, mostly from the manufacturer itself.

It would be great if any forum members have practical experience with this MD and could share a few sentences about it.

I found a video demonstration that shows the good stuff. And the man who recorded it knows the subject very well.
I can't judge two things only: the realistic maximum depth (less important for me) and the masking problem that is not shown in the video.
Everything else is a pure ten.
Pay special attention to "vertical discrimination"!
It never occurred to me to try that with one of my detectors.
Conclusion; so far I have good impressions.

You didn't notice the problem with that device, that's why you're delighted

20:56 It praising the product well = a breakthrough in metal detector technology.

I thought about building a similar one, but I only saw only 1 benefit = reduction Tx current.



Here are my conclusions from the video.

15:57 HYBRID technology, a trade term similar to nano technology = sounds nice but means nothing.
17:58 Beer cap = all detectors show it as a color, only this one shows that it is iron. = I'm not convinced about this.
20:33 - 20:50 = does not discriminate coins.

About working frequency 2 kHz Tx is more like a Time Domain with 500 us period and 30 us bipolar pulses on 250 us delay between pulses
