Red Heat XD-17

[eduardo1979]

Hello! There is someone who could help with a scheme electronics of the detector Red Heat XD-17? Thank you very much!

do not be so nerve... there have been people who asked kinda you... get your head up... find by eyes a word Search... use...

[Op04]

I've been searching for this xd17, does anyone has schematic / PCB for this?

[kt315]

good searched?

[Op04]

I already have schematic from another source, not from here (still not found here) need PCB for that, still no luck

It would be a good start if you posted the schematic that you already have. Especially since it doesn't exist here.
You have to give something to receive something, and maybe someone will recognize it.

Thank you for your attention Mr.Qiaozhi.
I still haven't got permission from the owner of this files, but he put this on public appearance. So I guessing he will not mad at me
This is all I got.

Thanks. That schematic must be on the Geotech forum somewhere, as I already have a copy in my archive.
However, there is no associated PCB layout.

The problem with these Red Heat detectors is that they were all custom made by the designer Vic Fiveash, who passed away in 2007. The PCBs were not made from a set of Gerber files, but were etched by Vic using nasty chemicals. As a consequence there are many variations around.

As an example I've attached some photos of an XD-17 which I repaired for someone. The detector did not match the schematic exactly.

That's really cool!! Thank you so much, I really appreciate it. From the sch, I think there are wrong connected between last section of comparator, I put comparison between xd and lobo. I still not much time to trace with dxp, this will be saving for future project, unless someone here trace it.

Regards

Legendary and a prized detector in the UK, in the day.... The builder past away a number of years ago and he took everything with him.


Red Heat Metal Detector- made by the world famous technician Vic Fiveash. Every detector was custom built to perfection by him. Red Heat first started manufacturing metal detectors over 20 years ago in Great Britain. Their first detectors were designed to go thru the Thames foreshore area. This site was not for newcomers, only the most experienced detectorist would even attempt it because of the thousands of years of trash, coke, and iron. When the Red Heat detector functioned so well in such contamination they knew these machines were special. Very Rare Metal Detector and extremely hard to come by. One of the best see thru iron machines ever made. Vic Fiveash passed away in 2007. .

Looking at the diagram, this HEAT XD-17 looks like it is a Tesoro metal detector.

That was my conclusion as well, that all Red Heat detectors are derivatives of Tesoro designs.
The claimed ability of being able to "see through iron" is a myth.

Why the name "red heat" ?
Maybe because it's hot, and hot things tend to glow red? And while we're at it , let's throw in something flashy, like xd-17, gives it that NASA scientists "feel". Oh Lord, the names people can come up with. Sounds more like a carnival street band in the middle of summer.
Definitely a tesoro clone.
At least Qiaozhi's voodoo detector hints at the psuedo( superstitious) belief of traditional discrimination in a classic pi detector.
Hence the name voodoo. So there's some merit there, the name hints at the intention of the inventor to achieve some measure of rudimentary discrimination, by actually walking the talk. And not by invoking such ridiculous incantations for seeing through iron( red heat wave technology). Now that's voodoo!

So if you want to make red heat detector, just make TGSL instead, and you can call it the red hot chili peppers xd- 18.

By the way, " seeing through iron " is not synonymous with iron separation. The latter being a well known term in metal detector jargon. Then there's masking, which is yet another term bandied about with some amount of " confusement". (Picture the thicket of the forest.)
But literally seeing through iron, I suspect would require some gamma rays, or perhaps a Haitian specialist.

Good idea to have a table of definitions. Or something akin to a glossary of terms.

Off-topic, I know, sorry:
The "iron see-through" label was one that usually got applied to VLF's with high operating frequency, such as the 100 kHz Compass range, like the Yukon. The idea was the high frequency only penetrated iron items to a tiny depth ( ferromagnetic materials have very small skin depths, and at 100K it's really small ) so the iron targets didn't in turn create a strong magnetic field of their own, and they didn't distort the detectors field in the ground so much, thus allowing the possibility of finding non-ferrous items nearby - items that would be hidden/masked by using a more conventional lower freq VLF.
