Problems in Tesoro Lobo Super Traq

[Ruben2000]

Hello friends, I have bought a Tesoro Lobo Super Traq detector and I have seen that it does not have a good detection range; I would like to know if your scope is correct. I have tested it in the air with a 25.5 m coin. in diameter with a weight of 7.32 grams and detects it at 20 centimeters. Then I tested it with a 1N4148 diode, it detects it at 1 inch. I made both measurements in all metal mode and the other selector in normal mode.
I would like to know your answers, if that is acceptable for this detector or do you need to make some adjustments to the PCB.
My Tesoro Lobo Super Traq is gray, I didn't know that color existed.
Here I send some photos.

I failed to mention that I also made both measurements with the sensitivity selector 10.

You cannot expect great "depths" from that type of detector.
In general, no Tesoro is "deep".
And especially the nugget hunter type of detector will not be deep.
And with such a coil.
I think that is a perfectly fine result and that there is nothing wrong with that detector.
Maybe you would get a few centimeters in depth with a diy coil, DD type, of larger dimensions.
But the question is whether it is worth the effort.
It is a detector intended for very small objects.
A crystal diode is not a valid target.

do you need to make some adjustments to the PCB.

no data, not given. yup, i did believe after Tesoro crash somebody will get their whole archive, but not. no issue.
all died. your way probably is to do new coil with more great tuning.
so nice board, SMD made, microchip used (sic) and such poor result... just 20cm depth. a blood, a sweat and the tears

[ivconic]

Don't scoff, there's a reason why that's the case.
And you know very well why that is.
In some types of searches for some types of targets; great "depths" are counterproductive.

Make sure Soil is set to Normal, Mode is All-Metal, and you adjust for a slight threshold. It should detect a 25mm coin a bit deeper than 20cm. I sold my LST so I cannot offer a comparison. The early LSTs had brown plastic and an anodized gold rod, the later ones were all-gray, no doubt to reduce cost.

OK, thank you very much Ivcónico for your opinion, I have tested those measurements with the 5"x10" coil.
The person who sold me the detector also gave it to me with the 10.5"x12" coil. I will use that coil for larger objects.
My disappointment is that I wanted to use it to detect nuggets but the depth is not that good. I have seen on YouTube that it can detect 0.33 gram gold dust.

Hello KT, thank you also for your opinion and thank you also for sharing your files.
I think the same; This detector's cost is much higher here in my country than an XP ORX. So much investment in SMD components for little range.
I see that you like to collect images of detectors. Here I share some of my Super Traq Lobo Treasure Detector.

Thanks Carl, I've done exactly what you say and I'm only getting what I mentioned above.

... This detector's cost is much higher here in my country than an XP ORX. ...

I've had a Deus 1 since 2012. It's certainly a more complete and better machine than the ORX.
It never occurred to me to try how the detector will detect the diode... but I'm almost 100% sure that Dues won't detect it at all even if I "rub" the diode from the surface of the coil.
So that result of yours with the diode is phenomenal!
And it just proves that my point is correct.
It is a detector specialized for very small targets.
And from that point of view, it is not "shallow" at all, on the contrary.
20cm on a coin can be "bad" but also a phenomenal result. It depends on the coin. Alloy, type, etc...
I'm getting more and more "annoyed" about this and even though I hate looking for Deus now... you're going to make me want to test how it behaves on a diode!
Arrgrghhhh!

[Ruben2000]

I found this video and see that my tests are acceptable according to the video. My currency is similar to the third objective.

I have always tested the detectors I have made thanks to Geotech with a glass diode. I tasted them so I could look for nuggets; I have nothing that is gold to prove.

[ivconic]

Huh!
Watch the whole video till the end...
Three things;
1) Your method is correct and makes sense (now that I tried it; I see that you are right),
2) It is obvious that I greatly underestimated my favorite Deus!
3) The 1N4148 diode is really detectable... first of all I think it's the wire legs and their length and not just the body of the diode.

But as you can see in the video; Deus didn't make too much of a name either.
In most cases it's audio&VDI response that I would interpret as "garbage" in the real world and wouldn't dig it.

[kt315]

please do not compare Tesoro and Deus. last one has preamplifer in the coil and full schematic of end amplifier also in the coil.
digitally processed signal TX is translating in the main box. NO NOISE, SHORTEST SIGNALS WIRES, MAXIMALLY POSSIBLE DEPTH FOR VLF.

ABSOLUTELY DIFFERENT THINGS!

thank you lots. i will put the pics in the Archive.
