TESORO GOLDEN SABRE

[Sacchetti]

ok noted with thanks
do you have you tgsl video i want to see

I do not have built TGSL but only Eldo relative to tessoro md.
Before and after I have built others md with technology PI, BFO and PLL.
Can be I will do also TGS in the future, in this case I will propose my video.

Paku, take attention: 2N2222 is NPN while 2N2907 is PNP.
The metal one can dissipate heat better.

You are artist - your detector is your canvas

My 8V regulator is L7808CV

Hi Sdesic,
take attention: this regulator is not a low dropout therefore if you use it then it is better to have a 12V battery.

what is big difference 2N2222, 2N2907 plastic one and metal one

Paku, take attention: 2N2222 is NPN while 2N2907 is PNP.

es that one of RX terminals must be connected to the shield?

RX end and TX end must be connected to shield..

The floor of sensitivity does not, during the rotation of the potentiometer nothing happens, and the detection depth does not exceed 19 cm for a currency in bronze.

@sdesic
if you have problem while nulling big coils make it so:
place the two coil so together that you have best null volltage (under 4mV is sometimes to low)
if you ahve best result you can achieve glue you coil all 2cm with hot glue
and set spacer between the gap
the fill coil shell half with epoxi and let it harden
next day measure the null voltage again
if it has drifted take a very small pieces of foil and place it one one side of the coil and set the null voltage again with this smal pieces of foil
if you found the best place glue it in and fill the rest of the epoxi


@paku
have you finished ?

not yet bro
i dont have time to make new coil
busy working this is just hobby for more experience
maybe i will do later

Hi everyone.. i been wondering if how many percent will be lost in the real ground compare in air test depth?

Hi
Depends whats in the ground iron /trash etc , that applies to any metal detector , Worth taking note that the TGSL are very sensitive to power lines etc , so much so that if your very close to a electric pylon it mutes the sound out as if its turned off.
Built two of these in the very early days with different mods etc and both do the same.
You need to be in the middle of no where, correctly ground balance the machine and it will perform ok.
I still carry one of those in the van and quite often give it a blast if on site work or working at a customers farm.
All the best
Regards Dave

Ordered EDU kit, hope to get it working faster than paku did Good reading here, thanks for that.

Yes your ground balance will greatly affect silver depth. Try a bit of gold for a better test...

[jladre]

Depends on your ground and settings.

I use a the IDX


One nice dry sand I loose virtually nothing


Most ground I loose about 25%


on ground with a lot of coke in it. If I move the ground balance to stop the coke sounding I am getting about 50%


On a wet beach where I have to turn the threshold down I am only getting the the top few inches.

Try with the discrimination turned right down.

Try something other than silver do you get the same bad results

Try adjusting the ground balance. Mine prefers to be slightly positive.

Try in all metal mode are the results the same or better


I am sure we can turn that frown upside down

Thanks koala my friend.. i will try tommorow.

Im a little upset .... in air test i got 27cm on 50cent silver us dollar but when i buried at about 10cm in soil i no longer detect it.

bring out you tgsl and test
