TESORO GOLDEN SABRE

[mostafalesnar91]

Two ways:
First, set to Disc mode and disc pot just below foil.
1- use a small piece of ferrite, I use a core from an adjustable RF coil.
Wave the ferritte over the coil and increase the GB pot until the TGSL doesn't beep. Then wave a silver coil over the coil. the TGSL must respond to the silver. If not then the GB pot is turned too far so back it off.

2- In the field with minerialized soil. Pump the coil up and down gently, don't bump the coil onto the ground. The TGSL should not beep. If it beeps then increase the GB pot until it does not beep. Then sweep coil over a silver coil to ensure it still detects silver.

Note: the GB pot is very, very sensitive. If using a one turn pot it only takes a very small fraction of a mm turn.

disc mode or all metal mode??????????
i tried with frrite correctly you can see it in this video
but when i move the loop, my device makes noise!!!!!!

[mostafalesnar91]

you still need the oscilloscope for an optimal adjustment .. you have very little range .. with mine moneta and ring at 40 cm .. the adjustment of rx must be 20 degrees to the right of tx with the oscilloscope ..

when the separation mode works correctly
Is this not enough for coil nulling?????

the balance on ground is doing in ALL METAL mode (PINPOINTING). i dot not see waltr mentioned this.

I completed this project without using oscilloscope!!
just with a simple multimeter!!
very very easy!!!!!!!!!!https://m.youtube.com/watch?v=eEQmZNyUJo4

question

Hi
It is very beautiful !!
What kind of materials is the body of the device (handle, interface tube from the antenna to the handle of the device, etc.)?
Have you put the main board on the antenna?
Thank you

Hello
I am a new, beginner and novice member
The attachment I received was not of good quality and was not clear !! Is it possible to send me a complete file of device construction (PCB details and circuit and antenna schematics)?

Thanks!

The two caps , above and below the LM358 are 0.022uF. These are on the feed-back of the first differential stage.

The two below "RFc" are for RX coil tuning. Only one is needed and TGSL schematic calls for 0.015uF. The second is to allow paralleling to get the required value for proper phase with coils nulled.

The one above the LF353 is 10pF on the TGSL.

I have just one more question, there are about 4 capacitors that does not have any value. Do you know what values they must be? I attached an image withe these caps surrounded by a green rectangle.

Thanks and sorry for disturbing.

Hello, I want to get the correct files for collecting this device

[cristiano.sar]

Oh, thank you so much. So, this second smaller schematic is not essential? Thanks.
