KT315, Thanks for the photos, I built this detector some time ago, with some doubts and improvisations. The images are very useful to me.

[kt315]

welcome. i hope with my info you will get the end result. i soldered all back now and will search the coils.

can't unscrew HEX screws on coil ((( it is unstandart -! not 3 and not 4mm bites. something near 3.5...
must grind out one... or it is in inch standart???

Yes it will be inches. Most likely .125" if you say it is close to 3.5mm.

Tf900 is close to Tm808 and Cscoop9000 but there is no Vu meter in Tf900

in C-scope is Vu meter. it's sure Discovery TF900/TM-800.

Well, that solves a model connection problem. Thanks KT-315 for the validation.

Another quickie.... TF stands for Treasure Finder. There was a TF-600 and it was called Treasure Finder so the definition is valid...

There is no question. I once visited the Discovery factory and there was a rack of C-Scopes in the production area. The owner (Roy Van Epps) told me he made them for C-Scope.

My TF900 project
The selector key was replaced by individual lever keys.
The reset button was adapted to an optocoupler, because the cables introduced a lot of noise.
It seems to work well in the backyard of my house.
It is sensitive, but if the gain is increased too much, it becomes mechanically unstable.
No field tests have been conducted yet.
I hope to carry out more tests in the next few days.
Thanks KT315 for the information provided.

nice project.
the cable to reset knob is shielded one. also aluminum housing is connected to ground and by same way shielded.
thank you.

Perhaps because the box is made of plastic, and does not have any shielding such as graphite. The handle of the support is longer and the cables are longer.
