Unknown old PD

[J_Player]

Hi J_P.
Before many years a guy from Germany sent this pcb to me as an old Mineoro model(i have yet his email).
From what i see by you, its a pinpointer.
Thanks for info.

Regards

BTW... do you have schematic of discovery TF900??

Hi Geo,
No, This is the LRL forum where we discuss LRLs, not real metal detectors like the discovery TF900 or the pinpointer that humhum wants to know where came from.
You need to ask for that circuit at the Geotech forums from somebody who has opened a discovery TF900 and drawn the schematic.


Best wishes,
J_P

I believe that you have more schematics than all the geotech forum

Hi Geo, do you need TF900 schematic for you new PD?

I think it is only derivative of Whites TM808:

Hi WM6.
TM808 is a different schematic, it is the one chanel from 5900. TM800 (where i have a problem with oscillator) it is the same with discovery TF900 and was manufactured by Discovery, not Whites.

boys: earliers, two antens tf600 discovery, tf900 discovery, tm800 whites´s may be also white tbox tm818, easy fried the receptor oscilations circuit, due when you put the power whit alkaline duracell, energeizer batteries, due to little power circuit configurattions what these md need for work, duracell and other alkalines have very hig milliamperage spectro initial discharge´´
