Unknown detector

Dear Friends

One of my friend built this detector from original device but He don,t know about coil.
Onebody know coil it will be good.
He says this detector from England and if one metal near the coil tune and detector signalling this metal after tuniing.İf we show AG to coil detector signalling only AG.İf any one knows please help about coil.
Aykurt is my friend name not model of device.

Hi,
detector uses some kind of filter to do programmable disc. Most common is notch disc. This way there is a small window that will ensure that only wanted metal is detected and everything else rejected. I don't know what model could be. Seems an older 80's model.

Best regards,

Looks like a Cscope, parts as bc 184 and bc 214 are in Cscope
Look at the coil connection, cscope uses a hartley osc. so 2 transmitcoils

My guess is that it's an early Cscope. The PCB edge connectors used in this design are similar to another Cscope that I've seen.
Would it be possible for you to post a higher resolution version of the first image?

....


Maybe some old White's ....??

Although label is on Turkish language.....must be some independent manufacturer from Turkey?

Think it is a Cscope 770D ( 1987 ), if you can give a better *.jpg ?
Scope has sometimes a pcb also in the coil.

Its a long time ago I made some coils for cscope, think the working freq was ca 17 khz, It uses a Hartly osc. this meens that the transmit coil is built as a coil with center tap to ground. (2 coils)
For a 20 cm DD coil , Trans: 100 windings .30 mm wire.
make after 50 windings a tap ( connection) that has to go to ground. You now have a coil 100 windings, ( start 50 grnd 50 finish). Connect it to the transmitter and adjust freq. with a cap for ca 17-19khz.
The receiver: 100 windings, also adjust with cap for working freq.
Adjust as a normal DD coil, if you cant get u nul than chance start/finish from the transmit coil ore flip over the rec.coil.

BUT: can not see your drawing very good, sometimes Cscope has a extra board in the sears coil, look on your board if the transmitter an recever part are there.

Good Luck
