I dont speak russian well.
Ja ne govorim po russki horoso.
Im Igor Popovic from serbia.We also make many metaldetectors homemade.
This is vlf that is fairly easy to make it goes quite deep but the discrimination is its weak point however its very stable so it does work fine.
This is my work and i give u the schematic.
Now...looking at this schematic, it is so obvious that this detector is a sort of sublimate between White's, Fisher 1225 and Tesoro. Although we can meet simillar or exact the same stages in other projects too.
Also, recently, i discovered another fact; originally, this design came from Bulgaria. I guess some good bulgarian enthusiast payed a lot of effort to experiment and finally got this project.
Looking at schematic..man can be fooled by it's simplicity and wrongly to conclude about it's performances.
I took it outdoor with me few times and was pretty amazed with it's performances and depths i reached.
Only one minor drawback is; it can suffer from minor instabillities if Sensitivity is adjusted to maximum. Lowering Sense device becomes very stabille and loose just a bit of depth.
