i do not think there is a thing just like "deep gold detector"

no such thing deep gold detector. only deep metal detector. (gold is metal) depth will vary depending the size and type of metal to be detected and soil condition. and the very important is your knowledge in metal detecting. it's not like pizza ready to eat. absolutely metal detecting requires knowledge in metal types,soil types,ground condition,and rf,electrical,other interference etc before metal detecting. knowledge in electronic circuits is a huge advantage in metal detecting.

I know that Delta Pulse is large deeply buried metal objects, but a liter of paint 50 cm vazduh a poor result, that is your score with the coil to 40 cm maximum.??

Pogledajgo this pdf document ivideo clips in the document.! That your score with the coil to 40 cm maximum.

I'm not sure you can see pin the other to the c15 electric scheme is connected to GND and the assembly scheme is not, see ...

Check this out ... on the assembly (shematic 2) are set TR2 and Tr3 facing the other way around. If you look shematic 1 (e scheme) see that the collector (C) of TR2 D2 is connected to pin 2. And on the assembly (shematic 2) scheme is emitter (E) transistor TR2 (BC546) is related to D2 pin 2. Also with Tr3, now lems of transistors so confused. Compare shematic shematic 1 and 2 do not match ... what exactly?
