Hello Maca,
Good if you have experienced the pulse induction circuit ,you can know built the Goldscan ,when good ajusted it is a very good machine for hot soil.If you make your own circuit board ,i will make a little change for two 4700 uF en //  o a 10000 uf capacitor ....this will give you a very good stability machine.
have a good day
Alexis

Thanks for the advice, yes I do have an oscilloscope which is good.   Can you confirm that the PCB on page one has no errors though ?

Hello , I think it is good , see Eugene check it ,  you do not have problem , the first pcb i make was very simple  and in 2 parts ,single face, and it work well...the more important thing  it is to bring  in the first  stage  all the ground patch  at ONE part : the plus(+) of the big capacitor(4700 o better 10000) like i said  in the text of my schematic....
