Really sensitive pinpointer for grain size objects = Can we see video ?

This is the schematics of pinpointer oriented to large use of SMD components

This is whole PCB project oriented to large use of SMD components

Last time have tendency to manufacture integral circuits and low power transistors in SMD cases only. That's way I attach the variant of PCB with SMD integral circuits and double variant of all transistor cases - THD or SMD

For people that have possibility to do PCB in factories, this is the whole project.

This is the project of PCB with 21.5mm by 130mm size for using of 25mm PVC tube as front end of pinpointer construction

The aim of this project is to create really sensitive pinpointer for grain size metal objects and to share this schematics with large volume of DIY peoples.
