ionios335, welcome as a new member here.
GG AL707 schematic is well known and tested. You need to read threads about GG Al707 from start.
Capabilities to detect something with GG AL707 are more theoretical than practical (main problem is proper antenna tuning). In all cases you can detect with this devices a bigger ore underground deposits only. But device is cheap, easy to build, work better than all mineoro and other scam devices, so it is worth to try.
