[forst]

for Jonas . Did you biult this layout of Bandido II from Quink?

[Johnny]

Yes this bandidoII eagle layout is 100% working, nice work from germany

Hi Johnny,

Did you build it ?

yES i BUILD IT BUT IT DOESNT WORK. i DONT KNOW wHY?

Have you read the error.txt inside the archive:

- All 2N3904 and 2N3906 must rotate at 180° on the final PCB

Can some one tell me, how deep you can search with bandido? For example 30-35 cm² gold or silver throng.

Hi,
I get a small gold ring (1.5 gr) at 18 cm in disc mode, 21-22cm in all-metal in air test.
Got 1eur coin at 30 in ground with DD coil 22cm diameter.

Don't know your object but think could be detected at something between 40cm and (maybe) 50cm in air test.

Best regards,
Max

thanks for your help,
Your answer mean for me is , this detector is not for me, I need 1,5 metters and 2 metters deep scan.
Do you have idea for this kind of deep machine that I can build? what kind of machine I must look for? Gpr, metal detector, Lrl , e.t.c. Do I have any change to search, deep as 2 metters by metal detector(for 30-35 cm² object)?
What is your opinnions about this?
thnks

Hi,
well if your object is 30-35cm2 area it's hard to be detected above half a meter with a conventional device. You can get best performances with pulse induction metal detectors with large loops e.g. 50-60cm diameter or 1mtx1mt and avoid vlf/ib/tr but this way you gain just few 10-20 cm but lose discrimination. Target is too small for metal detectors range.
I think that a good gpr could find it at 1mt depth but there you must rely on resolution of device that must be high. I think that no LRL could find it cause most of them are simply electrometers and can't help you in this kind of search.
With a metal detector pulse induction type you can search also over 4meters depth but not for 30-35cm2 object but only much larger objects - 2 meters for such an object seems to me have no solution in the metal detector scenario.

Best regards,
Max
