Really need someone's help if possible on this... I have been desperately searching for some buried USB sticks and efforts using pinpointers and standard detectors have not worked. The first question is, can USB drives be detected in the first place if they are buried between 6 and 12 inches in soil, but first placed inside plastic wrap, plastic food containers, and bags and sealed with duct tape? The circuitry of the drives would also be inside the plastic casing of the drive. Second question - if they can be detected, what kind of detector should I use and more importantly, what settings should I use on the detector? I have tried using a Fisher F75 (which I believe is a pretty good one?), but I am a complete beginner. Much appreciate any help on this! Btw I dont know the make of the USB drives or what metals they might be made up of.
