Maybe they meant a Magnetometer or ground penetrating radar.
These aren’t just a little device you pin on your shorts though. You might tow it in a trailer behind a 4 wheel motorbike over a grid pattern.
Or for the ground penetrating radar pop it on a small private plane and do a series of flybys
I don’t know anything about this other than what I’ve seen on Time Team (and supposition), but I think that might be ok if you’re trying to measure the size and density of a mineral deposit, but I don’t think you’ll be able to detect a grave.
I think I’m conflating GPR with… something else to do with magnets, but I still don’t think you’re going to detect a grave from a plane.
Isn’t the gpr the one they use to detect bits of wall and stuff and cops use to detect recently dug ground (because it’s not as compacted). Of course if they hid the bodies during construction it might not work so well as it would all be dug over.
There are relatively small buggy/wheelbarrow ones that you walk the grid pattern with.
