Good advice thanks. I referred them to a reputable GPR company as I don't have a GPR system. We're trying to find someone with a two box detector or a good PI one with a big coil. It's worth a shot.

Lots of good tips guys. Bottle probes seem like a good idea. I'll try to find a detector club nearby where someone has a two box detector. We'll also try to use GPR from a local contractor.

Yeah that's a good idea. The client has already gone over the area with a cheap detector. She has no experience but if it was shallow she probably would have found it. We should see if we can find a local detector club.

I'm a geophysicist, I have a lot of experience with magnetometers for mineral exploration. We're looking at using one for this. There are some buried utilities and we don't know what the gold bars are encased in, it would be nice if it was a ferrous metal container. They seem to think it's a suitcase or something like that but we don't know. The utilities and proximity to power lines, septic and other things will probably make the mag difficult to use in this case. I have a proton mag and we will try it but I have have doubts due to the potential interference.

Regarding 2 box detectors, I have no experience with those. Does anyone on here have experience with them? Can they detect gold bars (the size of a Hershey bar) at 4-6 feet? I'd like to know before I drop $2k on a machine.

That's a neat idea. I'll look into that. I don't know if it would be feasible to probe the whole yard but as another person posted we can narrow it down by avoiding the septic, etc.

That's what they told me. Apparently the property has a new owner and they did some landscaping which added 2 feet to the whole yard. It was originally about 2 feet deep.

Good tips. Apparently after the treasure was buried the new owners of the property did some landscaping and added about 2 feet of soil on top of the whole place. It's a 1/4 acre on a residential yard so we're not going to rip up the whole place with heavy equipment. If it was vacant land in the bush we'd definitely do that. This will need to be detected somehow. I am considering GPR but I'm not sure if it would pick up something of this size. I own seismic sensors but they don't have the resolution for this. We also have a survey grade magnetometer but that won't sense the gold, if we're lucky and there's a lot of ferrous metal in there too the mag will pick it up. There are possible utilities and a septic system so that will probably throw off the mag. I'm looking for a deep metal detecting option, possible a micro-IP or resistivity system. I don't have experience using that equipment for this application though. I am a mining exploration professional not a treasure hunter but this is a cool story and I want help them out.

Hey guys, I was recently contacted by a local person with a personal treasure story. Apparently this woman's ex-boyfriend buried a box with several gold bars in their back yard. It was meant to be a surprise for her but he tragically died in a car crash and didn't get the opportunity to present her with it. She learned of this recently after his death. She knows which property it's located on but the area is 1/4 acre in size and she figures it's buried 4-6 feet deep. There are apparently several gold bars the sized of Hershey bars. There is supposed to be other treasures but she doesn't know what those are. She doesn't know what kind of container this stuff is buried in. If it was metal we could find it pretty easily with a magnetometer but she's not sure. What technologies are available to detect at that depth? I'm not aware of any detectors that can reliably go that deep.
