Radar is a useful tool with familiar uses such as detecting aircraft and observing weather. It also has some less known applications, such as a technology known as ground-penetrating radar (GPR). Despite the difficulty of sending and receiving radio waves through solid objects, with the right equipment it’s possible to build a radar that works underground as well.
GPR is used often for detecting underground utilities, but also has applications in other fields such as archaeology and geology. For those people in these fields, a less expensive GPR was the priority of a group presenting at a 2017 National Institute of Telecommunications of Poland conference (pdf warning). The presentation goes into specific detail on how to build a GPR for around €600, much less than commercial offerings.
The presentation begins by highlighting the basics of GPR, then details the hardware bill of materials for the transmitting circuit, receiving circuit, and the DC power supplies. It also details the theory behind the software needed to get the circuit running properly, and has code as well.

Ground Penetrating Radar For The Masses - Hackaday

I use it to find out where the bodies are buried. Comes in pretty handy.
$711 to build one. Might even be cheaper in the US, depending on where the parts are sourced from.
Great for finding tunnels to fill them.
Gaza/Mexico
metal detectors go down about a foot or about the diameter of the coil. can this be used to find metal below one foot
I could use some water penetrating radar, for my boating accident.
Gpr
That’s what I need to find the damn moles in my lawn and pasture!!!
My moles self locate they make these really cool, well, mole hills.
I think that may be where the mountains surrounding the valley came from.
“I could use some water penetrating radar, for my boating accident.”
I found it with my 20 year old sonar unit. BTW, never again stash your good bullion with your gund.
“can this be used to find metal below one foot”
Good question.
never again stash your good bullion with your gund.

Remember that Gold is about 1.7 times the density of lead.
That surprised me.

That surprised me.”
I use 18k in my Blackout.
Of course, and that’s where all the guns went. Such a tragic loss.
I believe so.
Build a strong enough GPR and cook ‘em.
Must be some seriously big moles!
Of course, and that’s where all the guns went. Such a tragic loss.

And caused the world-wide water levels to rise!
these low prices are going to release ground penetrating radar to the public.
The result is going to spectacular for archaeology and metals mining.
