Experienced Users Needed: Reliable Archaeological Detection Beyond OKM (15m Depth)

[eneez]

Hello,




I’m looking for reliable ground-penetrating technology for archaeological prospection. The soil here is a mix of earth and rocky material, and I need to detect human-made objects up to 15 meters deep.




So far, OKM devices have been criticized everywhere I ask, but no solid alternatives have been suggested. Any recommendations from experienced users? Practical advice is much appreciated.

Hello, OKM is just a Turkish company based in Germany. All its devices are just ordinary magnetometers wearing a cosmonaut suit. Only their first device, the Future I160, is effective for vacuums because it was designed by a German engineer before the Turks took over the company. For the depth you are looking for, you need a real resistivity meter, not those sold by small retailers. Look for a manufacturer who only sells cutting-edge equipment.

Thanks for the explanation. Given your experience, what would you recommend for detecting tunnels or other underground cavities? Which type of equipment or technology should I be looking into?

A Wenner-type resistivity meter would do a pretty good job of detecting cavities. Avoid the garbage models marketed for treasure hunting like "GPL" and "Accumeter".

On the DP forum I also mentioned a high-power PI detector. 50-100 amps, and then test it on likely targets. I would expect 5m is possible, but probably not 10-15m. This is something you would have to build.

Hi Carl,

What is the "DP forum" ?

I told you about the only serious OKM device, here is a serious video of a French prospector testing a nozzle (vacuum) with the I160.
