Hi all,

Is it possible to detect a coin at 2m under the soil by a GPR?
I want to buy a cheap GPR!

Hi,
at 2 meters ??? E.g. a 1cm diameter coin ? You need enormous resolution... that pratically no commercial or homemade device has.

No, it's impossible in practice.

Thanks Max and Geo,

I want to buy OKM-GEMS.
What is the minimum object size that can be detected at 3m under the soil by this GPR??

OKM is good magnetometer
- antena is two differencial connected fluxgate magnitometers ( https://www.geotech1.com/thuntings/s...3&postcount=15 ) in PVC pipe,
Doppler Sensor KMY 10 in pipe not work ( http://www.ortodoxism.ro/datasheets/...on/1-kmy10.pdf )

and at 9.35 GHz GPR will be work to 20..30 sm max
