Seismic Imaging help.

[wreckee]

Well we tested the big detectors , GEM 300 EM meter , Aqua Scan AX2000 MAG.... which you will find some great targets with but only if there iron or steel , which we are not looking for and ground resistivity which will not work all that well on wet sand so can anyone tell me how Seismic Imaging works in wet sand ?? Cheers , Nick.
