Ok, thanks. I was interested in the type of magnetometer researched (eg. fluxgate, caesium, potassium etc), their sensitivity, the type/mass of the target material and whether the proposed search was as a plotted and post-processed survey or simple MAD etc.
I'd be keen to follow up if you've got this detail? That's the research and process I'm presently following up so if there's someone to speak with who has been through this, at least in part, it could be useful.
FP.
