Yeah bodgy. I noticed the same. Seems like they are trying to keep it secret for some unknown reason - every report just says "geophysics". But it's not like they invented the technology and those who have bought and operate it would obviously prefer it to be well known, and those in the business would also know what it is anyway.

I first thought they were using early time EM, which might do a similar thing, but the definitive scale was intriguing beyond what might be expected with an EM resistive response. Anyway - they put a picture of the gear on their website which wasn't EM so it got me looking. Hence the disclosure here.

I might have a think where else it could be used in a similar application elsewhere in the world.
