Contribution to global warming by Australia. Australia has one of the highest per capita emissions of carbon dioxide in the world, with 0.3% of the world's population it produces 1.4% and rising(not the .08% the  finders forum dope "Inhere" claims!) of the world's greenhouse gases. Australia also has the highest per capita emissions in the OECD, with 26 tonnes of greenhouse gasses being emitted per person every year.
Australia's C02 emissions rise for the 4th year in a row.

 With the Thb set at  null and the QED  Gb what are users finding is the most common hot rock tone- rising/falling/ usually both?

Hi Doug,
unfortunately hot rocks can be both. Hot rocks are just yet to be decomposed material, noting that the surrounding ground is really just fully decomposed hot rocks. So the rising or falling signal is relative to the GB set for the surrounding ground and should be able to be MGB out.
Something I am going to try out next week is to check whether I need to adjust the GB for the surrounding ground once MGB over a hot rock. In reality there should only be a few clicks in it, but I will report back with my findings after next weeks test.

Goldman did you get to do that test after MGB'ing over a HOT rock and then checking if the GB still needed to be adjusted for the surrounding ground?

Hi Gary,

Testing performed to date confirms that hot rocks can be GB’d out, however the GB movement is too much to be able to continue detecting the surrounding area without re ground balancing.

I suggest that the 11 elite that I’m using is a very sensitive coil, so using a less sensitive coil ( i.e. not flat wound) would help in controlling hot rocks and ground noises.

Cheers Goldman
