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.

Evening all,

I guess this is a question mainly for Howard.  Just got a question about the Ferrite EMI suppressors that are provided with the QED. As per the online manual:

"Included in the base package are 2x ferrite
EMI required by Australian
Law. One ferrite EMI suppressor needs to be
fitted to the search coil plug inserting into the
detectors control box for each coil intended
to be used with the detector."

I'm not a technical sort of person so am wondering if the EMI suppressors are to help reduce the amount of EMI coming to the detector or to actually reduce the amount of EMI emitted from the detector into the surrounding atmosphere. 

Just wondering if they are actually helping the detectorist in any way or just provided to comply with government regs?

Thanks in advance.  NE.   happy face

The ferrites work both ways, reducing transmitted and received EMI. In no way do they reduce detector sensitivity to targets.

Aha, thank you for the reply Bugs.

Reduced, received EMI is the important one.

Thanks again      happy face
