Just got my 9" round HF coil, got it together and charged. BTW, I have seen others say that the charger clip does not fit the coil but I had no problem with getting the charger clip on.

I have a gold "picker" test card with an apx. 1/10 gram gold piece on it. At 55 Hz,95 sens, and unmodified goldfield program, the coil will hit the gold at 10" in an air test. My soil is not at all mineralized. Other stock programs do not do quite as well

Thought you might like to know.
