Hi Steve, I googled the Makro Gold Racer for hints and settings advice and came across your review and this forum. I just purchased the large coil and when I first put it on it went crazy flashing numbers like it was possessed. It was unstable. The manufacturer said to bump the sensitivity down a notch. I did and it seemed to help, but it still freaks out every so often. On one hot day I couldn't get it to settle at all. Have you come across this and if so, what is your solution? I am searching in mineralized red dirt that has been turned by dozers due to recent fire.
Settings: Sensitivity 30, Threshold 25, ISAT 10
Thanks for advice, I know this is an old thread...
