I recently downloaded his pattern to my e-trac. I seem to be getting more false readings...am I missing something? Do I need to adjust any of the settings....sensitivity,audio,discrimination...etc. I am currently running manual sensitivity 24 and tone id multi and conductive and also tried the 2 tone ferrous,to me it still is picking up more falsings. I have also done the noise cancel. Also where I live there is a lot of red clay,will this alter the detector when compared to an area with very little red clay? Thank you
