the demo prpgram that came with my DFX 300 I edited it to look just like Larrys Program and I dont know if its just me as a beginner but it was making my DFX go crazy!... I could move without it setting the metal dectotor off and was giving off all kinds of readings.... Can anyone point me in the right direction on what I need to do to fix this are to fine tune it a lil more... im useing the 9 inch coil if that helps... Thanks!!
