[QUOTE="Wally69, post: 152348, member: 1916"] You probably hit a honey hole with the SDC and all the small gold was sending it into a feeding frenzy. ;) Once I worked out that several auto tuning resets can settle the machine down, basalt hot rocks and really bad EMI are the only experiences I have with SDC instability issues. I have had it running in stream twice for short periods of time and haven't noted a difference in background noise. Not sure how accumulations of black sands affect the SDC but would like to hear of others experience in this regard. The SDC is a proven killer on small shallow gold, the only problem is I still need to spend considerable time to find it. I have seen a 4500 with a sadie coil in action by an experienced detectorist and it can pick up the small stuff (sub-gram) but still carries a lot of EMI noise compared to the SDC. [/QUOTE]
