I made this video to demonstrate the audio of Mixed Mode. The target read 8.5 inches, deep enough to investigate. It turned out that this target was nothing more than a "cold rock". Unlike "hot rocks" which hit on +95, these minerals usually hit in the 0 to +5 range, but may sometimes mimic a deeply buried good target (as was the case here). A quick way to identify these targets (which can be a nuisance, especially at higher sensitivity levels), is by digging a quick 2 inch deep plug. If the target is in the plug yet still gives a deep, inconsistent reading, it is likely a cold rock.
