XP DEUS hot program on hot rocks and rusty iron things

The conclusion is that my custom program (based on preset 2) ignores these unwanted objects way worse than the Hot program. Be careful though with the horizontal lines (sign of hot rock) and ID around 92, those can be copper coins. The copper coins have a shorter beep whereas a hot rock makes a prolonged sounding line. Depends also on your type of hot rocks so dig a few to be sure.
Detectors will often have a hard time telling apart bottle caps. they might give a good or bad or mixed sound, depending on the material and whether they are rusty. Pull tabs are a special kind and will always sound good. Most here are id 65-68 (old big round ones are 72-77-ish). Unfortunately, this is the ID-range that decent gold rings might pop up in. You can take the risk and stop digging the specific pull-tab id's.
