So if its high pitched, soft and distant, it will almost always be a deep non-ferrous target.Ground Balance is left in auto.Manual Ground Balance is great for neutral ground and beach work, but on sites with high mineralisation and hot rocks, I wouldn't take the chance. If you run the gain at 20, you will find surface plough shears will give sharp high pitch responses, whereas deep high-conductive non-ferrous targets will sound soft, almost distant in their responses. If you get a repeatable two way signal using my modes, chances are they won't be deep iron.

The CTX 3030 is a lot better at discriminating iron than the earlier FBS detectors. This setting will give you an audio indication to deep high conductive targets.

However, I would always recommend finding the correct manual setting in this situation.Volume Gain is set to 20 (max 30). Auto-sensitivity is very good on the CTX 3030, and if searching iron nail infested soils can bring good results. Important non-mode settings Sensitivity is used in manual, and set as high as possible. So now I keep the most recognisable elements together, which are the tadpole patterns. The problem with that is I couldn’t see which mode I was in as they looked very similar. In part 1 we built the mode (program) and now I would like to take a closer look at the settings and the thought behind them.The first mode with the tadpole patterns is the main program, and the clear screen mode is the mode I switch to if I need to analyse iffy targets.It doesn't matter how you mix and match these patterns between the two modes, and previously I mixed a tadpole and clear screen pattern on each mode.
