              Can you say a few step how to prepare IGSL before searching.

                That depends on momentary conditions on given soil and momentary intentions of operator. But let's presume that coins will be most desired target. In that case Disc1 (Ferrous rejection level) is set above "3", Disc2 (Nonferrous rejection level) is set to "0" (complete rejection)....(now reading this i see logical mismatch here! Disc2 better to be called "Nonferrous accepting level"). Disc Sens to maximum, Fe Sens to 70%.... and those would be adjustments i would start with.

                  Also some more info on pre-set of GB? Becuase these are trimmers it is implyed that they are to be set for average conditions and then left alone. . Becuase the two channels have different functions are the GB trimmers to be set identical? or biased slightly +- to augment the respective channels intention? What was your idea on these two trimmers when you designed the machine?
                  I am still slowly thinking through the operation of your design while awaiting a time when I can build it and play.
                  Thank you friend.

                    I have been looking at this and the more I study it, the more I like it. What I think I am seeing is a possible low (437 hz) tone, high (1.75 khz) tone and a mix of both at the same time depending on where the Ferrous/nonferrous rejection levels are set. If both controls had 0 to 100 graduated scales and Ferrous was set to 75 and Nonferrous at 40 for example then any target below 40 would get low tone, above 75 a high tone and between 40 and 75 both tones. I may be off track completely but if it would work this way it would be awesome!

                      Sorry I didn't notice you answered the GB preset question already. And it was even my question then too.......too funny. I had just missed it amongst the text of the phase range discussion somehow.
                      oooppps.

                        Yes, that was the idea.

                              is this new project easier or harder to built than the previous TGSL
                              many thanks

                                To make such or similar detector is not hard, but making good coil is always tricky part. TGS/TGSL and this one, IGSL, are sharing the very same coil. So, if you had problems to make it for TGS - you will also have problem to make it for this one. Pcb, itself, is pretty easy to "populate" with components, always was sweetest part of process. So i can't answer you properly on your question. All depends on your own skill and experience.
