No, I still need to learn. I can't improve the mini pulse.

Hi ZOUjiarui,

SuperScan PI with two coils.... Nothing special. Without any circuit modification you can connect all kinds of coils like DOD, DD, Concentric RX-TX, separate 2-coils (RX & TX), Mono, Dual-field coils, big frame or double frame coils to the MiniPulse. Also the Front-end design is much better than the one from the SuperScan Pi.

GEOMAX, thank you.But I have initially fix the super scanned sketch, should not turn to another PI at this time.Super scanning it uses two coils, greatly reduces ground reactions, which is very beneficial to me because my hometown is all high mineralization red soil.

Another thing.... but this is my opinion. The MiniPulse + the modifications I mention should be much better than the SuperScan Pi itself.

Hi ZOUjiarui,

why do you not build the Geotech MiniPulse? This is almost the same circuit as the SuperScan PI. The MiniPulse is well documented and PCB's are also available. One additional feature of the SuperScan is the "power switch" (12/24V) which is not in the MiniPulse. But with very little effort you can add it to the MiniPulse circuit. Further is the "Response Speed" poti. Just add the poti at the same position to the MiniPulse as it is seen in the SuperScan PI and to add the meter circuit should also not be a problem either. You can add a meter cicuit to any of the detector circuits floating around the Internet. At last you can add the reset/tuning circuit as well to the MiniPulse too.

Hi, kt315. The mistakes on the drawings are probably intentional. Few people are willing to say a word more about the correct scheme of the machine. None of the drawings are correct. They all contain mistakes. One thing is good, there is no problem with the PCB layout

[ZOUjiarui]

There is also an unconnected position, which I guess does the same thing as the above.

[ZOUjiarui]

There is a big difference in the position of the super scan sketch and the PCB, it is the place of the ammeter, it is hard to say who is right

[kt315]

can anybody share pics of high resolution (5-12 MB size) of the Eric's pcb? long way to result i see here... so if you did up the matter....

Most likely, it is used to choose to switch the potentiometer R2 from R3 to R1 in order to double the frequency of generator 555.

Hello, do you know what the 150k on the 555 foot 7 does?
I found that it doesn't have any connection on the PCB nor on the circuit diagram
