Superscan PI

[GeoMax]

Hi,

does someone knows the function of the diode in front of the 555 timer (Pin 7)? See red box in the schematic.

Thanks

https://www.geotech1.com/forums/show...oldscan-IVHere it is slightly wrong, the forum has the correct schematic to fix it

sorry. i'm not keeping the files made in sprint layout. sometimes they seems much crocked for me. yes, happy new year to you also.
i am ready to keep GERBERS of high quality layouts, although, but do not meet.

Good morning KT, I'm looking for a file I saw somewhere on the forum, ? from goldscan and it was a reverse copy made through original photos, if you can help me by directing me with information here, since now? I thank you for your availability, otherwise I thank you anyway, and a new year filled with health and good achievements, thank you.

I don't wish to disassemble it at the moment. Even If I wanted the device is not here with me. You're on your own with this.

The bus is only 2m. What's the advantage of this distance

Coil 40cm, car 2m https://www.teknolojiekibi.com/yeni/...topic=8096.520

I have a question, to make a coil of 10mx10m, small coil in the detection, can this method increase the detection depth? Can the machine still work stably? Can someone explain that? Thank you

[jeep6789]

Can't be

[magic12]

Some one made a claim
that superscan was able to detect a lighter in the air
at 2meters
with a 70cm coil

thats insane and i want one

[jeep6789]

I don't think it has any advantages, the detection range is far less than delta pulse, I wonder if it is my production reason, if someone made it very good?

whats the performance with a coke can object small and bigger coil
