like the sound of idx is more interesting if you use the voice of cscope 1220B. has anyone tried it please share it

Hi
cscope 1220B robust scheme?

[gurdal]

version 1.x is not very usable, you could try version 2.0 instead: https://www.geotech1.com/forums/show...449#post269449, the pcb can be updated easily with the schematics, but you would need an additional led to indicate that MCP602 is in saturation and a MCP1525 that gives a precise adc offset of 2.5V, otherwise you might need to edit and recompile the source code to manually adjust your offset e.g. 2.49V that could trigger more noise if if has a different value and/or to tune other parameters that are hard-coded and cannot be changed in the running firmware...

thank you so much

Hello friends. I am looking for the .hex for the Geotech VDI that has the contrast control included. Does anyone know where I can find it?

I ask God why the threshold is not like a metal detector whites the sound treshold. Sound tresh on IDX has a lot of functions

Hello friends
I ran P12F683 led vdi for testing.
led gives late information.
Is it possible to edit?

Hello
Please please tell me how to set the coils.

thank you WaltR,

VDI doesn't matter.
I need explanatory diagram and information to add C-scope 1220 audio vco.
i need your support in this regard.
Is there a PCB floor file with potentiometer for the front panel in the picture?
Best regards

Not really.
The PIC is not a fast processor and there is a bit of math going on to determine metal type.
Same with the other VDI PIC displays (I run the Graphics version).
In field use it is the audio beep that one listens for to know there is a target. Then wave the coil back and forth across the target to get a VDI. The beep is used to 'pin point' target location not the VDI.

IDX Pro is in a schematic eagle version

[liekwang]

I ask for help, does anyone have the eagle scematic format in eagle version, please help,

[tomec123]

Yes, I will try that at the weekend...thanks a lot.

[dbanner]

Hmm... Interesting.

Can't say what's the deal with the coil you have.

But you can still try to match the resonant frequencies I posted above. Just use different cap values.

I also have the impression that a wrong spool was sold to me. It comes from an Italian dealer via Eb..y. The spool looks exactly like the Quicksilver shown here and is also labeled and was also offered for the Fisher CZ. Maybe a mix up ??? :-(
It is of course tragic if the coils all look the same, but are built differently internally. Indistinguishable for an unsuspecting user.
