IDX.TN 2025 + VDI

[surf-tech]

A video of the new IDX.TN 2025 device, with all files available on the you tube channel... The device operates at high efficiency, and the results are more than excellent.
Some circuit paths on the board and some values have been changed compared to the original device.

Video and files are available on the channel

Are you willing to share your schematic optimisation here for consideration and discussion here?

[ArchibaldSTM]

It is not clear what has become better? Standard IDX...

There have been changes in the PCB routing to accommodate tight spaces and to allow the use of connectors instead of directly soldering wires. Some resistor values have been modified, and a charging circuit has been integrated. Parallel capacitors to the coils were added to the board. to facilitate operation.

[ArchibaldSTM]

All this is good, but the question remains. What improvements did these modifications lead to? Did sensitivity increase, for example?

Of course there is no problem. There are no major modifications so I thought that was enough.

Watch the air test video on the channel. It detected a coin 55 cm away.

We don't see the schematic, we don't see 55cm on YouTube.

The device searches in the ground, not in the air. Air *tests* are enough --- show in the ground.

Yes, the sensitivity has increased significantly.

[surf-tech]

The device is good, and the test is clear on the channel.
If I do other tests, I'll talk about it here.
As for the modifications, I made other adjustments, but the result wasn't better.
If there are any suggestions, I don't mind.

Good afternoon. Please don't be offended!
You haven't shown any results.
Show the results as follows:
- how the MD behaves in general (on clean ground, in grass, etc.), stability, etc
. - in the test of targets in the SOIL LAYER. Do not (!) dig a hole, put the target and bury. Namely, in a LAYER OF SOIL (a pit with a side pit for purposes at least 10 cm deep)
Then we can talk about something.
Air tests of the coil and the block, which are in a static position on the table, show nothing (!). Air sensitivity is not difficult to raise. Everyone knows how to do this.
Therefore, once again, please do not be offended and we are waiting for tests on the ground and in the reservoir.

The air test is a good starting point, it shows excellent results = congratulations.
Put the coil on the ground and wave a coin, call as results.
You may need to reduce the gain of the Rx amplifier to make the device work in the field, to see if you need to add U balance displayed on the LCD, to the program.
