Both same frequency's are the same. Easy to test if that's the problem by switching the Garrett off. Is the coil homemade for factor built.

ho said this excellent performance outdoor try and tell me if you have any interference or not, mine works fine inside but goes outside fluctuated randomly, maybe 'cause my boyfriend uses a garrett ace 250 its frequency is the same I do not really know.

Great job! How do you exactly proceed to null the coil?

Great results Ropcsika! Can you give us more details about your coil? As well, can you show some
pictures of your PCB?

This is my idx pro. I built latest version of Eduardo. I tested the maximum depth.

I am just having some trouble with the two tone board connections mainly the u4 connections 1 2 3 what ones go where?

OK, guys, I made a comparison between the silverdog PCB version and the latest modded version of Eduardo. Tested with a same coil I did not mention a noticeable difference in the sensitivity. In my experiment the discrimination of the silverdog PCB was better. After a hour of experiments with the Eduardo latest version something happened - it started to work horrible in discrimination mode and the all metal mode lose the threshold totally. It started to produce a continuous loud sound. So I thing that something burned out. I did not changed anything in the PCB. Only tried different capacitors on the RX. As well I tried all possible RX capacitor configurations and my best sensitivity was about 33-35 cm for 1 euro coin. My coil is DD with the exact parameters and properly nulled. I can not imagine how some of you can achieve 50 cm detection distance for 1 euro. You can check my PCB on the image above. My coil is also near to the perfection. So my conclusion is that the IDX-PRO is a nice working project, but it is not a "beast" at all. If you want a good discrimination this is not your project, TGSL is far better.

Thank you ,
I must have missed it some where.
now to hunt down the connections image again

Is this PCB for 2 Tones correct??

[gtdavid]

Ok just made my self sound stupid there in the coil as it is a shop bought one.. yes??
What other modifications would be needed for that type of coil?
and also is there a schematic for the two tone mod as i would like to make one with a prototype board and i could only see .lay files..
Many Thanks

hello,
i am going to connect a fisher cz coil (the type mentioned at the start of this thread) what transmit and revive capacitors should i use ??
many thanks
