i did not checked this mod, do not have detailed info. koliaj wrote it gives more stability. in my opinion DP works perfectly
and stably, in a case you did all right.

KT, I saw a mod for audio for Delta pulse "koljaj". Have you any more info on it's implementation.

I'm not an electronic professional.
I collected the payment under the Turkish scheme. I do not work in automatic mode. But works in manual. For the test at home, I use a coil 30 cm twisted pair wire 3.3 Ohm resistance.

To improve audiovisual information (when searching for other metal detectors except sound look at the screen to determine the signal strength), you can connect to the Board of Your development LCD Turkish development, as a simple display that shows the battery level and signal strength.

The assembled Board was connected to the test coil when changing the settings (sens; tr.hold) the sound appears and reset, the metal reacts.

Greetings to you, brothers and sisters!

I assembled the device on a single-sided Board.
Immediately am asking forgiveness, that my of knowledge in radio electronics not strong, so can be quite elementary questions). No offense :-)
