If you have a correct and accurate Lorenz 5 circuit, please upload it.

Thank you for sharing your useful experiences.
So far, a good conclusion has been obtained according to the practical experience, which was not far from the mind.
"The LP5 goes deeper and responds better to small targets, but it does not have the stability of the PS2".

[roshik]

The good power of pl5 is due to its output transistor, and the better stability of ps2 is due to the use of a frequency crystal that minimizes the slippage of produced pulses

Regarding the pl5 schematic, my information is also incomplete. I checked its schematic before and saw some small problems. Due to the unknown number of some ICs, I left it aside.
I think that if the number of ics is identified, minor problems in its schematic circuits can be identified.

please if you have something new sharing on LORENZ in this topic pcb-lorens-5 - Geotech Forums (geotech1.com)

No unfortunately, I don't have more information about the Lorenz Pulse 5 circuit, but I think the op-amps used must be from the TL series.
I think the user named mee has good information about this metal detector, and if he shares it, it will be a great help.

you can check yourself.

Greetings to all participants of this thread. I have a Pull star II built according to this scheme. I am interested in a 40cm probe. which wire is the best to wind, what is the diameter, and are there electronics, resistors, capacitors, etc. in these probes. Thank you.
