tx-150.tx power max-250.delay1-30to130.delay2-50-450 microsec.

Thanks

Ok Sasho,

How is its detection?

I am sascho friend. This is very good detector. Dig is big problem.

Hi all,

I made this PI. It works excellent and can beat my Deltapulse.
I suggest all to make it.

Many thanks to Sascho for this design,

Hi! 1843

I would like to make this detector. Can you post the PCB with components here?
Thanks in advance

Hi there,
I made that on beradboard and do not made a pcb for it...
Although this PI works straightforward, its detection depth is lower than Deltapulse.
