Bravo...

For common progress with common efforts!

and what is the advantage compared to not bipolar ?

Hi pito,
The advantages of bipolar PI:
1. Eliminated 1/f noise of 1-st stage - possible use of more cheap IC
2. Eliminated influence of magnetic field of the Earth - no need of EFE samples - more simple control pulses
3. No need of sophisticated schematic for automatic moving of the positions of the sample pulses for big or too near targets as in the schematic of Delta Pulse (XR71) MD
4. This solution safe lives - no danger of exploding of mines with magnetic triggering
I hope, this list answers to your question.

Very nice pi detector ,good luck.

And fifth reason - Carl declared he now design only bipolar type of PI MD - follow the motto - "IN CARL WE TRUST"

Hi, Detectorist#1, do you sell boards for customers in Bulgaria to order from you? There was a colleague who wanted to contact you, if he could leave me a viber or phone number. Thank you.

Hi algan,
The project of the two PCBs is property of GeoMax. Only he sell the set of the two PCBs on eBay.

Okay. Thanks, my colleague and I should order from there.

Hi Algan,

If you place a joint order with your friend, you can save on shipping costs. Each additional PCB set is included at no extra shipping cost.
