Surf Master PI no sound

[dbanner]

I built surf pi using layout oxygen 2007 and it works great in shielded box. I modified it to surf pro and used flat coil and it works extremely good. Would be nice to reverse engineer original PCB, but original barracuda pi PCB was reverse engineered by you so I think barracuda is better project project. Send me a bara PCB and I will build new underwater detector. Also notice star ground lines. Use high quality components to keep noise low. Do not use cheap Chinese parts for your project. Some of them are bogus rip-off. This is advise for newbies.

For Chinese components first prize, I take note. Thank you dbanner and happy new year 2018 to all
