LOOKING FOR GOLDSCAN 4 Schematic.

[tuntunlin]

If you have a clear photo of your board with the ICs mounted and everything looks correct, it seems like you might be using a counterfeit IC.

Greetings, Emerson Paz.
I would like to ask you with respect.

After you have fully built your GS5 Lite, could you please share your data and results as well?

I would like to know: does your unit work well across the delay range from 10µs to 25µs, or does it only work at a specific fixed delay setting? Also, does the ground balance function properly throughout the 10µs to 25µs delay range?

I would also like to know what frequency and pulse width settings you are currently using.

Additionally, after the ground balance rejects hot rocks, have you observed any improvements in target discrimination and sensitivity?

Please kindly reply. Thank you.
