Just need a voltage limited 1A CC PSU (LM317?) and you can read "ohms" (which would be milliohms) directly on your 200mV scale, if you have 20mV, even better.

Trick is not to have to send 1A through your circuit... could get toasty, but if it's a short, you probably don't really care anyway...

I think you'd need the compliance voltage-limited to say 0.2V to not damage anything. That pretty much rules out the LM317, have to use an op-amp and power transistor.
I also do well with a good bench multimeter reading uV, using lower currents. You inject a current and can follow the voltage drop to the high current short. Or use a thermal imaging camera.

I have been waiting for this to become available, but I admit, I'm starting to lose faith.

Looks like a similar idea to the Leakseeker 89, just with a display instead of a row of LEDs and sound.
