Yes SURF PI discriminates small (little) gold.

[kt315]

if you will teach the surf to discriminate... you will be a winner and get Nobel Prize, Maikl. try... for begin ask Mrand how he built hibrid PI-VLF. it may be to give you a base.

kt315 you do not understand what I say. Surf PI discriminates (rejects, does not detect ...) fine gold but there is no problem with small iron. I think Mrand little angry with you...

Good question Homefire

Think the extra 'line' U8-Q4-U9 etc. is a extra 'window' that has a long delay in seeing at the detection signal, it only detects large 'late' metals.? so no gold anymore
But if so ..it can be useful .. if the extra channel detects .. you know you have large iron
Just a guess
