Fisher Impulse AQ Discrimination Explanation


Recommended Posts

I think some might miss one aspect of Alexandre’s post above - If I am not mistaken each “row” in the diagram shows what is rejected when the reject control is set at a level sufficient to reject (mute) the size nail shown in that row.

“Look ‘Ma - no holes!!!”

Seriously, this “bending” of the time domain curve is new and seriously useful for beach hunting for gold!

Also - note very carefully - Alexandre’s illustration above is not theoretical - he has verified the data he presents with the actual targets he has illustrated in the picture.

Alexandre... Your chart is very encouraging! 

So... In All Metal mode 10K rings will be detected along with everything else.

By using some amount of discrimination, can 10K rings still be detected? 

Merci !

All these targets were found at the IMPULSE by me or Le.Jag
As a rule, I keep only the targets whose conductivity I don't yet have.

a little precision anyway
he found the nails
and me the gold rings

yes, the lower the carat
the easier they are to detect in discri

a large 10 k signet ring is easier to take
the same in 22k / in rejection mode

If the carat is low, it will be easy to detect in all modes.
If the carat is high and the jewelry is heavy (24K and> 4grs) then it will be difficult not to reject it and continue to reject ferrous in the same time.
