Hi ghound, not quite sure what your result was when trying it out??ghound wrote:https://youtu.be/u34hA03W268
I read once that the Credo didn't pickup small lead like .22 pellets and so could/would miss small hammered, so i tried it out with the 13" coil @6khz, 2 tones set to small nails.

Thank you ghound for sharing this info. It is important that users come to this conclusion on their own since most of them do not believe some of my statements.ghound wrote:Many people are put off with large coils and low khz because they might miss small hammered.
It was to show that the Credo does miss the lead pellet and other small items but it still gets the tiny Roman coin in 6khz, probably also why it runs so smooth with little falsing.
A higher khz machine with a smaller coil would probably hit all the items.
With the Credo and all of the other resonant tuned Nexus models the sensitivity to small items at low frequencies is due to the electro-magnetic resonance of the receiving coil.
I have explained many times to many customers that when a coil is tuned in full resonance it does not require high frequencies to hit well small non ferrous targets.
With the Nexus Standard MP the difference between sensitivity to tiny trash and small hammered coins is much greater, regardless the absence of a resonance in the RX. The result there is due to the SDT - Super Dumping Technology, the electronic circuit responsible for better suppression of ground interference, which happened to suppress also the tiny lead trash without affecting the small hammered coins.
