Stupid newbie Nox 900 question?

[KSDfisher77]

Why on the Equinox 900 you lose your FE iron settings on single frequency of 4khz? I havent tried the other single frequencies yet, but on 4khz you lose your FE iron bias settings. Can some explain this? Or give me a anwser why they do this? Thanks appreciate you guys & gals.

I believe this question has come up before… Iron bias is only active in multifrequency mode.

Ok thanks. I will say when running in 4khz it's like they got a preset iron bias algorithm built into the 4 khz frequency.

I dug some deep clad quarters that had rusty bottle caps 2-3" above the quarter in the ground when dug. I had 3 of the 7 quarters I dug where rusty bottle caps were above the quarter in the hole & they Identified them well at 6+ inches in powder dry dirt.

That is quite impressive!
