Aren't there metals that are undetectable/less detectable, like titanium or even stainless steel?

No, it doesn’t work like that in the modern world. The nature of the materials are pretty obvious to a remotely competent sensor.

You can detect nonferrous metals by inducing eddy currents in them, then they become magnetic.
