Vanquish 440 Question

Hello...I'm currently using the Vanquish 440. Not sure if many know this but this thing has unexpected depth capability and can find extremely small, some would even call specs, of metal. Which is part of my question/problem. I am gett very strong mid tones which turn out to be extremely small pieces of metal that even my pointer can't find. I'm upgrading to the Equinox 600 soon but I was wondering if there was any way to cut out signals from these tiny pieces of metal. I'm running jewelry mode (iron cut out) with sensitivity maybe a little over half way. So tired of digging these great sounding mid tones only to find (if I can) specs of metal.
