Notch on Deus,,,,using it can help you here,,,,but you just don't notch out targets by exact vdi,,,,you have to go higher.
This will not get some silver or higher conductors though.
You need to be thinking,,,average TID here,,,,,,leaver the lower meter vdi stuff alone,,,watch for mid level meter readings,,,,,tab near coin for example.
You can also notch out 00-90 and have a run,,,,you won't hear much tonally,,,deeper should come through.
Experiment with different freqs.
When you do get a mid level TID target reporting in,,,,walk a circle around it while,sweeping,,,see any monetary spikes of TID number?? If yes dig it out.
Try and be able to tell,,,,,using all means possible,,,is a target that is being tonally reported,,,,,is it a solo target or a nonferrous combined set of targets..
Also,,,,you might consider digging what I call challenged only targets with iron and nails,,,,these likely will have meter read is between 00-07 on the meter,,,even if running 0 Sid.
Lots of ways to approach and do.
Use the Deus detector tendencies,,,key on them,,make them work for you.
