Notching isn't an exact science with the Deus...I've found that if you have, for example, 60-70 notched out and you come across a signal that would read "67" it will still "crackle" sometimes. Seems like if you're within 4 points of the end of a notching area some targets will try to get through, and the effect is more pronounced the closer to the edge you get. A "69" or "70" reading will likely be detectable, but chopped. I've found some Indian cents this way when I first got started using the Deus. Was in an older area that was producing 1910s Wheats regularly and noticed some targets were crackly and close to the end of the notch window. Unnotched it and the audio quality screamed "COIN!" with stable VDIs although oftentimes lower than the Wheats.
Some Indian cents will indicate exactly like zinc cents, so notch wisely or maybe not at all and listen to the audio :detecting:
