I began to notice, after a few afternoons detecting on semi-muddy, iron rich trashy soil, that my Fisher F44 wasn't quite as zippy and precise as usual, and was very unstable.
I suddenly realized that my coil was quite dirty and caked here and there with dried soil. I went home and cleaned it completely back to shiny like-new. Next time I went out with it there was a marked difference and improvement in its performance, back to what it was when I bought it.
The moral is, keep that coil clean. If it has dirt, especially iron-rich dirt, stuck to it this will blunt the sensitivity and confuse the discrimination circuits. If your detector seems jumpy or dull witted, take a look at the coil.
The nearest analogy I can make is trying to see precisely with a dirty pair of glasses. The coil is the "lens" of your detector, so it must be treated with that kind of care. If you don't have a coil cover, definitely get one.
