I like to hunt Pro mode, zero descrimination, 0% iron disc and iron audio off.
What I've noticed that you can identify bottlecap much easier with your front end of the coil in the trashy areas. Bottlecap under the front end is pure crunching, but if its a coin, sound just ends suddenly.
If you do the identification with iron discrimination and iron audio on, you hear the crunching sound with the sides of the coil which can easily sound like a good target and a trash nearby.
Also with zero discrimination, the deep targets sound much better. So you find deeper targets.
