I run the threshold at a barely audible hum with a good pair of headphones. That is usually at 7-8. You can actually get a change in threshold on very deep targets that are not strong enough to give a target response. You can test this with buried objects or even targets in top of the ground by raising coil while sweeping back and forth. At a certain height you will only hear a raise in the background threshold without a toned response.
