The best I can offer you is to detect in Zero Disc and spend some time setting your sensitivity to where it sounds off on the ground then backing it off just a bit. The 400 was not really designed as a gold detector but that does not mean that it will not work. You just have to get it to the ragged edge and be willing to dig every target. If you start getting a lot of ghost signals (dig and nothing there) you can try backing off onthe sensitivity a bit more.
Do not use Disc
Do not spend a lot of time using the meter. If it makes a sound dig it.
Good luck, hope this helped some.
