In the parks in my town you are only allowed to use a probe/screwdriver to retrieve targets. In my case that means nothing deeper than 3-4". So, in order not to be tempted by deeper targets I set up a program to only go shallow. I named it Skimmer. Basically everything you do to get more depth, do just the opposite.....Sens 80-85, TX 1, disc 25, silencer 3, reactivity 5, freq 55, 9" coil. But it still hits deeper targets. Amazing how difficult it is to make the Deus not work well. LOL.
