I don't want to ruffle any feathers here.
But if a user of Deus is using deep program and they are not digging any iron ever, they are probably leaving some good targets in the ground.
I can say this even about other program use on Deus, but deep program the odds for digging iron are higher.
As far as xy screen and using it to make dig no dig decsion.
Again if you use it to make your decsion you are leaving some nonferrous items in the ground.
I have recovered good nonferrous with shoddy xy screen data presented.
The xy screen is a guide only.
The tone presented, and the behavior of the tone are the real keys.
Agree even though I am a novice with the Deus and still learning I have made my self listen a lot more to the tone today using the 9 program XY screen . I dug lots of small iron targets that sounded good and were very deep they gave a scratchy signal on screen . dug one 88 ID target that had a nice clear tone and sounded to be deep after deciding to dig it it was deep and on edge a nice 1950 silver Washington Quarter . most quarters I have dug have been coming in at 93 to 95 . Not sure why ? on the 88 , I will say this I have done better using the number 9 factory program than any other so far . I think it makes me listen more to the tone . tried the Basic and just don't like it . The Deus fast is my second option . I know I need many more hours with the Deus to master it . Reading a lot of the response on here help me tremendously and I for one say Thank you to all you guys. one of these days I will figure out how to post pics again on here they keep saying file to large so I need to resize them
A lot of nonferrous the Deus actually detects ( provides tone/clues), are not always textbook,,,quite a latitude of what can be heard tonally.
Imo based on useage the elliptical HF coil extends this latitude for tone provided on challenged nonferrous targets.
