Disc. Or Notch. Better Wording In Question.

[Rrnp]

On the Deus 2 if I don’t want dig anything below VDI 30 and don’t want to hear iron what is better, discriminate to 30 or notch till 30 and turn iron volume to 0. Will the detector find things the same that are above VDI 30?   I know I will miss things that might come in below 30. Thanks for the previous post.  With this wording hopefully my question will be more clear but the other answers helped me a lot. I don’t know if I should have posted this on the previous post or started a new thread.

Disc is a target signal processing filter.  Too much can adversely affect performance including depth and separation.   XP sets the defaults for disc between 6 and 10 to provide optimum iron filtering and stability with respect to the ferrous/non-ferrous horseshoe display.  I never recommend pushing disc higher than the top ferrous range (typically 10 but non-falsing ferrous can show up between 10 and 15).   I also recommend utilizing some disc filtering for Horseshoe display reliability and to mitigate ferrous down averaging (disc set at 7 or 8 works well).  With the Deus 2 iron volume feature you can still hear ferrous targets if desired so you can locate iron patches or to have total target awareness while still reaping the beneficial effects of the disc filter.  This is one of the downsides to full tones...no iron volume so you can't apply "normal" disc (e.g.10) AND listen to the iron.  So in full tones, I set disc between -2 to +2 to quiet things down but to still let me hear some iron.  Anyway. I digress.

Notch is an audio only filter.  It does not affect signal processing or performance. It merely mutes audio associated with targets that have a TID that falls in the range of the notch filter settings.  You can set up to 3 separate notch filter ranges (or just single TID ranges) of your choosing.

So if you don't want to dig anything below 30 then just don't dig anything below 30.  If you don't want to hear any targets at 30 and below, simply set a notch that encompasses the range from the highest disc TID setting (e.g. 10) to 30 and be sure to set iron volume to 0 so you don't hear the discriminated iron that will otherwise sound off below 10.  I recommend leaving disc intact because disc helps to mitigate ferrous down averaging of non-ferrous targets in the vicinity of iron targets as I mentioned above.  HTH GL HH

Thanks so much Chase, perfect for my weak mind to understand. I went out today for my third time with my Deus 2 and found a 10k 1.36 gram gold ring. VDI 49-50😀. The Deus is going to have a long learning curve for me.

Congrats!  I just got junk bling on my recent beach trip, but it was fun and I learned a lot about the D2 and the inadequacies in my scooping technique in rough surf.

Pinpointing and scooping in rough surf is a real challenge for anybody...including experienced beach hunters like me!  At 74 however, I don't do rough surf anymore. Tame oceans are my friend these days!!!  😃
