Discrimination Question

Can someone explain discrimination on the Deus 2.   Why is factory setting at 10, 6.4, etc.  VDI number 30 on the Deus seems to match the Equinox at 0 ( I think). So why not set the discrimination to 30 on the Deus? Thanks

it is my "feeling" that higher disc loses depth. I do dislike how XP wastes all those lower TID's and jams them together at the higher ones. You could notch out up to 30 if you want and it won't cause dept loss if that helps ya.

The higher the discrimination setting the greater number of targets will register as ferrous.   If for example you set the discrim at 7, targets'TDI that range from 7 or below will  be reported as "iron."

Unlike other detectors Deus only blocks the audio which doesn't affect depth. The only setting on the Deus II that will affect depth is the Reactivity setting. This determines how long the coil stays on between targets.

The D2’s discrimination is similar to the ATPro’s in that it has a adjustable tone break on the size of the iron you want to disc out, or rather it has broad iron range. Let’s say your working on a site that has a lot of a specific size nail(s). You can adjust that broad iron disc just to point to where it breaks that specific iron up (tone break), not totally out, or whatever you prefer.

It doesn’t work like that in full tones.  See this thread:

A lot of times, a good target next to a small ferrous target can bring the VDI down.
 

 Example…a coin or old button that may read 7x-9x on its own, but next to an old iron nail it may read a solid 8 or 9.  If you run the discrimination up past the 6.8 range in Gen, and the 3 fast modes, you may miss a good target amongst iron if you’re just going by VDI alone.  (Park and Deep HC read a little higher so they could be bumped up a bit).  
 

vDI is a wonderful thing, but in iron sound is very important.  As is your willingness to dig!
