Any verdict on notch and depth

I've read some saying notch dont affect depth,,, and the same saying it does.
They are older threads so I'm thinking maybe now Somone has a better understanding of if it does?
I like notch on detectors, I'm a coin hunter and was wondering if the deus does lose a significant amount of depth?
 
You probably won't lose much depth but remember too that the Deus is not the best on VDI, even on shallow targets, and coins tend to jump around a bit even out of the ground held in hand. I've noticed that sometimes if you get close to a notch range - for instance if you have 58-71 notched and then you come across a target that reads 72, 71, 73, 74, etc. with every sweep you will most likely get a little "clipping" on the target since <72 is notched. Notching out the low ranges for iron doesn't seem to affect too much - HOWEVER - if you notch the mid and upper 90s YOU WILL lose those fringe non-ferrous targets sometimes.

Sorry for the ambiguity, but the VDI in my opinion is a little unstable - but I've learned to roll with it! If you get a soft, squeaky tone that sounds at least similar on a 90-degree cross-sweep...dig the target! You dig enough of them, and you will be rewarded!
 
Running at 12 kHz I want to notch everything to 50,then notch from 60 to 73 that way nickels and Indians should able to be detected,as well as silver...most places I hunt are really bad and old old iron as well as modern trash....basically 150 or better years of people and junk that I'm sure has been over b4. With many machines but I'm thinking there's goodies within 6 inches that the deus could see others couldn't...ive ran a at pro there and came up empty...ran a r2 and found some wheats but I couldn't run notch on the r2 and get any kind of a decent signal in trash...And it's insane running wide open,I tried it there,just fatigued in 5 minutes
 
Vdi sucks on this machine I run the unit in full tones and don't even look at the screen run it with zero discrimination set your reactivity where you want it and dig all repeatable sounds
 
I agree with CZ. Notch doesn't have a direct affect on depth per se, BUT it can make you miss deep targets if you are not careful. Using your example of notching out 60 to 73..... On a strong very shallow target you get a good hit and it shows a VDI of 74. But if that same target is say 6 inches deep, there is a GOOD chance that the Deus could ID that target at a VDI of 72 instead of 74 and you would therefor notch it right out and never know it was there. The deeper the target (weaker the signal), the less accurate the VDI number will be. Without notch you would easily hear that target, with notch you lost it because it was too deep for the Deus to assign it the proper VDI.
 
I would be careful of notching the 60 to 73. Here in So. Cal. I have found nickels and gold rings in that range. I usually run notch to 40 and then 98 and 99. Sometimes if I'm finding a lot of zinc pennies I will notch 84 to 88. I run in 12kHz while hunting with a 4kHz program to test for bottle caps. I believe I read somewhere that your notch should be 6 numbers from your accepted numbers to not lose some targets, but i'm not sure of that. Also, as a side note, I have found gold rings as low as 43 and as high as 85.
 
I'm gonna play around with the notch and see how it goes.im a coin hunter ,and like notch but I run wide open in tot lots..thanks for all the help.
 
It simply blocks the audio from coming through for signals in the range you have notched out.

Tested in a wide range of soil conditions and there is no impact on detection depth through the use of NOTCH

Coming in late to an interesting thread! So, apparently notch and discrimination use entirely different methods? Why ever use conventional discrimination, then? Why not just notch out from zero to whatever?
