Just a couple of comments/questions on your settings?
First let me say that there are no sure things in detecting and fewer absolutes, rights and wrongs, so if you've found a custom set of Deus settings that make you happy and deliver the goods, that is the most important thing (i.e., if it ain't broke, don't fix it). I offer the following up only so I can learn why other users are doing what they are doing and perhaps can provide some tidbits that others might find useful. I am not here to judge or say what I do is better than what someone else does and if it comes across that way, please call me out on it. So getting that disclaimer out of the way, a few questions:
Why are you not using discrimination but notching so high? Discrimination up to about 8 or 10 should not affect depth. Or put another way, why notch over discrimination?
If you can get away with silencer -1 (effectively silencer off) without a lot of chatter, that's great, but I've found you can get away with silencer 0 without losing depth so I never run it at -1 especially if I am using discrimination or notching iron and if the machine is otherwise chatty. Running silencer above 0 will defintiely result in reduced detection depth but may be necessary if noise is an issue (I would probably go no higher than 1 though). That being said, my question is does -1 provide some sort of detection advantage that you have been able to validate in practice?
Thanks in advance for sharing any of your insights on your settings.
