Threshold humm and deep silver question?

[grumpy]

I have a question about the threshold and it masking deep silver?
I have an SE and use it quite regularly now for about two years and before that had a EXII but it never occured to me that is it possible that the threshold humm will mask the deep targets like deep silver coins.??????
I run the threshold at about 1/3 up so I can hear it clear but not what I would call faint and I dont hear as good as some of you youngins do so is this possible that it will hide the hit of deep silver that are faint???
I never thought about it but does a target like a deep silver quater have to brake the threshold barrier before you will hear it???
Thanks for the help

Grumpy any coin/target has to brake the threshold to hear it, like you my hearing is not so hot either. Make sure you are using a good set of HP's like GrayGhost.

I am no expert but I thought that any target has to break the threshold......the threshold is the noise you will here when there is no target under coil.......and when a target gets under coil you will here threshold break and tid will take over. I also read if you have threshold volume too loud you may miss quiet breaks in threshold.....but if you have any discrim. it will break threshold but null as in no sound......and if you are swinging way too fast you will miss it completely......swinging way too fast while walking forward way too fast is what I mean......there is a sweet spot for the minelabs and fast has a different meaning then most detectors........so one has to figure that out for oneself......trial and error will determine volume of threshold, and speed of walk and swing......and all the other settings which you use.....the more work the processor has to do the slower you should go....it could take nano seconds or it could take a few seconds to respond....each area has to be determined as to speed and how detector is responding . There is such a thing I beleive as too slow and too fast....so if you are too fast and are too def and need high volume threshold then you may need help.or just settle for the shallow stuff.....Like I said ......I am no expert.....just trying to help with my 2 zincs worth. ......Wishing you luck!.......

Yes, deep silver would have to break the threshold setting. Just make sure you have your threshold as low as you can get it and still be able to hear it. I use audible threshold at times and other times I run just below threshold. I haven't been able to tell any difference in depth between the 2 settings but it may be different for others.

Your gain setting plays into that as well. If the signal isn't loud enough to overcome the threshold but your gain amplifies the signal louder then your threshold, you should then hear it. At a gain of 7, I can still hear deepies at 10 to 12 inches with my threshold barely audible. At a gain of 8 or above, my SE's turn the weak GROUND signals into falses and it becomes more of a hindrance. Interestingly though, I can set my threshold one point lower while using my Sun Ray Pro Golds head phones then I can with my Rats head phones and still hear it.
