Threshhold

[Anonymous]

I have heard that by lowering the threshhold to one or two settings below what is audible that you can hear the fainter signals better. Assumming that this is true (and please give some feed back on that assumption) why wouldn't it be even better to just turn the threshhold all the way down to 0? Obviously my goal is to make it as easy as possible for the fainter signals to get through and be heard.

I'm just guessing, but probably turning the Threshold too far down would actually begin to hide the weaker targets, just like nearby iron targets mask them. The (probable) reason being that the weaker targets would have to overcome the <i>silent</i> portion of the audio level before they could be heard at all, and no doubt many of the really weaker ones wouldn't have the strength to break into the audible area.

Never tried it, but would have my doubts about not missing things initially. the threshold tells you many things about whats happening under the coil. I would think running under audable levels might cause you to swing to quick in some situations and you might miss a deep one or one near iron/trash. At least with the threshold and your detector nulls, you know somethings under the coil, either disced out, iron or mineralization, telling you to go slower

I usually use a faint threshhold for that very reason, to hear the presence of nulled objects. It lets me know to slow down and concentrate. But this information came from Carl the Minelab rep at the GNRS so it naturally has me wondering about it's benefits. I am just trying to figure out if a faint signal would have to push harder to get through a 0 threshhold setting or a setting or two below audible.

everyone has there little preferences, I guess the only thing to do is try them and see if you like them. I guess next deep one I get I could try and lower threshold and see if the explorer sees it better or worse
