Sov. GT & Threshold

[Tony N (Michigan)]

I am curious about the threshold on the Sovereign GT. Yesterday when I was out with mine I could hear the threshold but if I would move the coil just a teeny bit it would disapeer. Then I'd have to wait for it to come back?

It seems that as I am swinging with my disc set to zero and the other knob set to zero that my threshold is constantly disappearing as the coil is moving, be it ever so little a move. Is this because there is a lot of iron in the ground (not necessarily nails but iron mineral?)

Does one need to constantly be hearing the threshold AS the coil is in motion unless one goes over a disced out item in order to hear a deepie?

its either the iron minerals or deep iron trash. even with losing the threshold sound the good targets will still sound off. i think some one later said that too high sensitivity will also cause this.

Yes thats why, the sovereign see alot and the slightest bit of iron will make the threshold disapear, be it small bits of broken nails or just nasty irony soil, this is way common and drives me bonkers, these are the places you need to slow down espically if they are proven spots that you know contain ''the goods'' , what will happen on a real deepie is the threshold will disapear then come back the key is listening to the pitch of the threshol when it comes back , if it comes back higher than normal chances are it has likley passed iron but if it comes back nearly the same thats when you need to ''size up'' the object,I check to see if the threshold is only disapearing in a tiny little spot and if it is you can go to Am and see if its just a zing or a full blown loud sounding wail , You need to be hearing that threshold constantly and when it leaves wait for it to reset, if its constantly nulling (like almost everywhere I hunt) go super slow and just keep hunting its a bit frustrating but once you get used to it those spots can be very rewarding , and some just suck so bad you wont wanna go back, I have hunted places where the sovereign constantly nulls using other machines and if the machine doesnt mask the iron all you get is tons of little blips, Iron sucks and the sovereign really hates it bad........

With the disc set to 0 and the notch to 0 the only thing that will null is iron as the Sovereigns hates iron, but the bigger pieces may give a null and a quick high tone of a good target. Now this is what we say if your sensitivity is too high as it will null more and longer missing any good targets that is deeper. The threshold should null and you should hear some tones come and go too, or you are swinging too fast, or sensitivity too high. Try something if you will when you notice a lot of nulling in a old area. Stop and stand still and now sweep the coil very very slow and see what you hear,Maybe go back and forth on the same spot trying to hear anything but a null. Can you hear anything but a null?? If you do drop the sensitivity lower and see if you can hear anything other than a null, just remember you can not go too slow with the Sovereign as it will see it if it is there, but if it is nulling all the time it will be hard for it to see a deep target.

If I turn the sens down to around 3 o'clock the threshold is pretty constant.
And, if I go into auto sens the threshold is pretty constant.

But do I lose a lot of depth doing that just to keep my threshold?

I buried a quarter at this place about 6" deep to see what kind of response I would get and it was kind of choppy. So I went into all metal pinpoint and noticed above the quarter and a little to the right was a u-nail. But I was still picking up the quarter, though, as I said, it was not a perfect sound. When I removed the u-nail all was perfect.

This was a rather serendipitous, fortuitous event (I like those big words) as I now know what a coin sounds like mixed in with iron.

Adam, when you say "You can go to AM and hear if it is a zing or full blown wailing sound" do you mean go to All Metal and PINPOINT to hear these specific sounds? What if it was a silver dollar and you heard a wailing sound? I think a silver dollar would have sounded good like a lot of those iron nails? Maybe I'm wrong.

Maybe a coin would have given a much rounder, fuller sound in disc?

I'm just trying to learn this machine.

I know when I had my Nautilus it could tell you an iron nail by the length of time it took for the signal to get to the middle of the coil. You could actually hear the signal begin before the edge of the coil got to the nail in one ear and in the other ear you could hear when the nail got in the middle of the coil. Whereas a coin would give both sounds pretty instantaneously in both ears.
