Raising Threshold during hunt

[Buried Crap NJ]

Anybody seem to see this happing? I start hunting and after a few targets the threshold gets louder from the the slight buzz I set it at. I posted a few weeks ago I could not get a smooth threshold in AM mode. It seems to be when I have freshly charged batteries?? b
Because the next day I was able to get it smooth. Tomorrow will be the second day out on the battery andI will see if I am able to hold steady. I get so worried about that dam threshold after have to send it in for repairs 2 months ago.steve

Besides a fully charged battery, I find that if I practice better coil technique and keep my coil as low to the ground as possible , it will eliminate a lot of noise and will also keep the threshold lower .... Sometimes I get lazy after detecting for a while and my coil will end up higher and at an angle at the end of a switng !!.....I look over and my partner exagerates my switng .....It helps to make me aware of what I'm doing ....Sometimes you trance out , and loose good technique ...

Ya I think I am not posing the question correct. What I mean is my threshold steady goes up as I find targets each target gives it a little more louder tone. I have to readjust it back down every few minutes. Get annoying to keep having to readjust it. I know I have to do it over the coarse of the day hunting different grounds as you move along. But I was doing it on my home court beach every 20 feet. Again I seem to have problems only on a fully charged battery?

I have noticed my Sovereign does this also.
I haven't noticed under what conditions it does this, but I have noticed it.
I thought maybe my headphone cord was rubbing up against the knob causing this, but not sure.

You will get the tone of the target that you hit as your threshold for a while after you hit the target ....In other words , if you hit a quarter, the tone will jump up to the high tone and will stay there or linger for a while ....if you then hit a nickel , the tone will drop again to the nickel and sustain on that tone for a while .....If you are not happy with that , you can turn your threshold down a bit and the sustaining tone will not last as long ....it will be more abrupt ....It's actually sustaining , but because you have the threshold turned down, you don't hear it ..... You are only hearing the beginning of the envelope of the tone with the Threshold turned down .... I'm not sure if this is what you are talking about .....You may also be going into higher mneralization which will seem to make your detector louder too ...

I am in the process of trying out something I read that Oldbeechnut is doing ....This is by adding an amplifier to the system and running the Threshold VERY LOW , and boosting THAT stage of the Threshold envelope ...It allows for very faint "whispers " to be heard in good soil where there are not many targets ....It amplifies the minor changes in Threshold and sometimes does not even give a noise except for the threshold change .....This will indicate a DEEEEEEP target that is otherwise not heard ..... I'll post when I get some results !!....( If I can find soil that is clean enough around here to test it on !! LOL !! ) ....JIm

My excal ll does that sometimes for the first few targets if its real cold out, i put it down to warming up of the internal components, usually after the first half hour, i get to the stable threshold(volume wise) it doesn't always happen just seems more so on cold days.
