How many dig just a threshold change ?

[Cal_Cobra]

I read in the Sov manual that "Small or large deep targets may not produce a distinct target signal but rahter cause only a slight change in the threshold tone."

I seem to hear that all the time when I'm hunting, has anyone had any luck digging these threshold changes ? I guess if your in an area void of trash it might be worth a shot, but in parks I seem to hear the threshold changing a lot of the time.

These are something you learn from experience with the Sovereigns. As you see the threshold changes quite a bit many time on each swing of the coil, but what we listen for when going real slow as this is where the depth comes in with the Sovereign. We may only hear a slight positive threshold change and not a normal signal like a coin not as deep and we will work these signals with the Sovereign wiggle and see they are repeatable and sometime hard to get the tones and meter reading trying to climb as they are so deep, but you will see they sure are trying to though. These are the ones we want to dig and sometime we may or may not get a signal in all metal, but we know there is one in disc as we heard the threshold tones changing. Like I say much of this will come with experience with the Sovereign and not something you learn overnight.

I do at the beach when using the sov, but will usually check the target in all metal mode and make sure its a target and not a patch of black sand or something that could also cause a threshold change.

I played around with this last night. Their tearing up part of our original old town area to install new street piping and dumping the dirt close by, so I spent some time hitting the dirt dump in hopes of finding old coins.

It's definitely something you need to exercise with patience. The dirt dump was pretty clean (remarkably clean actually) and on the threshold changes, I'd slow down, sweep a few different ways around where the change took place, and in a couple of instances I started to get a semi-repeatable climbing tone. I'd scrape off some dirt, and the signal would get stronger, until twice I did find a coin. Unfortunately they weren't old, but it proved a good technique. In an area with little trash were you know there's a chance of good targets I could see this being a valuable tool, on the flip side when I went to the park with a fair amount of trash I think one would go crazy trying this
