These two seem connected in a way, yet not in a clearly defined way. In fact, what threshold does on a Tarsacci is not clear at all to me. One more way the Tarsacci differs from other detectors. Low sensitivity and threshold settings work better in trash, and unlike some there is not nearly as much loss of depth or small targets as a person might be used to. Here, thresh -9 and sens 3 is often used when the ground is tough. It is surprising how small and deep it goes even at very low settings, and even in presence of trash.
In clean ground, it can of course be turned up, but there does not seem to be the big advantage to running hot to the point of barely stable as there is with some. Anyone got input into why this might be so? Do you run hot or cold and how do you decide what settings to use?
All of these threads are in aid of finding some metric to determine optimal. Less clear cut sometimes with a Tarsacci, but worth figuring out. It is of course personal preference in a lot of ways, but a rationale would be nice too. For me, the settings are determined by what seems to work best hunting relatively shallow in high junk. It is to limit it in some ways to make sense in an environment where there is too much trash signal that sounds too much like good target, For as long as aluminum looks like gold this will be a running battle, but playing with the concept is a joy.
