Hello to all. New here and have been using the Tarsacci for only a few weeks, but it has quickly become the favorite detector ever. So many questions though.
Some have recommended very high ground balance numbers, even in mild ground, to unmask targets. It is commonly recommended to bump up 20-30 after ground balance by others. Saying commonly is misleading, there is a only a relatively small body of good info on Tarsacci in use and theory at best, and most of that is right here. Understanding is helpful to intelligent use, so it seems prudent to ask and see if there is something obscure being missed. Locally, there seems no advantage to doing either, and the detector seems fine at a simple ground grab.
High salt balance seems helpful to the point of being virtually set it and forget it (like black sand on) here. It is hard to understand why. Even so, these things just work. Low threshold and low sensitivity are also useful more often than not. Previously, running detectors hotter worked better, but not now and not with this. The Tarsacci seems just as deep and just as sensitive to small when run cooler. The only thing running hot seems to do here is make trash sound better. Running it a little closer to the lower limit seems to make it easier to recognize trash. Good targets sound good, and anything that sounds iffy usually is not. Possibly some things are being missed doing this but based on what is being pulled, that seems doubtful.
Even if it does not necessarily make sense in terms of ordinary detectors, it works like a charm. Mostly a person can hunt by ear and dig very little trash compared to most detectors this sensitive. That alone is a timesaver that allows much more ground to be covered per hunt. A cheap ($25) sling type harness was required to hunt land with the MDT, that epoxy coil out of water is heavy and unbalanced otherwise. It is a good compromise to get this kind of performance, there is no going back now.
