I want to be clear I was doing very good using Auto even though here in my ground rarely was Auto+3 usable. Most places Auto+3 produced a Null whenever the Coil was moved. It did not matter how fast or slow it nulled out. I was dropping my Auto settings to get a good threshold and finding a lot of coins.
I know it was an air test but changing to manual increased detection on a dime by two inches instantly. This stuck in my mind.
I went out yesterday with a low 22 manual setting and increased my depth and I really did not get many false signals, Most of the false signals I got were highly suspect before I dug them. One was a can way down there.
With the higher manual settings I got the same nulling that I got in auto which to me is
A Nulling over Iron
B Over driving your machine
You have to be able to tell which to get machine to run correctly and ID. Remember that good signal that will not ID until the coil stops and the threshold returns.
Manual is a pain because you do have to adjust it to get maximum depth and it has to be low enough to allow your threshold to bump passing over that iron.
It could be much worse you could be running a V3i where you have a bunch of settings including ground balance that are constantly needing adjustment.
I run pretty good discrimination all the time (Park Pattern) except I open up to Ferrouse 23 so I really have to pay attention to make sure those nulls are not bad targets, and the only way to do that is pay attention to the threshold.
Really something to this Manual Sensitivity so if you are not running it know you are cutting out at least 2" or more of depth.
