Dunno Bill, I gotta partially disagree on that. The conditions are too variable to just
leave at one setting all the time.
Sure, depth isn't everything, but I might as well get all the performance out of the
machine that it is capable of.
And being a ham op for over thirty years, I'm quite familiar with these type RF devices,
loops, sensitivity controls , etc.
The signal into the ground is fixed. It's always full blast. All the sensitivity does is
control the level of the receiver. If you run at "4" all the time, you will not see the
full depth capability of the machine in most cases. I've proven it to myself over and
over again on real targets.
It's like setting the sensitivity on a ham receiver to half way. Only strong signals are
heard. The weak ones are pretty much not detected because the sensitivity
is so low. It's the same basic thing on a detector.
I've found many targets running hot, that would not make a peep running at halfway.
I've tested it over and over just to see. It's not a myth.
And to me, it shows up the most on the largest coil. "9x12"
But...
I consider my method more for the advanced user. You have to know the machine
well, and be able to tell chatter from real signals. Which I can... So the extra falsing
really has little effect on me. But to a beginner, it could probably drive one to take up
golf..

So I agree with telling beginners to keep it down, but I think it's a mistake to etch that
in stone for more advanced users.
I think it's best to run as high as the ground will let you if you know the machine well.
And it's never the same, so my sensitivity setting is rarely glued to the same place.
I adjust it on the fly many times if the ground changes, or a place gets busy, etc..
Some places you can't run high. I know those places, and I'll crank it down.
But some places, like say up at my place in Oklahoma, I can run full blast most of
the time. I get no mineral problems cuz it's good ground. I don't have masking problems
because being empty land, there is not much there except for a load of ammo in the
ground. All I get by cranking it there is more depth. But I usually can't run that high
here in town unless I want to deal with the chatter. But I can still often run 6 or 7..
I'll have to admit, I almost never run at 4... :/ I'm losing depth which I'd rather keep,
needed or not.
Anyway, I'll agree it's probably not for everyone, but I stand by my methods if one
wants to scrape every bit of performance out of a 250. And I've seen a few others
that seem to run the same way with good results. But like I say, most that do are not
beginners at the ace 250.
I always let the ground tell me where to set it. Some ground is happy ground.. Some
ain't...
