Sensitivity settings. Is there any relation to the setting and power required from the battery? In short, the higher the setting, the more drain? At some point, I think the gain drops off...I have a Silver U Max, run it at 6, and do not see where setting at 10 makes a depth difference that can be noticed. Is there a sweet spot. for discrimination and sensitivity?

You're probably running it at the right level. When your detector becomes unstable then you're to high. Turning it up does not drive the signal deeper into the ground as many erroneously believe - it just makes the coil more sensitive to the target you hope to find but it also makes it more sensitive to everything else in the ground including mineralization and can mask many a good target.

I experimented w/my Silver and 6-8 seem to be about the best HIGH settings. However, I rarely set mine above 4-5 as per what Uncle Willy posted, because I'm usually at a schoolground, park or some other newer location. If I were at an older location w/possibilities of older targets, I would probably set it at 8 and scan much slower than usual to give the Silver time to recover from any ground signals. Since it STILL goes deep at a slow scan (try it and see) you can "gain" depth by getting a signal where otherwise it would probably just blip or crackle out.
I run my sensativity as high as I can and still hunt smoothly.
It has little to do with battery drain and depth of detection.
I do believe it makes the responses more sensative. That's
why I do it. Also, I find, and like to find gold chains. If you
like small gold, it's probably a good idea to keep it set as
high as you can. ( Recomended by Monte )
Funny, Lots of folks say keep it at 3, 4 or 6. But you
should set it for the ground conditions you are hunting in.
That's why it's there.
I learned this from Monte, and it works for me.

Depending on ground conditions and junk high sensitivity can mask targets but as long as your machine is stable you can bump it up some. Many think the higher you set it the deeper the signal goes into the ground. WRONG. It just makes your coil more sensitive to the targets you hope to find but it also makes it more sensitive to every piece of junk that ever hit the ground plus the mineralization in the ground.

I had a place where I use to take my new MD's to check them out.
It's in a big old park with some history. It's a real trashy spot and is
a place where there is a good chance of finding goodies. Kind of
unknown by most MD'ers around here.
I had used a BH, a Garrett, a Fisher and then a Cibola. I found stuff
with all of them.
I got a Silver Sabre uMax and expected it's controls to be a lot like
the Cibola. They both have the same knobs and red a button for pin
pointing.
I dug a small brass bell that was real deep with the SS uMax
and
then I got another signal close to the 12" deep hole I just dug. I dug and
dug. kept getting a signal. The hole got really big and the 12" hole became
part of the hole. Before long I had a 20" X 30" hole I could stand in and
still kept getting a signal.
I decided to check it out with my Cibola.
THERE WAS NO SIGNAL AT ALL!!!
That was the day I realized that the setting on the sensativity must be
set for the conditions. I proceded to learn to put my sensativity on the
edge, but not too close.
Sense then, I have learned even more in the field and on these forums.
For that, I thank you all..........

Yeah that sensitivity is tricky and can drive you batty.
