Terra, the war nickel was about 4" and was a nice 56-58. As has been mentioned on another thread, I, too, have dug some quite deep nickels with the Omega, F 75 and the F 75 LTD that the vdi's were quite a bit higher then normal nickel readings, but in the bouncy numbers there was enough nickel reading numbers to think it could be a nickel. Also, on certain sites, a lot of us will dig some of those bouncy, iffy, kind of off the wall readings. Doesn't always pay off, but when one does it makes digging a few worth while. mud, when ever I can I run as high of sen as possible and that is most often 99 with 1 disc with the Omega and I never use notch. I've never run sen lower then 70 or so with the Omega, so how much more depth I might get at 99 is an un-known to me, but I assume I'll get a bit more, at least. Mainly, though, the audio is better for me, a tad louder on deeper targets and seems to be more clearer and distinct. However, if a site doesn't have the potential for silver, one probably won't find any regardless of settings. Thanks again everyone. HH jim tn
