Fooling around with the Threshold control some...

Still learning in house....maybe tomorrow I will get to take it outside for a walk <img src="/metal/html/lol.gif" border=0 width=15 height=15 alt=":lol">
In Disc mode. Had it set at 0 sensitivity, 0 discrimination, nothing notched, volume at 2, and started working the threshold control up from 0, to +1, +2, +3, and +4. Used my ring collection and a nickel to test it out, staying in the foil and nickel low/middle tone range. The 0 sensitivity setting still air tested at about 4-5 inches on the rings, except for one cheap junk ring that reads low on the foil scale. I discovered the reason it read so poorly was because it is not a solid round one piece ring. Its one of those child rings with the adjustable band.
The constant treshold tone starts at +1, just as the manual said.
At a 0, all targets responded with the low/middle tone.
At a +1, the threshold tone sounds and you keep the low/middle tone id. Low foil range targets start to fade, but the upper foil range and nickel range targets come in nice and strong.
At a +2, I lose the low/middle tone id per se, but have a pronouced threshold audio change for the upper foil and nickel range targets.
At a +3, the low/middle tone id is still gone, and the threshold audio change is very slight on the nickel range targets. By very slight, I mean that the targets that did make a threshold audio change sounded like deep targets. Foil range targets created no audio response.
At a +4, you lose all audio id assoicated with the low/middle tone and there is no threshold change on any targets falling within the low/middle tone range.
At this setting, all middle/high tone range objects responded fine.
NOTE...***This seems to be normal threshold readings as I can somewhat recreate this on my Golden uMax. Of course the Golden only has threshold in all metal, but I can eliminate a threshold response to the same targets by increasing the threshold setting.***
I want to repeat this test at sensitivity settings of 2, 4, 6, 8, and 10, just so I understand what takes place at the higher disc settings.
