Some things I learned at a Deus "Bootcamp" hosted by Andy Sabisch at Gettysburg this past weekend.
Version 4 Stuff:
Andy went into great detail on Disc versus Notch. I posted that info in another thread but to sum up -
His opinion (not necessarily mine) is that setting Disc at 0 (or any setting less than 5) does not maximize depth and only tends to cause the horseshoe display to be unstable and unreliable. Not sure this can actually be proven. But he did demonstrate that depth detection capability on a deep coin does not suffer until you set discrimination well above 15 or so. That means if you have some reason to suppress signals from 0 up to a relatively high TID setting (e.g., 15 or greater) then it is best to use notch because notch just suppresses the signal in the given notch range and does not have any effect on signals outside of the notch range(s).
He is not a Full tones guy so his other reasons for keeping Disc in the 5 to 10 range don't really apply to full tones, but for multi-tones (2, 3, 4, or 5 tones) audio, if you set Disc to 0 (or you use notch instead of disc) you lose Iron Audio capability. You also lose your first tone break in multitones. Basically no difference between Disc and Notch if you use full tones as long as you don't set Disc too high (i.e., above 15) or too low (i.e., less than 5) for full horseshoe functionality, reliability (according to Andy - hard to really prove one way or the other).
He confirmed that the Pinpointer will not be as sophisticated as a Sunray probe (i.e., no discrimination, tone ID, or TID will displayed when it in conjunction with the Deus). Disappointing but there may be hope for the future.
He confirmed that TX Power is locked at "2" for the high frequency coils (vs. locked at 3 as is done for the existing coils when operating at 4 khz - this is another annoyance since 4 khz maximized depth but Tx power at 3 is not good in highly mineralized soil).
He hinted at some future untapped functionality for the HF coils in a future SW update and then all joked about a release date for Ver 5 with Alain from XP (didn't seem amused, or could understand what we were on about) and Gary (who laughed).
Field session in Gettysburg (private property of course) was fun. Found some modern US and foreign coins and found a .635" period dropped lead round ball projectile.
Probably some other useful info I did not remember to cover will supplement this when I get a chance to go over my notes again.
Cheers.
Version 4 Stuff:
- Final public release version is set for this Tuesday (3/14)
- They unfortunately did not fix the Reactivity/Silencer "default" setting bug/feature, even when incorporating Reactivity 2.5. So whenever you manually change reactivity, you still have to go in and make sure silencer is reset bat to -1 (off) or 0 (max setting that does not affect depth). I personally prefer 0, but that is not a default setting for ANY of the reactivity settings.
- They improved GB tracking to not lock onto trash ground targets [Good!] but did not include GB bias offset in tracking (e.g., set up GB to auto track to a fixed +/- x clicks from the measured ground conductivity reading, which would be a huge feature IMO to squeeze some depth out of the machine or lower ground noise)
- I asked Gary of UK Deus video fame directly on Skype how and why regarding ceramics (per the XP literature discussion on negative discrimination) and he said that UK detectorists would use the negative Disc setting to enable them to see increased concentrations of mineralized bricks and roof tiles in the ground which would be indicative of an old dwelling. Andy chimed in that you would def pick up bricks with negative disc
