  1. Based on Tn's testing, other reading and quotes from XP folks like Gary Blackwell on other forums, I think I have pieced together what this Ground Sensitivity thing is doing. First of all we need to take a look back at what XP was trying to accomplish with GB tracking. This is speculation because XP does not discuss much about secret sauce, but I believe prior to version 4 software, XP executedGB tracking as a time based feature. In other words, while in tracking XP simply periodically measured ground phase reading and adjusted accordingly (say every 1.0 seconds). This had the unfortunate drawback of cause ground phase reading to abruptly change when you were swinging over a ferrous target that had a pronounced effect over the localized ground phase reading and resulted in the dreaded disappearing target trick, wherein the target would simply disappear if you swung the coil over it enough times while in tracking mode provided the target affected the local ground phased reading (e.g., large iron target or hot rock). To solve this problem, I believe that in version 4, XP decided to use ground mineralization index as a trigger point to initialize a ground phase measurement. Changes in subsequent mineralization index readings above a certain threshold would initiate a new ground phase reading. The problem with this approach was that in highly mineralized soils you could get large swings in mineralization index which could result in unstable ground phase readings. In an effort to fix this issue, I believe, XP in version 4.1 implemented a user adjustable ground sensitivity setting that determines how much of a relative change in mineralization index needs to occur before the Deus takes a new ground phase reading for tracking purposes. If the sensitivity is set low (e.g., towards 1) then a really significant change in mineralization index needs to occur (think of this as a large spike occurring on the mineralization bar graph meter before a ground phase reading is taken for tracking purposes. If sensitivity is set high (e.g., towards 10) then only small changes in the mineralization index need to occur before a ground phase reading is taken for tracking purposes (think of only a small blip change in the mineralization bar graph changing). So a 10 setting would be good if you wanted ground tracking on dry white sugar sand beaches with little mineralization and little change in mineralization and a 1 setting might be good in Culpeper which has high mineralization and large swings in the index. What is unknown is what threshold change in mineralization is required for each sensitivity setting, whether the effect is linear, whether the magnitude of the mineralization index and not just the change in the index has any bearing on what you should set ground sensitivity (i.e., is it a percentage change in the baseline reading or an absolute change), and, finally, whether positive AND negative changes in mineralization index are tracked or only positive/increasing (or negative/decreasing) changes. We do know that if a change in mineralization index above the threshold is not sensed for 7 seconds, ground phase defaults to 88 (this might happen, too, if the coil is stationary for greater than 7 seconds). From reading information from a variety of sites and forums, it seems, according to Gary Blackwell, that XP had the version 4 software set to an equivalent ground sensitivity setting of 10 (!). Also, Tn's testing has shown for some reason that the effect of the ground sensitivity setting seems to be less pronounced when using the HF coils. Strange... (note that the HF coils are not "updated" when the version 4.1 update is applied to the Deus). Bottom line, if you want to play it "safe" for most circumstances and soil mineralizations, using the default sensitivity of 6 is a good start (anywhere between 5 and 7 should work).
  2. Equinox And Monty's Nail Board

    To me the Equinox is like having simultaneous multifrequency on the Deus, if recovery speed is actually in the same ballpark as the Deus which it appears to be. With the Deus HF coils, you can still push the Deus above the maximum frequency of the Equinox which may afford some advantages in specific situations and of course the Deus is more compact to travel with and still only 67% the weight of the Equinox. To compete, Deus needs to come up with its own version of Mult IQ and really Minelab has cornered the market on that innovation both in terms of patents AND optimizing the feature.
  3. Why So Many People Not Sure Of The Equinox?

    Yeah, I figured it was an early "prototype" coil. But gotta keep those conspiracy theorists busy.
  4. Why So Many People Not Sure Of The Equinox?

    Anything we should know about the white colored coil on that Equinox, Steve? LOL.
  5. Why So Many People Not Sure Of The Equinox?

    Apologies for quoting myself, but with respect to the Deus vs. Equinox argument (or CTX vs. Equinox, for that matter), I think a valid point could be made that my perspective for the above is that with the exception of the Impact and CTX which I just mentioned, I have or presently own all of the above detectors. If I did not already own a Deus, and purchased an Equinox and it lived up to its promise, would I run out and buy a Deus to compliment it? That is a key question. I am thinking, at this point, no. Same thing regarding a CTX. Even knowing they are likely complimentary to the Equinox (i.e., superior to the Equinox under some specific circumstances), it would need to be a very compelling gap before I would pony up the $ to purchase either of these high end detectors on top of the Equinox. In other words, asking those already owning a Deus or CTX and who are thinking about getting an Equinox if they would then get rid of their Deus/CTX would be quite a different answer than asking those who presently own neither and who are getting an Equinox if they would then buy a Deus/CTX (unless selling the Deus/CTX was necessary to make purchasing the Equinox viable). Just because someone answers "no" in the second scenario does not mean that they do not necessarily consider the Deus/CTX complimentary to the Equinox. It is a nuanced argument, but an important aspect to consider, IMO, when discussing the concept of the flagship detector. It certainly should not be something that should generate hostility among existing CTX owners or those who are contemplating either the CTX or the Equinox. Similar to the point Steve was making earlier, I understand that folks are uncomfortable with the whole Equinox vs. CTX thing because most people look at the Flagship detector as the detector that encompasses all the features of it's lesser cousins, an evolutionary paradigm. Using the evolutionary metaphor, I think of the Equinox as a parallel branch off the multifrequency evolutionary tree, and as such it cannot hold up to a pure apples to apples comparison with the CTX or Excal or eTrac etc... (that is somewhat borne out by Minelabs own multifrequency evolutionary technology charts). The thing about the Equinox is that it is ALSO fast and light weight and that makes it truly "disruptive" tech as is the popular term for such things whether you are talking cell phones, laptops, virtual reality headsets, or automobiles.
  6. Why So Many People Not Sure Of The Equinox?

    Hostility? Seriously? Are we talking about human rights or metal detectors? Actually, I think I can make the same argument for the Deus vs. the Equinox. In my opinion they will compliment each other. I can see myself using the Equinox under many situations (definitely over the Deus at wet salt beach hands down and possibly over the Deus in highly mineralized soil for relic hunting, we'll be testing that this spring). But I still see situations where the Deus with the small elliptical coil may be the right choice over the Equinox for both accessibility, weight, and the fact that I can operate the Deus at frequencies higher than the Equinox can achieve. I think less of a "complimentary role" argument can be made for detectors such as the Garrett AT series, Whites MXT,/MX Sport, Nokta Impact, and Fisher F75 (except for coil choice) and similar First Texas detectors vs. the Equinox which appears to eclipse those detectors across the board.
  7. The only drawback being that while you can run the Equinox while charging, you typically cannot run BT headphones while charging them.
  8. In the other APT X headphone thread are some links to $30 US sports style (i.e., moisture resistant) APT X earbuds. They are not bank breakers, but you should definitely look for APT X vs. run of the mill bluetooth earphones to avoid lag.
  9. Equinox And Excalibur Power Bank

    That is actually a GOOD idea based on anecdotal stories of corrosion causing battery drain and damage on Deus coils where the charging terminals are exposed to salt water. Some folks have used simple electrical tape solutions, but the magnetic protector would be cool (perhaps with a lanyard if it gets accidentally bumped in use or in the surf).
  10. So What Is Gold Mode Exactly?

    Ditto. You have received several "Trophies" from me. I feel almost like I've already been swinging the Equinox based on the info you have provided here.
  11. Equinox And Excalibur Power Bank

    Folks if you are spending 12 straight hours in the water, might need to take a break for lunch (and you can recharge then) but don't go back in too soon so you don't get a cramp. Lol. Seriously, if you charge up your battery pack fully b4 your hunt, it should basically last you ALL DAY unless ML botched it. Should not have to rig up an in water charging solution. If you are not in the water you can also charge on the fly, but that should be a rare necessity. This is based on my experience with the Deus where I have to worry about FOUR LiIon batteries (coil, control box, headphones, and pinpointer) and it has NEVER hindered an ALL DAY relic hunting session like a DIV for me.
  12. So What Is Gold Mode Exactly?

    Steve - thanks for the tip on the user profile button. That is a great feature. When I am using a Deus I like to "interrogate" the target using both tone and pitch modes at different frequencies and this can easily be accomplished using the +/- buttons on the Deus remote. Though not as flexible, having the user profile button will enable a similar approach with different "modes" of Multi IQ. Regarding Gold Mode VCO, similar to but not as responsive as Gold Field on the Deus but I see it can be a useful tool for more than just nugget hunting. I take it that VCO cannot be selected as an "audio tone" choice for any of the other search modes - only Gold Field? Finally, after viewing your video, and listening to Lunk's discussion of how the detector was set up when he had the chance to swing it at the conference, it really sounds to me that he was NOT in gold mode. He seems to be describing the Park or Field tone. But you would know best having actually swung the Equinox. I guess the only way to know for sure is to have Lunk weigh in on which of the tones most closely matched what he was hearing when he got to swing the Equinox.
  13. My First Equinox Gold Nuggets

    Sounds about right. And I guess soneone else has $600 to spend towards a new Equinox. Win-Win!
  14. What Are Aptx Low Latency Headphones?

    Those are the ones I have. Just waiting for an APT X comoatble metal detector to testvthem out on. Anyone know where I can get one?
  15. That sounds more likely than the oddball configuration I was postulating. What's cool is, if that was the case, that you were hitting on such small targets and could pick up the gold test target just fine even when you were not in gold mode! It's intimidating to be handed a machine cold and then swing it when you are not intimately familiar with the user interface. It's almost a little like flying blind (or when you swung a metal detector the first time out without out knowing what all the adjustments actually do) because its hard to pick up the visual clues of your selected mode off an unfamiliar screen. Until you are used to the icons and layout, it just looks cluttered plus you are mainly focusing on the audio and target id when you have such limited time to play around with it.
