Jupiter is Only a Planet - I Want a Galaxy

Recommended Posts

Ok, let's perform a small thought experiment.

What if I walked out on my 3 acres or so of AZ desert with a truly intelligent detector. I would ground balance and "initiate a session". As I got visual, tactile or Aural feedback from the detector, I would imput the results of my "analysis" of the signal in terms of what I had observed, whether I thought it was just ground noise (low value assigned by the machine - simce I had no direct observation, but only an opinion to offer) or whether I kicked it out of the way, determining that it was a hot rock, or whether I dug and ID'd it (high value assigned to the data by the machine since i had directly observed something).

After a bit of this, the machine starts modifying its operating parameters to take account of the data it's gathering as well as the data I'm inputting. So, instead of me having to notch out .22 LR cases manually, it would do it for me after I told it what I was finding - and if I found more of them outside the limits of the notch, it would analyize and compare GB and other factors to compensate - likewise if I found a target in that "notch" which a broad-based form of feedback led me to question, it would "reconsider".

For gold, if I was lucky enough to find it, it would consider the reading for a nugget in the context of other current and historical (for that site) data and tune operating parameters accordingly.

oK, where and when can I Buy this and why does this make me sad that I'll soon be 68?

Do you plan on living to be 168 years old - that might be what is necessary.


The other thing is that loud surface targets like .22 shells hide and mask deeper gold. This summer I had my brother in law out with me and explained that to him. We were at a spot that produced some decent gold but was littered with .22 shells. I dug maybe 10 in a small area and then went back over it with the detector. There was now a fainter that was undetectable when the 22s were present. I told him that was what gold typically sounded like. We dug it and it was a nugget. If we'd discriminated out those 22s, that nugget would still be in the ground.


There is a place for discrimination, but in prospecting you need to be careful with it,

When my my knowledge, experience, skills and intuition are replaced by gizmoizm it will be time for me to leave gold mining to the "smart" people.

Perhaps you might try dowsing.

(No offense intended, I 'm just grumpy today)

At one Minelab meeting with an engineer I suggested the GPX employ automatic timings. In automatic ground tracking, the detector sets the ground balance based on the feedback from the ground. Why also can it not use those ground readings to select a probable best timing for the operator, and vary those timings as the ground requires? Well, it could. It just has not been done. Timings right now are a fixed function, but variable timings is possible. There is much that can be done with processing power.

What I want is less settings, less controls. I just want the detector to work. My ideal detector would have a power switch and nothing else. That way I can focus on using my knowledge, skills, experience, and intuition as a prospector to find the gold. That is what it is all about - I agree with klunker there. The detector is just a tool, no different than a shovel, and should be about as easy to understand.

No offense taken. My imaginary detector would use artificial intelligence to combine the kind of automatic adaptation Steve is talking about with an ability to accept input from the operator regarding what he observes, concludes or desires. Intuition and experience would be inputs that the device uses to function as a smarter "shovel".

If a patch is producing tiny nuggets and you want to find all of them, then the device will have to operate differently than if you expect and hope to find larger, deeper nuggets. No one combination (at least in current PI machines) can be expected to do it all. Up to now, the best answer has been the GPX-5000 and a collection of different coils. The problem with that is that the adaptive inputs are all from the operator - what timings and other settings to use - which coil to use.

A more intelligent machine would use data it gathered about the ground, the EMI environment and targets - including operator imput like absolute target ID by digging - to adapt its operational parameters to the goals of the operator and the environment.

If it were done well, it might indeed only have one button! Of course it would take 10 engineers, 5 programers and $100 million to produce and that only happens with Military equipment and mass market hi tech - which our gear sadly isn't.

Oh well.

 I'm sure the technology exist but the market is too small to invest the $ it would take to wrap it into a single detector.

I would like to see a detector that could be switched from  P.I. to VLF. with quick change coils and cordless.

 I don't disdain technology but so much focus is aimed at technology that we  are no longer willing to invest in the hard work it takes to learn basic common sense skills.

 My vacuum tube Heathkit detector is nearly completed.

      THIS !! All the people boo hooing will be in line to get one at that price point. It will also force the hand of ML with their price structure. ML raised their price on the 800 and NM absolutely crushed that price point. The Legend doesn't have to be better, just equal to turn the fortunes in their favor. ML and their arrogant "obsolete" charge is foolish. Obsolete by definition means no longer produced or used. Many detectorist and their single frequency machines are still out there making great finds and having fun. Furthermore, single frequency detectors are still being made and sold. NM build quality is far and away superior to the Nox detectors.

      I thought I was pretty damn good, but this technology has me beat.
      Might be time to invest?

      Metal detectors often seem to have a 'Depth Gauge'.  How is it calculated? Is it the strength (or inverse of it) of the amplitude of the return signal?  So, for instance, everything else being equal, the 'deep' target would mean either a stronger target at greater depth or a weaker shallow target?

      While we're all abuzz with the announcement and advertised feature and performance characteristics of the XP Deus II, I'm wondering about tests that distinguish between detectors' target separation abilities.  'Word on the street' is that in trashy iron sites, the original Deus is still the best available.  Presumably those reports are based upon in-field testing, which of course is the real proof.  But the downside is, (AFAIK) these are qualitative observations, not quantitative.  Subjectivity involved?  Unfortunately, yes.
      We do have Monte's Nail Board Test for a special case -- iron nails near a single coin, all in the same plane and typically all on the surface of the ground.  Add depth combined with some mineralization (burying the MNB) and you've included another real world dimension.  But in the field, multiple nearby targets are seldom in the same plane.
      So you hopefully see the purpose of this post.  Has anyone seen/tried other methods to better simulate actual in-field conditions to differentiate between competing detectors to best be able to handle trashy sites?

      I mostly hunt in lakes and the bottoms are mostly all sand. A test on a sandy beach with the Equinox 800 and Xp Orx, both hit hard on a 14k 3.7 gram gold ring buried at 14". For mild ground I don't see a need for multi frequency. I do like the multiple frequencies on the Orx.
      Is there an advantage to multi frequency in mild ground?

      We have the Deus 2 just announced, Nokta/Makro Multi on the way, possibly the next generation Equinox from Minelab, and maybe even another Garrett multifrequency model to follow Apex, all coming in 2022. I guess we should even toss First Texas in there, as they just officially discontinued the CZ-3D, with the possibility something new will replace it soon. If this does not mean we are moving past single frequency, I don’t know what does. Or are we? There will no doubt always be a place for a finely tuned single frequency detector. However, if you consider Deus as selectable frequency, and Equinox as selectable/multi, then very many of us have already moved past a simple single frequency detector as our primary detectors.
      This is the thread to speculate on what is coming, where we are, and where we are headed. 2022 is shaping up as the year SMF (simultaneous multifrequency) finally takes off for real. In some detectors, it’s just companies chasing the latest marketing catchword. Multifrequency is only as good as the way it is implemented, otherwise we’d all have been swinging White’s DFX ages ago. It’s not enough to make a SMF detector, it also has to have genuine performance advantages. About the only given is that any multifrequency machine will outperform a single frequency on a saltwater beach. The rest, however, is very much up in the air.
      For some detailed explanation of the technology, and a history of past selectable and simultaneous multifrequency detectors, see my write up on Selectable Frequency And Multiple Frequency
      Where it all started, Fisher CZ-6 and Minelab Sovereign, both released in 1991. I think Fisher wins claim to being first, since Minelab takes a swipe at them in their Sovereign introduction. Notice how the misdirection on transmitted versus received and processed started on day one. 

      Fisher CZ-6 Quicksilver. The technology: Dual frequency Fourier Domain Signal Analysis. Patented state-of-the-art analog/digital electronics transmit two VLF signals (one 5 kHz, one at 15 kHz) deep into mineralized soil. The receiver circuitry had two ground compensated target signals to analyze, compare and identify. The result? Deeper targets, more accurate target identification. Wet sand is no problem for the CZ-6, it compensates for salt and ground mineralization simultaneously! Source Fisher CZ-6 Datasheet

      "The Sovereign" is the first of the latest generation of metal detectors from Minelab featuring Minelab's new technology called Broad Band Spectrum or BBS for short. This revolutionary new technology which is unique to Minelab has already been awarded patents in the USA, Canada and Australia and has several pending. Unlike other metal detectors which operate at just one frequency, or even the "newest" two frequency machines, "The Sovereign" actually transmits over a wide spectrum of frequencies. The resulting signal that is received from a target buried in the ground is processed by a microprocessor that removes interference caused by ground mineralization which limits the depth at which targets can be found, and often results in inaccurate target identification. The remaining signal can then be analysed to determine the actual composition of targets even if they are deeply buried, or if the ground is mineralized or salt water is present. Thus it is the only detector that can simultaneously reject both salt and mineralization while at the same time accurately discriminating the target, making it ideal for black sand beaches and many desert areas. In many areas that are highly mineralized and have been heavily searched in the past, "The Sovereign" will prove that many of the valuable targets are still there waiting for a Treasure Hunter with the proper detector to locate them.
