Can New PI Advances = More Au?

Recommended Posts

I remember when I purchased my 1st metal detector, a GP 3500. My family and friends thought I was insane to pay over $3000 for a metal detector LOL. It was instant love for me when I held her in my arms. Yet just like when the shine is wearing off your most recent girl friend and some habit of hers is starting to bore a hole in your brain..........it did not take long for me to tire of packing that lead acid battery around. What did that thing weigh? 9 lbs? Before you could say Pocket Rocket, I had one hanging off the side of my Baby.
Now it is almost 2015 and battery tech has advanced by leaps and bounds. I know next to nothing about how the engineers have done this but I know the batteries in my XP Deus must be something special to weigh so little but pack so much punch.
Will it be battery technology that will finally allow a new PI to offer  performance close to what Minelab PI's are famous for yet weigh under 4 pounds? Is this a realistic goal to ask of metal detector manufacturers? 
We may soon see some interesting PI machines marketed. Fisher is working on one as is Nokta/Makro promising PI and hybrid machines. Nokta/Makro is shaking up the VLF world through their customer service and quality manufacturing and would it not be wonderful if they provide some real competition to Minelab?
Personally, I believe if a manufacturer can develop a lightweight PI with improved discrimination it does not have to obtain the impressive depths Minelabs are capable of. If I can ignore most iron and dig more non-ferrous targets even though I occasionally miss deeper nuggets I am going to have more gold in my poke at the end of the day on a consistent basis. Some desert gold hunters might disagree and maybe rightfully so but if you hunt in areas where logging has occurred I surmise you may concur. Just as the Minelab 2300 has taken the prospecting community by storm by finding more small and/or spongy gold while giving up some capability on big, deep nuggets, a PI with improved discrimination is going to allow you to dig more gold and less nails, wire, and degraded cans. You would effectively view more dirt in a day by not spending so many of your precious prospecting hours digging ferrous targets. JMHO

Good post Merton - I agree.

"Will it be battery technology that will finally allow a new PI to offer performance close to what Minelab PI's are famous for yet weigh under 4 pounds? Is this a realistic goal to ask of metal detector manufacturers?"

Beyond realistic. I actually think the Garrett ATX is reasonably close to a Minelab PI in performance and that Garrett could have snuck it in under 4 lbs if they had even halfway tried. It even has decent surface ferrous discrimination. The SDC could easily get under 4 lbs in a different configuration, and no special batteries needed in either case. The TDI Sl weighs in at 3.5 lbs but it is an old circuit design and lacks the horsepower, as did the Infinium.

If Minelab, White's, or Garrett do not do it Fisher or Nokta/Makro will. Or somebody else out of left field. But one way or another we are going to get a fully self contained reasonably powerful ground balancing PI in a package under four pounds, and I am guessing it won't be much longer before it happens.

I actually think Minelab is a sitting duck in the $1000 - $2000 price range for a PI which is why I am amazed the competition keeps missing the mark. ATX, 3.9 lbs at $1999 would have rocked the boat. 6.9 lbs for $2120 not so much. Note to manufacturers - you are not supposed to be charging by the pound!

I asked White's years ago - "can't you just stick MXT and TDI circuits in a box, and with proper coil be able to just switch between them?" "Oh sure, no sweat" is the answer! Then WTF have we not seen it yet?!

Steve, my guess the answer to your question is profit margins. Bummer.

Probably the same reason as to why I cant have one cell phone from Verizon with two different numbers....One for my business and the other a personal number for family/friends.  They want me to buy two phones instead.

Price it the same as both units purchased separately. It would cost them less to make since the body of the detector is much of the cost. They would make more money than me buying each one separately. I would without hesitation buy such a machine, as would others. In fact, I might be willing to pay more than the combined cost of both machines purchased separately. Think of how useful it would be to be able to hunt with a PI and then on getting the target, switch to VLF mode. You would get an immediate id on most targets. Deeper ones you would have to start digging, but at some point that target id is going to kick in. The efficiency factor in time not lost digging every target would be worth it to me. I have carried both to do just that, and it works. But who wants to carry two detectors all the time and switch between them? It only works if the capability is in a single unit.

Dual sim card phones are easy to get in the rest of the world. But again, except of Verizon and South Korea, the rest of the world used GSM (using sim cards) not the wacky Qualcomm standard.

      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.
