Recommended Posts

So I was verified today by someone I cant name for obvious reasons that minelab will be anoucing a new pi in May at the ballerat dealers conference whay that pi is is a unknown it could be a new sdc a new gpx or new gpz that we have to wait and see but I'm excited either way and hoping I won't have to sell my house for it

Given what was said to dealers at the conference last year regarding this new PI, they expect an even more insane price tag to be accepted because the performance of the prototypes has been outstanding. Expect a 'rush' akin to the release of the SD2000 they reckon. Maybe they'll see sense and rely on volume of sales and not even higher profit margins???....not holding my breath. MT, the only 'true' verification will be in May. Until then, we'll hear more of the same well-sourced rumors and nothing more....

And since the GPZ is not a PI it would not be a new ZVT replacement....

The GPZ IS an evolution of a  Pulse Induction detector, just with extra bells and whistles. Just coz Minelab prefer to use another acronym, (ZVT) don't mean it aint a PI.

Did you ask Minelab if ZVT is just another "acronym" for an evolution of PI technology? 

https://www.minelab.com/__files/f/254716/KBA 24-1 Basics of the GPZ 7000 Technology Zero Voltage Transmission (ZVT).pdf

"It should be noted that the PI receive period is half that of the ZVT period, because the PI system shown in figure 2 transmits for half the time and receives for the other half of the time, unlike ZVT that transmits and receives simultaneously just about all of the time."

From the same doc referenced by Dave above

"Another disadvantage of PI is its capability at detecting very large nuggets compared to CW metal detectors, such as ZVT. CW means Continuous Wave and includes all technologies that do not have zero transmit periods (almost all technologies other than PI). Zero Voltage Transmission (ZVT) – ZVT has the same major advantage as PI for ground balancing in not detecting the major soil component X, but has the same advantage of CW metal detector technologies compared to PI for detecting very large nuggets because ZVT is CW (unlike PI that is not CW ), and also the same advantage as PI for being relatively insensitive to saline soils compared to VLF.

Perhaps Its just Minelab attempting to recreate the wheel.... you'll notice that 'time constants' are mentioned as well as the sampling (measuring) period which are all PI references. The only constant wave part is during the receive- sampling section of the code....which shows its more of a hybrid system with perhaps PI as its core....remember it still has the same audio as the GPX's and the dual channel MPS (which isnt acknowledged but easily heard by any operator) reverse tone audio responses. Maybe someone can correct me, but I seem to recall the very few references of the operating frequency being in the PI ballpark also..... Minelab technicians also referred to GPZ as a PI type when it was released initially. I 'feel' that going by user experience and the tech-speak, the 7000 is a hybrid PI with a fancy name. But of course the tech works......and works damn well. Hopefully ML expand on the tech and bring us all something even more amazing

I'm going to make my prediction now. GPX 6000, mostly the same as the 5000, other than the chip system to prevent off brand coils 😀

      It has been common knowledge among those paying attention that Nokta/Makro has been working on a new simultaneous multifrequency detector for some time now. The Simplex+ has been specifically stated as being the potential housing for the new unit when it appears. This post from 2/17/2020 reconfirms work on the new model:
      "Hello all... yes, the name has been chosen and the machine is in the works. Cannot confirm the release date as of today but hopefully I will be able to share more info further into the year. Hope this helps...."
      People often bring up patents as a reason why new multifrequency units have been so rare to appear, but the fact is patents on machines like the 5 & 15 kHz Fisher CZ, White's 3 & 15 kHz DFX, and Minelab BBS (billed as 17 transmitted but more likely 2 - 3 processed frequencies out of 17 transmitted) have all expired. Nokta/Makro has plenty to work with.
      Given the speed with which Nokta/Makro has brought new machines to market in the past and the fact they have a mostly proven housing in hand now via the Simplex, I expect an announcement by this fall with a detector available either before Christmas or next spring. If I was them right now I would be collecting warranty claim info to make sure the Simplex housing is bullet proof before launching the new unit, and that should be going well by now. In the meantime work can proceed on design and testing of the circuit.
      Frankly, there is no need to do anything radical to be successful. If Nokta/Makro simply did what Fisher should have done years ago and mage a digital clone of the CZ but with target id instead of meter, put in a waterproof Simplex box with wireless, and at their normal great pricing, they will have a winner. Many people would kill for a Excalibur BBS clone in a Simplex style housing. The main thing multifrequency offers is good VLF saltwater performance, and a Nokta/Makro Multiplex (my guess ) model would be an easy sale for a lot of beach hunters plus the general coin, relic, jewelry market.
      There will probably not be any real news for some time but when I hear anything, this is the thread I will post on.

      Nokta/Makro Multifrequency metal detector?

      With 2019 in the rear view mirror what will 2020 bring? Multi Frequency? Pulse Induction? One thing is for sure, this company is going places fast!

      From the Prescott Daily Courier http://www.prescottaz.com/m/Articles.aspx?ArticleID=140625 
      Jack Delano Gifford, 75, passed away Jan. 3, 2015. He was born in Miami, Arizona, the son of Norval and Mayme Gifford. When Jack was about 6 years old, he and his family moved to the Phoenix area, and he lived there until he moved to Prescott, Arizona.
      After high school, Jack served his country in the National Guard for six years. During that time, he also earned a technical degree in electronics and started a family. In his early electronics career, he worked in the aerospace industry. During a slowdown in the '70s, he was recruited by a metal detector company and worked in that industry until his retirement. Jack was an entrepreneur and an electronics design engineer, and founded three companies. The last one, Tesoro Electronics, brought him many friends and national and international acclaim for his designs and his support of the industry. He started that company in Glendale, Arizona, in 1980 and when he moved it to Prescott in 1991, it provided new technical jobs and industry for this area.
      Jack started visiting Prescott when he was in high school and, during his careers, he and Myrna would visit the area for some much needed R & R. Eventually he realized he could move the company to Prescott so they could enjoy the Prescott lifestyle full-time.
      Jack loved his family, motorcycles, metal-detecting and working on vintage stereo equipment. He also built the speakers to complete the systems, many of which he gave to family and friends. After retirement, he became a PADI-certified scuba-diver. Jack joined American Lutheran Church and served on their board. He was part of the Tuesday night men's Bible study and worked in ALC's outreach programs such as The Rock and Teen Closet. He also worked at the Prescott Community Cupboard Food Bank and served on their board.
      Jack is survived by his wife of 54 years, Myrna; sons James and Vince (Katy); three amazing granddaughters, Isabella, Lily and Charlotte; sister Gloria Gray; and many nephews and nieces. He was predeceased by his parents, infant daughter Kelly Jeanine, and sister Glenna.

      From the Codan news release at http://www.codan.com.au/Portals/0/investorpubs/22 AXS Announcement - Minelab awarded $6.7m contract.pdf (copy below):
      "Cooperating with NIITEK Inc., the HDD will combine Minelab’s new Multiple Frequency Continuous Wave metal detection technology and NIITEK’s advanced ground penetrating radar."
       
      31 August 2016
      MINELAB AWARDED CONTRACT TO DEVELOP NEW HANDHELD DEVICE DETECTOR FOR THE AUSTRALIAN DEFENCE FORCE
      Minelab Electronics, a wholly owned subsidiary of Codan Limited, has been awarded a $6.7m contract by the Department of Defence to develop a new Handheld Device Detector (HDD). The funding received under this contract is to further develop a dual sensor metal detector which incorporates ground penetrating radar. It will partially offset the development costs of the product, and the project is expected to be completed by 2018.
      The development of the HDD builds on Minelab's success in technology development and product innovation for use in military programmes.
      Codan is particularly pleased to be of service to the ADF and to provide an enhanced capability that currently does not exist. Once the HDD enters into service with the ADF, we are confident that other militaries will seek the same level of capability, broadening our market for countermine products.
      The contract supports Codan's stated strategy of growing its profitability by improving and broadening our product offerings while ensuring our value propositions remain relevant and leading-edge.
      Previous to this award, in March 2014, Minelab was selected by the Department of Defence's Rapid Prototype Development and Evaluation (RPDE) programme to receive
      $1.0m in funding to further integrate metal detection and ground penetration radar technologies into a lightweight and compact mechanical platform. In December 2014, RPDE provided an additional $1.3m in funding, and Minelab subsequently produced an advanced prototype of the HDD.
      Cooperating with NIITEK Inc., the HDD will combine Minelab's new Multiple Frequency Continuous Wave metal detection technology and NIITEK's advanced ground penetrating radar. The HDD was designed taking into account the comprehensive requirements of the ADF, supplemented with feedback from Army User Groups. It will include advanced detection technologies as well as new standards of compactness and ergonomics.

      I was gone part of the morning but when I got home it was a pleasant surprise at my door.
       My I believe new Simplex was waiting for me. It came on a two day priority mail that I believe that Dilek had something to do with. It came back double boxed like I sent it .
       Life is great when you’re dealing with great people and a great company. You know up front who you want to spend your money with.
       Dilek I sent you a personal message but let me say it again. Thank you so much !
