      This detector is all but certain to appear, and probably before the end of 2019. I have been on a quest to get a high power ground balancing pulse induction metal detector that is reasonably light in weight and in a somewhat standard metal detector housing, preferably waterproof. Whatever detectors I personally use must have dealers and service support in the U.S.
      Edit 3/2019: The Manta has been officially named the Fisher Impulse AQ, a development that happened later in this very thread. It has also been revealed a gold prospecting model is under development. You can follow along here to get the latest information later in this thread and see the history. Or quick jump to the Fisher Impulse AQ Specifications & Data & Fisher Impulse AU Specifications & Data pages.

      The challenge I have for Fisher or anyone else is to make a dry land ground balancing PI that weighs under 4 lbs yet is more powerful than a TDI SL. The alternative is waterproof but under 5 lbs. The price must be under US$2000.00 Waterproof Pulse Induction Metal Detectors Compared
      The Fisher Aqua Manta (edit 3/2019 now known as Impulse AQ) has been rumored for some time, and confirmed by First Texas as a project nearing completion. Prior threads:
      January 2015 New Fisher Pulse Induction
      January 2018 New First Texas PI Under Development
      June 2018 Aqua Manta Pulse Induction Beach Detector
      The long story short is this is a project by Alexandre Tartar. The Manta is most likely an offshoot and improvement on the orginal Eric Foster Goldscan circuit. Alexandre has built at least three major prototype devices before the rights were acquired by First Texas. The following photos and information is derived from this thread where the V3 prototype is sold.
      Here are the basic specs as described in advertisement (the seller is French and translating):
      "I sell a "prototype" Manta v3
      There are only three copies of this detector and it is the best of three ....
      (See mantametaldetectors website)
      Pulse induction, works exclusively with mono coils to the beach, possibly for the land, but no ground control
      Calibrated for low conductors, gold and platinum, among other. Delay 7us of 17 volts more sensitive, deeper and faster than Deepstar
      Equipped with a coil, Manta, latest generation
      she has one month, the quietest and most efficient on the market, all brands included. (it will operate on TDI and Deepstar)
      Connector Type TDI, it accepts all coils (mono) of TDI / GPX
      Weight: 1.5 kg without battery that is worn at the belt
      headphone jack and on / off switch on the battery pack (lipo) supplied charger
      more than six hours of detection at full power.
      Carbon Rod Anderson + extra cane down
      braided nylon belt military style
      All the possible settings and need a good PI
      SAT speed, TX frequency, noise threshold, delay, volume, sensitivity....
      The delay was 7us , lets see gold ends
      very thin rings, earrings, jewelry hollow that other detectors can not see
      and of course, the wholesale jewelry it goes deeper
      Ferrous recognition by a double beep well marked"
      What I find interesting is this note "Pulse induction, works exclusively with mono coils to the beach, possibly for the land, but no ground control"
      Yet here is the picture that accompanies the advertisement. Now remember this is from March 2016, almost three years ago. The prototype clearly has labels for ground controls...

      Alexandre Tartar Manta V3.0 prototype
      The control markings as seen above:
      Volume Threshold Sensitivity Sat Speed. Motion. (recovery speed) Tx Frequency (transmit frequency, usually to offset for EMI mitigation) Pulse Delay. GB Type (the shorter the pulse delay, the more sensitive to tiny metal and salt water) Ground Balance (usually a ground balance control, but ad says this is lacking?) Statements by First Texas suggest version 1 of the new machine is aimed at beach use and may not be suitable for land use (gold prospecting). That in turn makes me think work on the ground balance system is lagging and may be key to the future of the machine. Will it be beach only, or have a future for gold prospecting?
      I have to assume the unit will be competitive when it comes to the horsepower, or why bother? Until now the Eric Foster Deepstar is generally acknowledged as one of the deepest beach PI detector’s ever made. And the ad says “more sensitive, deeper and faster than Deepstar”. That being the case what really has my interest is the weight and compactness being displayed. The following photo collage from the advertisement shows the size of the control box and belt mounted battery:

      Alexandre Tartar Manta V3.0 prototype
      Granted the battery is belt mounted, but that is one tiny control box. I have to think that First Texas can slim down the circuit board and use a top notch integrated rechargeable battery and get this machine into a very compact package - hopefully waterproof and with wireless headphone capability built in.
      Well, that's about all I know about this one. This thread will collect any new information as it is available. This is one of a couple detectors I am watching so fingers crossed for a 2019 release. It is encouraging that Alexandre's original website at http://www.mantametaldetectors.com/ has been taken over by First Texas and is displaying this banner:
      Fisher Research Labs - New Pulse Induction metal detector COMING SOON!

      Anyone out there know any information on this machine ? It supposed to be being tested and could be really interesting when released .
      2019 Update: The Manta is now called the Fisher Impulse AQ - see Fisher Impulse AQ Detector Data & User Reviews
      May be able to discriminate Iron out .
      You Tube this .  AQUAMANTA A1 TESTS HARDELOT . All in capitals . 
      It is compared to the Sovereign and CTX , the Aqua is the last one tested . Unfortunately LIKE the Equinox most of the time before release , its in a foreign language .

      My VLF detectors are rapidly sorting themselves out and I am satisfied I am doing about as good in that regard as can be done. There really is only one area of metal detecting left that is bugging me.
      2019 Update: The Manta is now called the Fisher Impulse AQ - see Fisher Impulse AQ Detector Data & User Reviews
      The Garrett Infinium was the first waterproof ground balancing PI and not a bad first effort. White's TDI might have improved on it but White's never did a waterproof TDI. Surprisingly, Minelab has never done what I would consider to be a true waterproof saltwater beach hunting PI. The SDC 2300 really is a prospecting detector first and second. I finally ended up with the Garrett ATX, which currently sets the bar for a waterproof ground balancing beach and water detector.
      Yet the ATX housing was designed more for military use than beach detecting. The coils are overly expensive due to an integrated rod design. Worse, the detector weighs in at 6.9 lbs and cannot be hip or chest mounted.
      In a sign of faith I am going to sell my ATX and wait on whatever First Texas has in the works. As Rick Kempf posted here previously, First Texas hired Alexandre Tartar and purchased the rights to produce a version of his Manta PI Project. And to quote First Texas engineer Carl Moreland from this thread "Yes, we've hired Alexandre. Yes, we are working on PI. I was personally working on PI before hiring Alexandre, but now we are seriously working on PI."
      Fisher has not made a PI since the Fisher Impulse was discontinued back around 2013. This collaboration with Alexandre Tartar gives me hope that First Texas can get something out in the next year or two. My bar is low - a waterproof ground balancing PI at least as good as the ATX in a more ergonomic package. Seems fairly doable. Another company that may come out of nowhere all the sudden is Nokta/Makro as we know they are working on a PI. I don't know, but I think this is First Texas' game to lose at this point. So there you go, ATX going up for sale and a spot held open for whatever company can meet the challenge. Good luck First Texas - I am rooting for you!

      No, I actually do not know what the new Fisher Impulse Terra will be called. It is just that I doubt it will be called the Impulse Terra and Impulse AU seemed like a good pairing with Impulse AQ. Probably wrong but I can change it when we find out for sure. The main thing is this dry land gold prospecting version of the Impulse AQ is 99% certain at this point, so I wanted to start tracking it as a separate model with what is know about it so far. Which is not much. WE know testing is taking place with an 8" coil but do not know for sure if that will be the stock coil or not. It would be a good choice for small gold but not good for covering ground or for larger deeper gold. OK though if that's what they go with. Presumably a 12" coil is a possibility as stock or as an option.
      It will have to ground balance, and it may or may not have ferrous rejection capability. I personally hope it does, as some areas are full of ferrous trash and missing some gold is worth it to be able to use a PI in those areas.
      Anyway, will be updating as I find out stuff. I'm kind of more interested in the beach model myself as i have nugget detectors already, but it will depend just what the feature mix is that will swing me one way or the other.
