Fisher Impulse AQ (formerly Aqua Manta) Pulse Induction Metal Detector

Recommended Posts

The batteries are under the arm cup - rechargeable LiOn - The Russian site said 10 hours with an option for another pack (external?) for 20 hours.

I had my hands on a prototype a while back for a couple of days. It worked fine in our AZ dirt. Hot rocks were detected but depth did not suffer in what is sort of 2-3 bar (on an F75) dirt.  I didn’t play with the controls to try and balance out the hot rocks. It was quieter and significantly deeper than either of the TDI’s I have owned.  Black sand at a San Diego beach caused no depth loss - solid return on a nickel at 17” in the gravel of a wash in Gold Canyon was the same at this beach - solid signal at 17”.  My Nox gave up the nickel at 7 - 8” in the same sand with a very low VDI number  - the Nox got 12” with the nickel on the surface with correct VDI reading.

Here’s a better pic of the control box and the coil - my pictures.

Thanks for posting Rick.

I am pretty much boycotting heavy detectors. In my opinion with proper engineering there is no reason today why a waterproof VLF should weigh over 3 lbs and my desired target for a waterproof PI in under 4 lbs. If the Manta were to come in at the higher range of 1.8 kg then we are looking at 3.97 lbs. El Paso, we have a winner!

Looks like the Americans are fighting back, this can only mean good things for everybody.  Some healthy competition is always welcome.  I've always pinned my hopes on Fisher.

I will be watching with a keen eye at their new gold detector.

Sometimes a good thing comes along from “outside”.  Smart companies see the possibility and acquire the foreign development.  That’s exactly what happened here. Alexandre Tartar, the prime developer, posted on Carl Moreland’s Geotech forum and they got in touch. The project was promising enough for Tom Walsh the CEO to open his purse and do an “aquihire” of the “EuroTeam” who developed the Manta.

They have huge ambitions and hopefully this will be the first of a series of ground-breaking (literally - lol) developments.

The Americans are fighting back with a French designed detector 🙄

At Yorktown we fought back with a French army - our oldest ally. There is a memorial at yOrktown to the 600 French soldiers and sailors who lost their lives in the cause of American freedom at Yorktown and the naval battle of the Virginia Capes which made the siege of Yorktown a success.

Yes without the aid of the French, we'd still be a British colony. 

I have nothing against the French, I've been to France many times, it's one of my favorite places to holiday (and arguably the best food on the planet)....my point is let's give credit where credit is due.  Fisher didn't design the electronics, they may have designed the physical package, may have tidied up the electronics a bit, but they bought the electronic design.   Nothing wrong with that, we live in a global economy, our history, past and present is chalked full of foreign technology being realized in the U.S., acquisitions are common place. 

I'm sure it'll be a fine detector, but I'm a bit disappointed that with all the engineering horsepower at FTP, of all the American companies they couldn't design something on their own.

It wasn’t on their radar.  A PI detector is not something they had their sights on - then this opportunity presented itself and they went for it.  Pretty bold move for what is, after all, like all the detector builders, a small business. They bought more than the design, they hired the team.

Their own development goals proceed - I have no info on what that amounts to, my only insights were about the PI.

They make about 200 different VLF models under various brand names, I think it was about time they put their efforts into a PI or something new rather than another rehash.  I couldn't care less what nationality the people are who designed the detector, or what country makes it as long as it's good and the price is reasonable.  They should learn from the Equinox, make a great detector at a reasonable price and you'll sell a bucket load of them.  Overprice a detector and it will sell, but not near as well.  I can guess which method would make more profit.

      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."
      Another thread with Fisher Manta details
      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!

      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 .

      The Fisher Impulse AQ is clearly aimed at beach hunters. Specifically saltwater beach detectorists. It is a PI and as such is being billed as able to handle thick black sands. Pictures have been posted showing just that - saltwater beaches with heavy magnetic black sand content.
      Yet at the same time we are being warned this detector has a ground balance with limited range, and that it can't handle extreme ground and hot rocks i.e. gold prospecting.
      So what's the deal? Can it handle intense mineralization or not? I also wonder about the discrimination. The machine is clearly based on the Eric Poster/TDI in some regards but is also being billed as multi-channel, which TDI is not.
      I suspect just as with TDI that the discrimination is tied directly to the ground balance, and that in order to be effective as far as discrimination the ground balance is very limited. It has been mentioned that the all metal mode might be better for prospectors, which makes sense given what I am speculating. The discrimination is said to be "gold only" with high coin signals eliminated. That makes sense again as coin and nail signals are in the same GB range with the TDI. If they are going dual channel it may be employing two ground balance points as the limits on the discrimination range, something I suggested ages ago. It should be obvious that the TDI can use ground balance to establish one range limit - a second channel defining another limit seemed a no brainer to me. I always wanted to get an SD2100 to experiment with the concept since it allows the two ground balance channels to be set manually. Never got around to it though.
      Any PI can deal with relatively homogenous ground. Even the non-ground balancing White's Surf PI handles black sand beaches well, as long as the coil is kept at an even height over the bottom. I therefore think the machine will do well on relatively homogenous beaches. Given that it is said to not handle hot rocks well, how does that translate into Hawaii as a location? My main issue there with the Surf PI was basalt hot rocks embedded in blond non-magnetic sands derived from reef erosion. I have to question whether the Impulse AQ can handle those hot rocks given what has been said about it.
      What about freshwater? The is no difference between a freshwater Tahoe beach and some of the worst prospecting ground. Thick black sands plus hot rocks. Is the ground balance range tied more to saltwater operation? I would like to run this machine at Tahoe, but given what is being said I am questioning whether it can handle the hot rocks there.
      Not a bit of this speculation is a knock on the Impulse AQ. It is a machine targeting a subset of a niche market. In other words, a machine with very limited application and they are telling us that up front. I am not one to ever complain when I get a detector and it does not work when I try to make it do things it was not made to do. And there is always a catch, always limitations, always unexpected things that pop up in widespread use that can't be captured in limited prototype testing. I get all that.
      The bottom line is I am just airing the thoughts that are bouncing around in my head. I don't worry about it because I am perfectly capable of getting all the answers to these questions on my own. It's actually these types of questions that makes me want to get detectors because I love pushing detectors outside the envelope and finding the limits.... and then doing things with them others might not think of. It's kind of my detector super power. 
      They sure seem close to having a finished product. I hope so as once end of October hits I will have to wait until spring. Well, I don't have to, I just will. I may wait for the prospecting version anyway. We will see.
