Impulse AQ Limited *** Hair Pin *** All Metal Mode


Recommended Posts

Here is a very short video, I don't have much time right now.
But I would make you more videos with all the targets in the wet sand and on the wet sand for see the differences.

I start with the hair pin in ALL METAL.

All ferrous targets are recognizable in ALL METAL mode

Yup, the same audio tricks that work for all other PI detectors work for the Impulse, and with the same limitations. If I had the inclination to do videos I would put one together showing the good items that can be passed by ignoring double blips, but for properly oriented rings versus hair pins, it does work quite well. When I finally get out again with the AQ I will be ignoring such signals to focus on clean deeper signals. I’m also aware I might be passing on some gold chains, ear rings, pendants, and certain rings on edge, all of which if properly shaped and oriented can cause a double blip signal. But the odds are very much in favor of the hair pin, and as long as rings are truly the main goal, they can be treated as a trash signal. But that is not a 100% thing but instead a calculated risk.

Long story short if you ignore the tones and mute modes the AQ is a very powerful PI detectors, and all the same audio tricks and tells we have used for decades on other PI detectors also apply to the AQ.

Yes and no, because the faster a PI (Pulse Per Second) the more audio information there is if the detector does not integrate the signal too much.

With the Foster SSV3 at 10,000 PPS it was easier to recognize the pulltab than with any other PI.

You have to be above 4000 PPS to start to recognize the double loop of the Pulltab, and you need a very reactive detector with a weaker integration.

It's funny because we see it with the video editing software, we see the sound signals different from each other.

With a fast PI (weaker integration) /  > 4000 PPS in ALL METAL / AUDIO RESPONSE :

All this is valid inside the sand and not in the air, nor placed on the sand.

Recognition is optimal when the target is at the limit of depth.

To get there, you just have to lift the serchcoil up to the audio signal loss limit for identify.

When you get used to it during research it goes very quickly.

You are singing to the choir Alexandre and misunderstand if you think I am not aware of and appreciate these things. I’m in full agreement that the AQ is wonderfully descriptive in its all metal response. I am always however keeping in mind two audiences. Those who know PI detectors, and those who do not. Using all metal modes and reading targets for size and shape is not totally unknown even to people who operate VLF detectors in all metal mode. It’s an old PI trick and the AQ may be better at it than most, possibly even the best. But discriminating items by size and shape is not the same thing as standard VLF discrimination. Orientation is key, and for demonstration purposes ideal orientations are always chosen. The method in full time use requires skill and judgement, and at best is always a bit of a gamble. There are valuable items that will deliver similar responses and those items will be missed when relying on these sorts of audio tricks as a discrimination methodology. That is just a fact, an important one, that I refuse to leave out.

You and I are 100% on the same page as regards AQ. The difference is you are presenting the best light only... I will be also be mentioning the caveats. I am a firm believer that the best way to introduce a new detector is with realistic cautions included, because not everyone reading these forums is a knowledgeable and experienced detectorist. They deserve to know both sides of the story, not the best case only, everything is just right narrative.

The reality is many people will never be able to develop these kinds of target reading skills. Perhaps they have poor hearing, or simply no patience. They need or want detectors with a clear tone difference or that ignore trash entirely. PI detecting is a specific skill set, and huge numbers of VLF detectorists try PI detectors and go back to VLF for these very reasons.

Yes but beware, the IMPULSE AQ is not made for the amateur, it is designed for an experienced prospector, and people who want to find more gold with a more advanced and more complex search mode.

It has never been said otherwise, if you want ease and display of conductivity you will need an equinox or a BBS or a DEUS or others.

But with 60% less sensitivity in the best of cases, on wet sand.
L'impulse AQ is not a coinshooter.

The philosophy is this:

Either you wait after the gold which is inaccessible because too deep comes back to the surface thanks to the sea, at the risk that someone detect before you with a more powerful detector.

Either you decide to spend more time learning, digging etc ... But you find before the others and after the others ...

Absolutely understood and agree Alexandre! You made this detector for me, and I thank you very much. However, the dealers and marketers that are the ones that will actually be selling the final version of this detector in the long run will not be so up front as you about all this. They want to sell detectors, and will take money from anyone that has it.

There will be those that will say most anything to sell a detector, and some will sum the AQ up by saying it will go deeper then anything else while offering new, state of the art discrimination. Which is not entirely untrue, but is misleading. So while it is true the AQ is made for knowledgeable, serious detectorists, it is inevitably going to be sold to and fall into the hands of those who do not understand it.

My goal is to make sure people do know this is a serious, powerful metal detector that can do great things for those who understand how it works and apply themselves to using it properly. Anyone coming from a PI background I think will be extremely pleased with the AQ. It is the VLF people moving to PI for the first time I am in guard for. Trust me, things have already been said on forums the last couple years that have set the AQ up for unrealistic expectations. See example here.

This forum will the place where people get the full story if they wish, and statements like the one you just made are very important in making sure the AQ gets into the hands of people who will understand it and appreciate it. So again, I thank you! 👍🏼

Steve, you completely misunderstood my posts. You jumped to the conclusion that I was clueless about Pulse Induction and the Impulse. 

I've been casually following the development of the Impulse AQ for many years. It's getting so that in order to post here, a person has to give a long explanation of what they know in order to be understood. Try not reading between the lines so much. I know very well that the Tone ID on the Impulse is very crude compared to a VLF. I also have owned two PI machines and understand the tone quality involved when discerning targets.

I was just trying to understand what these Tone and Mute settings do and how they perform. Maybe I didn't communicate it very well.

      We have been told on several occasions that it was impossible to export the Aqua limited outside of the United States and now on the official page of Fisher I find this publication.  How is this possible?

      Was in Myrtle Beach for most of a week. Got the AQ well into the chop on this trip. I stayed in cuts between sand bars and the beach so the waves were not terrible and I was able to stay on my feet. Ran all metal all the time. It ran mostly quiet with ATS on 7, Sensitivity on 4, delay on 10. If I ran delay less than 10, each step lower got a good bit more noisy. ATS lower than 7 did not make for good hunting either. Still left lots of adjustment should I venture beyond the sand bar. Had the big coil on, did not take the 8 inch on this trip. The waves did make for an effort controlling the coil, but made it through without mishap. Did not go out detecting on Thursday when Elsa went through. Elsa seemed to mostly push some sand up on the beach in the area we were staying; that made the bottoms of the cuts softer than they were early in the week. That said, On Friday in a soft bottomed cut, had a fairly faint but repeatable signal that after four scoops became very loud and I got it on the fifth scoop. Nice little 2.3 gram 14K gold pendant.

      Sorry, I can't seem to find my previous thread on this subject. To recap, my AQ wouldn't power up, so, it was sent in to Fisher for repair. They claimed that it was the battery. I had my doubts, as I had tried a second battery with the same results. Anyway, they claimed it was only the battery and sent it back to me with a new one. On a side note, I had just sent the electronics back to them, and kept all the rods, cuff, and charger to save on shipping costs. Well, it seems they want EVERYTHING sent back when they do a repair. That's a first for me. They even told me that you shouldn't remove the arm cuff at all! It's something that they have to do, and not something the customer is capable of as it might damage the cable inside the rod.  Good grief, what a design. Anyway, when I got it back, I noticed that the cable from the battery to the pod had been changed. Hmmm, I wonder if that was really the problem and not the battery. Otherwise, why change it? Oh, you think they might have sent a new and improved one? Think again. I didn't think they could make that design any worse, but, they managed. It's even longer that the original, and wimpier IMO. And what is the problem with using 90 degree connectors to reduce the risk of cable damage? Well, it works now, so, I guess I can't complain too much, in fact, the new battery is a lot better than the original. The last hunt, I got over 3 1/2 hours on it and still had a green light! That's definitely an improvement. Now, if I can just find something good that my other detectors couldn't find!

      Hi guys!
      I watched the treasuretalk on youtube for couple of days ago and Myer's metal detecting confirmed he is going to bring in AQ final edition in the shop next month in july! just wanted to ask others if it is true and anybody heared anything about it,Thanks!

      Walked down to the local watering hole; brackish water bay tributary, pretty well cleared out over the years but a bit trashy with bits of iron. Ran delay 7, sensitivity 7, threshold 4, volume 8, ATS 6.5, reject 6; mostly all metal but some tones and mute to check targets.
      Initial reaction is that it is a little easier to hear the edge modulation with the 8 inch than with the big coil. I walked away from several targets that were very pronounced double tones then had a more subtle edge that I told myself to walk away … but dig to verify. That was the little fish hook. The odd shaped washer, to the right of the fish hook, fooled me; it sounded pretty good in all metal and in tones. The rest of it is all non-ferrous. Some of the small targets fell through the scoop several times before I finally capture them and got them in the pouch. This set up finds fairly small targets well. Tones seem to be more pronounced to me with this coil than with the big coil with some similar settings, yet I think I still hear iron better in all metal than in tones ... maybe some setting tweeks would change that around but I'm pretty happy in all metal.
      I did have an interference issue. A boat about 100 feet from me fired up and the AQ talked and talked. Stepped through the frequencies and no help there. I was shallow enough the detector head was above water so I went deep where the detector electronics were well under water and, surprise to me, that did not help either. Dropping the sensitivity down to 2 made it usable. Once he lowered the boat lift, backed off and motored away I could turn the sensitivity back up and hunt with a very quiet AQ.
      Did have a great blue heron land on the beach and walk into the water. Got about 30 feet away from me so I stayed still and watched it turn its head looking for minnows, catch and eat them. After a few minutes it walked around the beach corner towards the boat lift then flew about 2 hundred yards down the water.
      A good afternoon in the water.

      Didn't get out this past week since I was under the weather.
      Started out with the detector being really unstable. Water got into the coil connector. Blew the water out of the connector and tightened the back-shell and everything was good to go. I also have noticed when I'm in shallow water she's a little noisy and a lot of falsing (water way below the connector). She's pretty stable when completely covered. I do run my machine hot in all metal.
      One old beach I hunt always has sand piled in to the one side. No sand movement in this area other than more accumulation. For years I said there has to be targets just out of detection range. Well not for the AQ. I did find a few targets in this area. I had to work slow since these targets were pretty close to the depth limit and I was running hot. A few pieces of crusty Silver and a nice 10K ring dated 1946.
