Fisher Impulse AQ Discrimination Explanation


Recommended Posts

Things have been weird lately.  After a long time away from Metal Detecting I suddenly get real interested in collecting coins and have been buying some. So I think again about detecting as maybe I could find a few good ones this way.  Of course I gotta go to Prospecter/Detector to see what the latest greatest is.  Unfortunately I can't get on the website?  I'm thinking what happened? I try for a few days in a row to get on and I'm starting to wonder if somehow I had been banned or something from the website.  I did see something on Face book about Steve going to Alaska for a while but I never heard of him shutting the site down while he was away before.  I was so relieved when I got a message today about the site being down and now back up.  First thing I come across at the website is about the new Fisher Impulse AQ.  I start reading about it and watching a couple youtube videos and think this looks great!  I see there is a lot of discussion here about it over a year ago so I'm thinking this thing must be for sale by now.  I check and see none at Gerrys website and none for sale on ebay so I came back here and start reading up on this thread through all 14 pages where it kinda dies on May 14 2020. But then again that's about the time Covid started hitting hard so I suppose that could explain the delay?  

Lets say it is still evolving. I believe the Limited is available thru Fisher now but I would advise waiting for the final version.  

When? I have no clue.

I think most would agree that the AQ would not be the best choice for coin hunting.  You'd be much better off going with a Minelab Equinox.

Even if you were set on buying the AQ, it may be years before it is released if ever. They made 100 prototypes over a year ago which are still being offered. Apparently they have not yet decided whether to put a final version into full production or scrap the project. Hence the silence.

Joe, I appreciate the info.  I imagine this detector wouldn't be the most ideal coin detector.  I've been completely away from detecting for a while.  I didn't think I missed it that much but when I heard this detector in operation it took me back.  It has the sound of a GPX and I've owned a couple in the past. Strangely I miss that sound!  

This detector even if not perfect seems to have some redeeming qualities.  It doesn't cost 5 or 7000 dollars like some of the minelabs.  It doesn't even cost as much as a 3030.  Someone using one on youtube could see a nickel at 19" in beach sand.  I don't see a lot of other machines that could make that claim at twice the price point.  It does have some ability to discriminate but hasn't proven it's self and almost for sure doesn't discriminate as well as a top end coin machine.  But for the money not bad and seems to be a step beyond the Whites TDI.  But if Fisher won't fully field it then I would have to think there are other issues with it that haven't been revealed which could even be things beyond function like patents etc.  But of course only the top dogs at Fisher know for sure.

Actually there is no mystery about the AQ, with tons of information and reports on this website, including this thread on how the discrimination works, which is not really much different than a properly tuned TDI, but with more depth. The Limited version was due to an unfinished physical design more than anything else. But for depth you can get a used GPX that will do as well or better for coin and relic detecting. With all the limitations as far as digging trash as one should expect using a PI.

I always thought the discrimination aspects of this detector were oversold, which is why I wrote this thread, to bring people back to earth. Nothing in my use of the machine makes me think I was wrong in any way. The original power user of the prototypes used all metal and the typical PI audio tells for max performance, which should tell you all you need to know. The machine is not tuned for silver, but gold, and a GPX will outperform it on silver.

Fisher has the makings of a great beach PI in the AQ, if they can fix the bugs that caused failures, and complaints in places like Hawaii, and get the physical package right. Even then all we will have is a great beach PI, and I still question that the market there is anything but a niche market in a niche market. The AQ has you digging tons of trash, just like any PI, and so it will not put a dent in the VLF market. The gold prospecting version was always going to be the big winner for Fisher, if they can get it done, than the AQ was ever going to be. With all the things Fisher has needed to do, the emphasis on this niche PI beach detector has puzzled me, and it may be the folks at First Texas have come to that realization also.

Appreciate the reality check Steve.  I owned a TDI years ago.  I liked it but I felt the discrimination was pretty poor compared to a VLF detector.  Doing some basic testing with it, I initially thought it would discriminate pretty well but real world use proved me wrong.  

I happened to break out my Eureka gold today that I hadn't used in several years. No gold around here but I was looking for my property line stake.  This will sound like a crazy story because it is. This past Sunday morning at 3 AM someone knocked on my door. I woke without my glasses and had no idea what time it was and answered the door.  A 30ish man was at the door and asked if he could please come in, that he was shot and to call 911.  I did, and long story short got him help and the Sheriff and squad out to our place. He had two bullet wounds so I thought he was shot twice but apparently one wound was the entrance and the other the exit.  The sheriffs went next door and found another man wounded even more severely and life flighted him to Duke hospital in Durham NC.  Well, the property line stake I was looking for with the Eureka was along the property line where the shooting happened and I happened to see a spent 9mm casing on the ground while looking for the stake so I gave it to the Sheriff today and they ended up borrowing my Eureka for a few minutes to look for whatever. I probably should have offered to operate it as it's a bit touchy with that AA battery pack.  The man who shot the two men was staying next door with his mother and is a convicted Felon and I learned today from the Sheriff the mother is a convicted felon too! This used to be such a quiet place to live.

As to detectors, I'll probably sell the Eureka, skip the AQ and pick me up a Equinox 800 to look for coins and who knows, maybe spent shell casings too?  In the meantime I'm keeping my 10mm Glock close and will be more reluctant to answer the door at 3 AM.  However doing so might have saved at least one person's life so I have no regrets.  Sadly, there were several people next door where the shooting took place and no one called 911? Not even the shooters mother. I imagine they were too busy trying to hide evidence so it's very fortunate that one man escaped.

I don't see an Edit button so for accuracy's sake, I should mention the shooting happened Saturday morning, not Sunday.

The edit button is on the top right hand side of your post. Just click on the three little squares and the edit function along with other options appears.

 Schoolof hardNox, I've been to that school quite often.  I see the three little dots, thanks for the tip!

      Received my catalog from Kellyco today and they proudly announced that they are looking forward to offering the Fisher Impulse AQ in 2022.  The write up that Kellyco gave made it sound like there was substantial discrimination with minimal loss of detection depth with the AQ.  We shall see.

      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.
