Fisher Impulse AQ Discrimination Explanation

even if they are rotten alexander?

Between 7µs and 8µs cutting the 5c, 2c and 1c requires increasing the reject a little more, but from 8µs included the rejection is set at 50% and gives a multitone sound.

If you cut the 5c, 2c and 1c you will lose beyond 18K 25 grs depending on the diameters.
However the 14K is not rejected. And of course below this weight in 18k it is not rejected either.

Discrimination is an advantage in polluted areas even on a BBS, but it must be used with intelligence.

In addition you will detect gold and iron at the same time, and it continues to detect gold.

I have to admit the whole journey must have been so interesting!!!!!!!!

Thank you Alexander for answering the questions we are asking.  Many engineers from other brands should learn from you

ABOUT "REJECT SETTING"

The rip current phenomenon leaves areas hollowed out by the sea behind.

These areas are often more polluted because it concentrates targets of all types.

I had the opportunity to do statistical tests in TONE mode.
THE goal was to hear ferrous and non-ferrous.
And better if possible to see how many holes contained ferrous and non-ferrous simultaneously!

The IMPULSE Series is equipped of that I called ZTS® technology, the latter focuses on low conductors such as gold but also the high gold conductors.

The ZTS® system eliminates the need for recovery speed.

We do not detect next to iron but in the iron and under the iron !

At the beach in a polluted zone (rip currents zone) this technology allows to find up to 30% more targets mixed with a ferrous.

Finding done on 450 holes in TONE MODE in a beach rip currents polluted area.

The ZTS® system is effective in TONE or MUTE mode, unlike the other competitor the loss of sensitivity is minimal compared to ALL-METAL mode.

This advantage can be significant depending on the situation where no other detector can detect.

Yes it's true, I knew you were going to react!

I have to ask....... what does the 5c, 2c and 1c refer to in this sentence......im having an old guy moment?  "If you cut the 5c, 2c and 1c you will lose beyond 18K 25 grs depending on the diameters"  Now..... how many have found an 18K 25 gram gold ring?  I have a few near that 25 gram weight .... but very few and none 18K.   IF we start loosing 18K and above arent they the heavy gold since everything sinks to its equal weight?   

Steve are you saying with that salt setting .... we have 7uS..... but its going to make little difference over say what the Nox now gets on the small stuff because both are using a standard salt setting?   Will that be the same in the wet sand?   AND would the Nox come closer to finding a small gold chain?   Im talking in theory..... since the machine isnt out yet.

What i already like about this machine....... its a niche machine.  Yes i like that.   Everything is geared to GOLD on the beach.  Anything discussed or adjustments made will be relevant.   This is a real gamble for Fisher...... but for us its can be a win.... especially if they or other companies continue this progression.    Getting away from a multi use machine to one designed for a specific purpose has always been a better choice for the advanced hunter.

Please read the posts Dew...I linked directly to the discussion of the 1c, 2c, and 5c Euro. First link in my last post and the discussion prior to it at that link. There is even a picture of the coins. To be honest, you have so many questions because you don’t follow the entire discussion and ask questions answered before. It’s like the small gold salt thing... I’ve tried to explain it to you before but you go on hoping and asking again when it is a futile hope. No matter who you ask or how often you ask the answer is always going to be the same. Tuning out salt tunes out small gold.

For me there are almost zero questions left about the Impulse AQ. Except for silly stuff like will it leak? 🙂 But the performance parameters have been pretty well laid out already as far as I am concerned. I suggest you go back and read everything over from the start in the last half dozen threads.

      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.
