  1. Interesting thought. Since the AQ Iron modes seem to work best with relatively “clean” ferrous junk, it might turn out that freshwater use is interesting after all.
  2. Nox, you are correct about the edge of the coil and it is like a knife blade. That is a function of the extremely fast sampling and integration of signals by the AQ. Alexandre named it HRS - Highly Reactive System. There is no lag when transitioning between targets through the whole system from signal to sampling, integration and audio output when transitioning between targets. This is why it is fully capable, in tone mode of giving both a low an high tone when - for example - a gold ring is adjacent to or even covered by - for example iron nails.
  3. There are some who will work diligently to learn the AQ’s ways. They will then think clearly about what it does and doesn’t do. They will further review all of their experiences on their various hunting grounds - then they will methodically proceed to uncover items previously not recoverable. This is Alexandre’s intention with the design of the AQ. Will it be something which lots of serious beach hunters will be able to achieve? We will see. 8 machines in the wild ......just a drop in the “ocean”.
  4. Sorry your hunt turned out so bad. I suspect that any detector would have struggled in that location. AL nuggets, for example can’t be effectively discriminated out with any system of discrimination I can think of. As far as those large pieces of junk - the non ferrous wouldn’t give a low tone unless they were really big or really shallow. As far as the elongated rusty bits, I believe that when you are more familiar with the machine you will find it relatively easy to rule those out as likely good targets no matter what mode you run the AQ in. I suggest you get some rusty nails, some large bits of rusty junk, some pull tabs, some coins, a few gold rings and find a place in your yard or a nearby bit of open ground and start learning how the AQ works on targets you know the identity of. It’s all about sound - you have nothing else to go by. The key to success with any “audio only” detector is learning what good targets sound like and then go hunting where good targets are likely. Sounds like your site for your unsuccessful hunt has - based on your prior experience there with other machines - a very low probability of recovering a piece of gold jewelry. Add to that, your unfamiliarity with the performance of the AQ and I can understand your frustration.
  5. 4 of the deliveries were made in the last few days - let them at least unpack them!!!
  6. Tom, the golden barrel cactus have always been my favorites!
  7. I think that Alexandre’s last line (fresh out of Google translate probably) is a reflection of the fact that digging earring backs, foil bits, tiny pellets of melted aluminum bonfire trash is a total waste of time. The AQ is for serious HUNTERS - folks who expect to find gold in serious quantity.
  8. LE.JAG, Am I correct that you mean that the difference in mass of the light and the heavy ring is what makes the signal of each of them have the same amplitude at the limit of detection, but that the limit of detection of the light ring is a much shallower depth than the limit of detection of the heavy one? That is a good concrete illustration of the fact that the audio level is a factor of the strength of the signal and that signal strength is a function of several factors and that depth of the target is only one of them.
  9. Yes, the plastic case knocked a couple of pounds off Compared to the Aluminum one. Somehow I ended up with 3 of the Goldtrax units in the gold boxes with the elliptical coils - need to sell at least 2 of them
  10. Yes, the audio is modulated, the stronger the target’s return signal, the greater the audio intensity. The strength of the return signal depends on the target characteristics including the distance from the coil (depth) composition, form factor and mass.
  11. OK, normally “cross-posting” is frowned on, but some pushback on another forum and a bit of me protesting that it was a bit “personal” resulted in a more or less graceful withdrawal by the other party. It made me think again about what the heck I am really doing with all this and while waiting for dinner, I wrote this... Now, XXX with your permission, we’re pals again. I ain’t “pushing” nothing. I worked my buns off for three years because I believed that Alexandre Tartar - by virtue of working day and night for MANY years had made some of Eric Fosters ambitions for the utility of a two channel PI detector into a an amazing beach jewelry hunter. I have never wavered in the hope. That hope has turned into a belief and the belief has turned into a conviction. I have probably spent 20 -30 hours on Skype calls with Alexandre. I have use two prototypes, starting in October 2018. I bought (by invitation) the first production unit - which worked great - only to have a request to return it and have it replaced 6 weeks later. Meanwhile, Tom Walsh, listening to some small amount of feedback, decided that he really wanted it to be simpler, more robust and have longer lasting on battery. What to do - he had about 100 units kitted out and he could easily afford to scrap them, but he had a better idea. Bothered by folks like me and the designer, Alexandre and against the advice of his marketing staff, he decided to launch the thing. It would be the AQ “A” model, which was what it ought to have been called - but none of us were bright enough to see it clearly in the light of normal development in, for example military aerospace development - so he called it the IMPULSE AQ LIMITED. Tom ain’t broke. He wrote the “Disclosure” to explain what he was up to. 100 more of less - for sale at roughly half the price of the eventual AQ “B” - sold by one easily persuadable chump - yours truly - and saddle this fool which the entire management of the AQ “A” public facing existence. I make a few bucks per unit - Fisher does direct ship and provides the warranty and I have the responsibility to find the early buyers who will make the most immediate contribution to the collective knowledge of how best to use this thing to extract the maximum gold from beaches. I understand why this approach is hard to classify. Is Tom merely trying to make some bucks flogging second-rate hardware? If I believed that I would have withdrawn from this discussion with my tail properly between my legs, In fact I am proud and enthused - that Fisher figuring out that this thing that they had ready to launch - could be much easier to use and maintain with some mechanical changes - but that these would take time. And realizing that this thing would IN ANY EVENT require a careful and managed introduction to the niche marketplace represented by hard-core beach hunters - decided to use this early production version as an “AQ-A” model and offer it at a “not to be repeated” low price, to enlist the kind of die-hard beach hunters whose use of it would make or break it. I am not embarrassed by my participation. I think that this launch is innovative and probably unique and i am pleased to be involved.
  12. There is a thread about this over on Dankowski. After having some muck slung at me by someone over there, who, among other things accused Fisher and me of palming a “Prototype” off on the public.
  13. Facebook is eternal I guess. Plus I suspect Des would be OK having his video live on. He has a bunch of excellent videos on his channel. Desdunne1
  14. Dave. In Tone or Mute mode, the reject control sets a “balance” point. This Is a point along a time line, All signals are analyzed by how quickly their signals decay. Signals which decay quickly fall on one side of the balance point, signals which persist longer fall on the other side. How long signals persist is based on a couple of factors. Chief among them are the conductivity of the target, the magnetic characteristics of the target due to ferrous content and the mass of the target. In tone, the AQ gives a high tone to those targets on the “left” or short persisting side of the balance point. It gives a high tone to those longer persisting signals which fall on the “right” or long persisting side of the the balance point. Signals which decay quickly and therefore are assigned a high tone include gold, aluminum, brass, lead - but only until their mass becomes so large that the signal persists beyond the balance point - in that case they fall “beyond” the balance point and would give a low tone. A big piece of aluminum will give a long persisting signal, as will a piece of silver or a nail. In the first case, because of its mass, the second because of its conductivity and the third because is is a significant ferrous object. This is totally different than the operation of a VLF detector which uses phase shift to do discrimination.
