  1. Finally decided on cable connector, got it quick from Mouser, and made an AQ to GPX adapter, and hope to try it in a couple days! The shaft pins are 90 degrees off so it might move around and get annoying. I’d prefer it were longer too - the stock shafts are about 9” longer. Any suggestions as to where to get the one I need?
  2. As I’ve said on some other thread, it seems one of the AQ three coil connector pins is unconnected (it’s very loose). I know which is P and which is N. I can’t get my connector’s housing off to see without the likelihood of breaking the base connector. It just won’t undo. I discovered that my Beach Hog has shield connections that I probably missed on my gpx to AQ adapter.
  3. Hi guys, So I’m a new AQ owner and think I better protect the connections with some kind of tape or whatever before I approach my local beach. What do you guys recommend - the reviews of some tapes on Amazon are pretty bad.
  4. hello, is it possible to adapt a detection disk for a minelab gpx on fisher's impulse aq, thank you
  5. A warm rainy day nothing frozen so I took the AQ to a fresh water beach I have been to countless times. After about an hour I heard what I was listening for a quick quiet targetI took one scoop and checked the hole it was still there, now I become more interested as a lot of the time the weak sounds are small lead fishing weights which are down about 4 inches. a few more scoops and it was out.
  6. I think this topic needs to be lightened a bit .... the price of the detector is one thing ...- which should express the possibilities of the detector ... I would be interested ... if Mr. LEJAG ..., ... Geotech-Carl Moreland, and other members of the Manta-ImpulseAQ project ... or the Tester who is currently testing IMpulse AQ could write something about the possibilities of the Impulse AQ detector. lately, all the comments revolve around the beginning of production or prices .... let's talk more about what this detector can bring to the world of detection .. In any such project, positive thinking is important both on the part of the designers .... as well as on the part of potential people interested in this PI detector. Fisher Impulse AQ metal detector
  7. I agree!! I seen the issue from the start with the AQ, even on the excalibur. In fact all waterproof headsets are weak in the audio department. To be 100% they must make them reliable, which can be very restrictive on the piezo bender. So make your own, all they have to be is water resistant, taking a dunk once and awhile is no problem. And they are easy fix if something goes wrong, since you made them. I have shared this before with others.. and had the same results as Alexandre
  8. I have only been able to use the AQ on the beach for about an hour. With the original headphones I struggled to hear the differences that the Masters of the AQ talk about. I could hear the double beep on the rusty steel, but the ramp up and ramp down and the soft edges vs the defined edges, I just could not hear it. Then when I went home I tested targets for hours. Pennies, nickels, quarters, screws, bolts, tent stakes, copper rings, silver rings, platinum rings, gold class rings, tiny engagement rings.........etc, but I could not hear much difference. I assumed that I was going deaf and scheduled an appointment with the Audiologist for January. Today for the first time, I put a set of custom homemade headphones onto the AQ and let me tell you what a difference it makes. The ramp up ramp down was all there. The sound chop off when the coil was leaving a ring was so distinct you could tell with your eyes closed if the object was a ring or a nickel. It was my wax on wax off moment. Really excited to take it next week to the beach and see if the backyard transfers onto the beach. I want to sincerely thank the forum members who have been so generous with their knowledge, experience and recommendations. Merry Christmas to all and a safe and Healthy 2024.
  9. When and why would you use the 8" coil on the AQ at the beach? Is it strictly an in the water coil or does it have uses on the wet sand?
  10. At the right there is the option for captions then at extreme left, autotranslate then scroll down for English. Not all clear / accurate but decipherable for anyone who wants to do a deep dive on this detector. So its "Cog,"( settings) Subtiles, then Autotranslate, then scroll to English. Yhis is part one of two. --the seond one comes up at the end. Brilliant man gotta love him... cjc
  11. EMI rejection seems to have an issue when moving from All Metal to Tone mode. [Major Edit] I removed two videos that were testing in my garage with too much EMI. Better depth discussions later.
  12. I set a bunch of different targets out in a small area in my backyard to test with my AQ. Things don’t seem right. I don’t notice any difference if I vary sample delay. The ATS seems to determine the low/hi tone transition in Tone or Mute modes. Perhaps you have a simple test for ATS, sample delay, and Reject control behaviors?
  13. Sorry for the false alarm earlier in the week, but suddenly I discover that Kellyco has an unlimited number of Impulse AQ Limited detectors for sale. Apparently they ship out from Fisher in Texas. Get them while they're hot!
  14. Kellyco has a small number of Fisher AQ Limited available for the price of $1999. No additonal batteries available at this time and yes that is a $500 price increase from the original price for the AQ Limited. My question is does this mean that this is it for the AQ or will the Fisher AQ Unlimited finally be offered for sale? Interesting, very interesting.
  15. Couple hour hunt yesterday brought a little surprise. I rarely get chains, let alone this small. Was about knee deep in the wash and the AQ hit on this one. Did not come up on the first scoop but did on the second scoop. ATS at 8 and delay at 10.5 to quiet things in the water movement and the chain hit very well. No good way to know how deep it was but when I got home and did an air test the chain is heard well on the AQ at 4 inches; all metal. In the picture it is next to a dime I dug today. Not sure if I hit on the clasp or the little balls on the chain. I tested it with the Excal and need to be about an inch or closer to the coil to hear the faintest indication in all metal and scraping the coil to get it in disc mode with disc set on minimum ... it nulls at 1/2 an inch and nothing at an inch in disc on the Excal. Markings in two places say 925.
  16. Was out detecting today and came across two others detecting. One with a Manticore and one with a Deus 2. The guy with the Manticore could walk right up and we could talk and not hear the other's detector. When the guy with the Deus 2 got about 30 feet away I started hearing his detector in the headphones and by the time he was 7 or 8 feet away I had to turn the AQ off until we were done talking and we got some distance between us. The guy with the Deus 2 said he was not hearing the AQ as he approached. Not a big deal ... just a data point.
  17. Looks like Fisher was able to do some great iron discrimination with the Impulse AQ pulse induction detector on larger gold targets. Does anyone know if this ZTS technology is moving forward or if there was a problem with it's actual performance on in ground targets. I do like the presentation with the rings and nails together.
  18. The new Fisher Impulse AQ is doing something new with pulse induction discrimination. I think I have a pretty good idea of what the engineers are up to and so want to pass on my thoughts in case it will help people have a better idea of what to expect. I have posted numerous articles in the past about coin detecting with ground balancing PI detectors. GBPI detectors split targets into two classes depending on the ground balance setting. The two target classes exhibit by different tones. All Minelab PI detectors do this, as do the Garrett Infinium and ATX, plus the White's TDI series based on the Eric Foster Goldscan. White's on the TDI labeled these as low conductors and high conductors but that is not actually accurate. They are items with a low time constant and items with a high time constant as measured on a pulse induction metal detector. For more on signal decay and time constants see the excellent primer by Reg Sniff Understanding the PI Metal Detector. If you could measure the time constant of the various targets and line them up you would see size has a lot to do with it, small items versus large items regardless of composition. White's TDI "Target Conductivity" switch (notice ground balance on required) I caught on to this fast with the Garrett Infinium in 2004 and Minelab GP 3500 in 2005 and when the time came it was I who suggested the tone switch be incorporated into the White's TDI to allow the user to choose between one of the two classes of targets. Plus the TDI allowed the operator to directly set the ground balance, creating a crude discrimination system for savvy operators. It is actually possible to coin detect with a TDI and dig almost no trash, but you lose its PI depth advantage by setting the machine that way. I preferred using the tones with full depth settings myself with excellent results. The two target classes vary depending on the exact ground balance setting, but generally one one hand you have low conductors and small ferrous targets, and on the other hand coins and large ferrous targets. This means if looking for small gold you dug all manner of small trash including small ferrous trash. Coins were better but you would still dig large nails and other large ferrous items. The TDI allowed a person to advance the ground balance to where most ferrous trash could be eliminated while still getting the coins, but the setting was so close to the coin range to do this that depth suffered as a result, and so was no better than a decent VLF. It's a long read but a lot can be learned by reading the following three links. Coin Detecting with the Garrett Infinium Beach Detecting with the Minelab GP 3500 Coin Detecting with the White's TDI Some Commentary On White's TDI Tuning & Discrimination It can be seen that as far back as 2005 I was predicting that high power PI detectors would find widespread use with beach hunters and relic hunters in particular. That prediction did later come true at Culpepper and other locations. It was obvious to me that this crude discrimination offered more room for improvement. I even emailed Carl Moreland at one time and made mention of the concept of using two ground balance controls to delimit another class of targets beyond the two created with a single ground balance point. But really it is not ground balance, it is just a setting that measures a certain time constant. And that folks, is basically what the Fisher Impulse is doing. It is using at least two dividing points to separate items into three classes, lowest time constant, middle (gold ring) range, and highest time constant The Impulse is eliminating the items with the shortest time constant and the longest time constant and focusing on the mid-range. This eliminates tiny trash and tiny gold, and large ferrous stuff and most coins. What is left is the sweet spot in the middle where gold rings occur plus a yet to be determined range of trash targets. There will be some, that is inevitable, but the vast majority of trash should be eliminated with this approach. This picture shows the result of using the Garret Infinium and separating the short time constant targets from high time constant targets in tot lots. Low constants (nickels and zinc penny plus trash) on left and high constants (copper pennies, dimes, quarters) on right. Notice very little trash with the coins if you dug that class only. But that is deceptive due to the location, which lacked any nails. Garrett Infinium targets separated by tone So take a look at this result from a park, this time only the long/high time constant targets with the TDI... coins and large nails. White's TDI low tone / high time constant targets OK, so let's combine the two to get a clearer picture.... Left of red line low time constant versus right side high time constant targets To reiterate, having only one point of separation presents issues. You get coins but you also get large nails. And the low time constant area is a mess, just way too much stuff including small ferrous. But in areas with few nails it actually works well for coins. The dividing line does vary with the ground balance setting but is roughly about zinc penny if ground balanced in moderate to high mineral ground. The Impulse AQ is basically blowing off the high end to get rid of the nails, and the high conductor coins also get tossed out. Most jewelry hunters will be fine with that - digging coins in the surf is a waste of my time and effort. The AQ is adding another separating point somewhere in that left hand low time constant area, that eliminates the tiny stuff including I assume most wire type ferrous items and foil. Rings due to the round shape with a hole read better than most of the misc trash in the photo. However, some of those items will read in the ring range so do not expect the AQ to be trash free. Trash that reads close to the nickel range will probably come through, like pencil eraser ends and some tabs that read like nickels. If you think of the AQ as a nickel detector that will probably not be far off the mark. My biggest area of concern is zinc pennies, especially corroded ones. I hate those things but I suspect we will be digging them with the AQ. All the above is just speculation based on everything I have learned using this class of detectors over the last 15 years. I have had no part in the AQ development. That said, I think most of what I am describing will prove to be pretty close to the mark as far as how the discrimination functions on the Impulse AQ. And just a reminder. The Impulse AQ will let you turn off the discrimination to run in pure pulse mode, presumably with no ground balance engaged. It should be at similar to but more powerful than the TDI Pro with ground balance shut off. This will not be good for nugget detecting in most areas as it will light up hot rocks, but for many beach detecting situations should be giving us a detector like the famed Eric Foster Deepstar in a much more ergonomic and affordable package.
  19. Just wondering if anyone has any ideas as to why the threshold pots on this machine keep going and what might be done to effect a permanent repair. cjc
  20. Who is your phone contact at First Texas if you want to discuss anything regarding the AQ you own? Edit: never mind, I finally got Felix by asking for "service". He explained there is no warranty carryover - which I expected. Let me know if any of you open this thing up (take photos!). I fully expect to maintain this all on my own if I can.
  21. Has anyone had their control pod come lose on this detector? Pressed my thumb aganst the panel and noitced that it was moving and not secured. Doesen't seem to be any obvious fix although there's a screw visible at the side of the handle when you roll the foam down. Still works but only an impact away from disaster... cjc
  22. Turned it on and All Metal mode was dead, Tone mode works, 12.5” coil. Tried8” coil and it works on both. Will show video later. Looked at connector pins and see some loose ones. Is this ok?
