  1. I was doing just fine until I watched “Gold” on Stan 😳
  2. We should be allowed to carry a 9mm pistol if prospecting remotely………it’s a long walk back to camp for the 30.30
  3. Sorry slightly off topic…… but undercooked detectors seem to be happening more and more these days……I wonder why? Is there a rush to bring their goods to market to head off the competition……not everything can be fixed with a firmware update !
  4. Well in that case, I shall head down first thing tomorrow morning as it’s about a 15 minute drive for me 👍
  5. Sensational little machine with plenty of power and sensitivity when you need it. You can swing this detector all day with little effort especially in conjunction with the 6” Shooter coil. Highly recommended.
  6. Hello Clive, Regarding the problem with 22K big gold (and 18K to an extent as well)…..I’m sure this is tied in to the AQ’s low pulse width which needs to be longer in order to fully energise these class of targets. I’m guessing a long pulse width and very quick delays don’t play well together?
  7. Clive, Who makes that coil…..is it Fisher’s or from someone else?
  8. Thanks Joe……I suspect the pulse width may be quite low, maybe in order to run those crazy low pulse delays? HH Tony
  9. Does anyone know what the TX pulse width is on the AQ ? I know from previous experience and from some PI machines that I have used (and currently use) that longer TX pulse widths are important to energise the bigger gold rings (which can also be the higher karat ones as well). Typically, greater then 300 uS is needed in order to “light these targets up”. Furthermore, quicker pulse delays are not essential in seeing these bigger targets as the decay drop-off isn’t so pronounced when compared to the smaller profile rings. Tony.
  10. Thought I’d respond to an oldish thread…… The Coiltek Goldstalker 22” DD is bundle wound which helps keep it at a relatively light 1100 grams. Compare this to the smaller but heavier Minelab Commander 18” DD which is around the 1350 grams….ouch. I have recently started some lower beach detecting with my SD2100 and 18” Kevlar Mono coil…..the results have been staggering with some seriously deep old gold rings and “other” stuff. The big monos can suffer from EMI so I am looking at a getting a big DD coil. Anyone care to guess if the big Goldstalker can sniff out the deep stuff and block EMI…….I’m guessing it might be an okay combination. I’d love to get the 18” mono performance without the EMI problems . Thanks Tony PS…Tried the Detech Ultimate DD but being spiral wound made the SD a bit too chatty.
  11. The orange battery case is a third party 3D printed case that holds 3 x 18650 Lithium cells. No need to spend $$ on AA batteries and the run time on Lithium cells is just massive 👍 I will let you know if ever I decide to sell her…….it would be a sad day for me. I have to thank “Karelian” who kindly sold it to me…..he has one as well in as good a condition. Regards Tony
  12. Definitely one of White’s finest machines……I got mine from an awesome chap on this forum 👍 It is still in mint condition but because most of my detecting is beach/water and prospecting, the XL Pro doesn’t get used much. She comes with four mint coils as well (managed to buy a second Royal 800 coil locally). Tony
  13. I’m fairly sure that some 4x6 Shooter coils had a history of overloading across different Whites detectors but don’t really know much else. I think the “V” rated coils didn’t have this problem?
  14. Hello Dave, Here’s the link for the 3D printed battery pack https://www.ebay.com/sch/sn0wboarder/m.html?item=284510484925&rt=nc&_trksid=p2047675.l2562 Stick with the 11.1v (nominal voltage for 3 x 18650 cells). I don’t recommend the 14.8v setup as the extra heat on parts of the PCB is really high and you are only gaining somewhere between 10% and 15% depth increase. The TDI BeachHunter is an awesome “beach” detector but submerging it will eventually cause a leak as the O-Ring and screws are a bad design. You’ll crack the plastic tabs on the case if the screws are even slightly over tightened. Other than those avoidable problems, she’s a beast of a beach detector.
  15. The AQ is in the Intensive Care Unit on life support……the kindest thing would be to switch it off.
  16. 44C weather over here in Perth tomorrow…….I don’t care what’s under the tree but what’s in the fridge and freezer 🥵
  17. Okay, my unit has only seen seawater once but I know of another old Seahunter XL500 that has had continual and sustained use since 1990……and the pins are like new on the bulkhead and coil cable end. Come on Fisher…….it’s not Rocket Surgery or Brain Science 😜
  18. According to his website……..Gary charges……….wait for it…… $900 for a 3 hour lesson 🤩 This equates to $5 per minute, so you owe Gary’s client $25 😀 But Gary provides the “sunscreen and refreshments” I'm hoping that means a $500 bottle of Moët? I wonder if I could undercut Gary 😇
  19. You’re right Steve…..the word “sad” summarises the situation exactly. But this thread is a good, healthy and robust one……who knows, it may spark Fisher into action. I’m sure there’s some lively discussions within the Fisher board 👍 That old saying “build it and they will come” is only valid if it’s built properly. My positive spin is…….Fisher will revamp this model starting with the mechanicals and then refine the code (this is a digital platform?). Most of the work has already been done……they could still hit a home run. Simplify it, toughen it up……..saltwater is an unforgiving environment and will expose any design flaw or weakness. Put this thing in a clear, thick walled polycarbonate case with proven hardware controls that can be easily maintained………sound familiar ? Fisher……here’s a clue.
  20. I can’t see the AQ coming back from this reputational damage……..in any form. Sounds like it’s dead in the (salt) water. To sink a lot of R&D and money on a half assed job is quite unbelievable. So as I see it…….Garrett has the market all to themselves with their Sea Hunter MK2 👍
  21. Great post Skully…..and as I have mentioned before, delays of 20uS still see the higher karat gold rings very well (especially the bigger ones). The day I stopped trying to always run low delays in the wrong conditions was a turning point for me…..and I started hearing the deep gold because the smallest of threshold variations were targets and not the salt and black sands.
  22. Yes, the TDI Beachhunter will leak on you…..consider it for all conditions except submersion. My view on this model is it has a good brain but bad body……bit like my first girlfriend. 😜 I used a rubber discus that I zip tied to the coil…made for a good coil weight. In the end, the coil size in the water and it’s tendency to like to drink (bit like my second girlfriend) was just too much so I moved it on and got more than I paid for it 👍 Running the 14.4v Lithium battery improved overall depth by about 15%…..my records show it as the deepest seeking beach detector that I have used. Extra voltage does generate more heat on the board so bear that in mind. Tony
  23. I just feel that whilst developing the AQ, they should have kept one eye on the basics of some of the high performing PI detectors of the past……proven design, engineering and performance. If it ain’t broke……well you know the rest.
  24. Okay…..just read some other posts and it appears that running higher delays is not a solution. Safe to say that the best pulse machines are no longer made 😩
