  1. Given that FT gave the world a “peek” at the AQ last spring at the outdoor “Messe” in Germany, I tend to doubt that they would want to have it appear at Detectival or any of the other rallies in Europe this September. It isn’t ready for release - we know that because it isn’t released. Showing it anywhere else would likely just stir up questions.
  2. Mike Scott of First Texas will likely be there, but whether he will have news or not ????
  3. No news – hopefully that’s good news! No news – hopefully that’s good news! First Texas is being very very careful about putting out actual information about their progress.
  4. GB on you are getting two channels of signal processing - it is normally noiser than GB off. Noise cancel, reduce sensitivity get away from emi sources like light dimmers, WiFi, cell radios, power lines and transformers. If it still goes berserk, you may have an issue.
  5. Here’s what I posted on Dankowski a while ago... I have puzzled over this question for a while - what are these “steel” caps made of. After wasting an hour on the web I have concluded that it is likely that they are “Tin Free Steel” or TFS. This differs from “tin Plate Steel” or TPS by the use of metallic chromium instead of tin in the laminate. TPS is what most cans were made of - TFS is used because of its superior anti corrosion qualities and its suitability for painting or other decorative exterior finishes. Tin Free Steel Features TFS has excellent lacquer adhesion properties allowing use for food cans, beverage cans and general line cans. Excellent resistance to black sulfide stain makes it the most suitable material for making fish cans. Even when the same surface finish as TIN PLATE is applied to the substrate steel sheet, it provides the unique surface luster characteristic of metallic chromium.
  6. It would be interesting if Plexus, who actually makes this thing does lot sampling testing for waterproofness, No doubt 100 percent testing would be silly, but surely there is lot sampling to ensure that the previously qualified design and assembly are production ready - as well a subsequent lot sampling to assure that there has been no deviation from the qualified process. Of course - we are very unlikely to get that information. Funny though, when I was responsible for contracting to supply hardware to a customer or subcontracting for the purchase of hardware, the terms of the contracts were carefully drafted to specify initial qualification testing and ongoing lot sampling testing - including the steps required to re-qualify the processes in the event of testing failure. Of course rocket engine valves which flowed 3000 psi liquid hydrogen cost a lot more than mass market electronic devices. I consider it likely that Chase’s summary of the situation is correct and that it is a sort of “infant mortality” issue - but the 3 year warranty will allow ample time to see what is really going on
  7. Interesting theory - if it doesn’t leak in dunk 1 or dunk 2 - you are in the clear. Time will tell if the theory “holds water” or holds it out.
  8. The good news, if any, is that the tweaking of the electronics and software have been ongoing while all the other hundreds of details of getting the thing produced are being sorted out. For example, LE.JAG has posted about improvements to the depth in the iron ID modes so that now the depth penalty for using these instead of all metal has been reduced to a very small percentage. Since they announced long ago that a gold nugget PI was next in line, I would expect that this platform’s development has moved along so that the gap between the introduction of the “Aqua” and the “Terra” might not be so long.
  9. Skate, The Impulse is on the whole slightly less “fussy” than the TDI (I have had two of those). The controls are similar, but there are differences. One big difference is that there is no huge depth penalty like is found in the TDI when the TDI is in GB on mode vs. GB off. Below is a photo which was released after Fisher brought a proto to the Huge Outdoor Expo in Germany. Here is my best shot at explaining how it works. Please note that l have only used a prototype and that only for a few hours per day over three days. Volume and Threshold are pretty self-explanatory. Likewise Sensitivity operates pretty much like on any other detector. The two smaller knobs at the bottom are - on the left, the on/off, Batt test, noise cancel, all metal and two discrim modes - mute and tone. The right hand one sets the noise cancel position when in noise cancel and the pulse delay when operating in all metal or one of the two discrim positions. The start up routine is turn on to noise cancel, then rotate the right hand bottom knob till you get the quietest audio - there is no stop, it’s just a rotary encoder. Turn to all metal and set comfortable level of sensitivity, threshold and volume. The Sat Speed works much like the SAT or recovery speed setting on a VLF, longer signals with more depth perhaps or shorter ones to enhance the discrim function if you are using it. The Iron Mask Knob increases the effect of discrimination in the Multitone or mute iron ID modes (selected with the lower left knob). The Pulse Delay control is generally used at the minimum which conditions allow. Some circumstances may require a longer pulse delay to compensate for salinity, running salt water or other factors. The shorter the delay, the more sensitivity to ALL targets, not just to small ones. The SAT and Pulse delay interact to some degree so adjusting the delay may make you want to tweak the SAT. Unless ferrous junk is a serious problem, all metal is the quietest mode and the most straightforward to use. It also has the max depth (although the sensitivity difference between it and the ID positions has been steadily reduced as the successive prototype revisions were developed). LeJag, who has been the chief development tester, hunts in all metal and finds that he seldom needs to cross-check in discrim. - but he has been using PI’s for a decade and is an ace. In my limited use of a prototype last October in San Diego, I found the all metal or the iron mute discrim mode to be the most comfortable for me. None of the settings are super critical. The
  10. On the general topic of the Impulse/Manta not being ready for product launch, I think Olson Wells summed it up long ago OK - I swear the AQ ain’t no cheap California wine, but the classic Olson Wells commercial for Paul Masson, is probably in line with the thinking of the “gnomes” in El Paso. When it’s ready, it will be ready. Hope the "Finish" is as expected.
  11. Leaky cases are always a critical failure in a waterproof design. I have no idea if the supposed case leak has anything to do with the slow pace of final pre-production development at Fisher - as Steve said, Fisher is “leaktight” (lol) on the subject of the Manta/Impulse! Here’s some stuff on leak testing waterproof items from a major supplier of testing services and hardware. Here’s some stuff from the biggest testing company in the area of leak detection of electronic devices. This shows the two-step test. A container with the device in it is pressurized to a given level. If that pressure decreases, i means the air has leaked into the device (the interior of the device is at ambient pressure to begin with - a pressure lower that the level the chamber is pressurized to. pic upload upload photo to internet for link [www.cincinnati-test.com]
  12. It's simple. Gold is rare. It is incorruptible -never corrodes or tarnishes - eternal.
  13. There’s always the possibility that they just couldn’t get the bloody things to work! Lol
