AQ Owners, How Stable Is Your Machine In Salt Water?


Recommended Posts

Yes, According to what I read. The 11.5 setting was actually a last minute change to 15uS. Because of this last minute change, I'm assuming they knew a problem existed for working submerged in salt water. Out of the water on the wet sand beach, this machine is great.  Working here in Pensacola, in the water, A lot of the modes are not able to be used to the fullest extent with the 12.5 inch coil. I'm looking forward to trying the 8 inch coil when it is available to see how much of a change it makes. I do realize this machine was designed for use in the wet salt sand at waters edge. the capability of the machine is limited when you enter the water with the 12.5 inch coil.

PI detectors are for when a VLF won't produce. If a VLF produces... why use a PI? To dig extra junk? I tell people all the time - use a VLF when you can, and a PI when you have to. There comes a point

I’ve heard of some people experiencing issues, but nobody seems to want to say anything publicly about it. So it goes on via email or PM. I don’t understand that myself. Are we concerned about hurting

I am currently checking with the customer if it is not a problem with the coil... Thanks for your messages ! 👍

It is not because there was a problem that one put 15us, it is simply that Steve has recommended it to me in a conversation, so I programmed it for safety. I'm publishing a video today on the forum to show the normal behaviour of the system in the sea water...

I have got it to work in Destin Florida in open water at sea

but it was very calm and even with a slight under tow,  but once conditions changed it was the difference in night and day or Heaven and Hell.....out of twenty hours Submerged in high salt salinity The big coil or at least mine did not like Salt I could make it work but at the cost of extreme depth......in brackish water I can make it go where Others can’t get to. It will find gold that all machines miss......but heavy salt now ....I got three good hours most these finds below Blue preset....in the other 17 hours. I am still learning this machine but realize I am very good at what I do in submerged water.

Thanks Jim. How do you think a smaller coil would do in heavy salt ?  I would love to see a coil around 9.5 inches providing the 8 inch coil provides a lot of improvement.

I use to hunt and dive Pensacola Beach ( over a hundred year old beach) back in the early eighties there is Always waves and gold in PB.....I will say I was one of the first to hunt a lot of the golden sites in the area....earlier I use to surf hurricanes me and My brother would hide in the dunes with few  friends and wait for the curls to Break jon top of each other we would just jump from one wave to another aaaah the days of adrenaline and Sea foam.....broke many a good board but in that moment you live ten life times.....Still got my old Eliminator 67 one the Beach Boys had on woody wagon .

yes I lean towards A 10 

just like my board blue strips and gold brown

Happy Trails

" I do realize this machine was designed for use in the wet salt sand at waters edge. the capability of the machine is limited when you enter the water with the 12.5 inch coil."

This is a wrong assumption.

If the AQ aggressively reacts with the coil in the sea water, the only conclusion is that there should be a fault in the system, most probably a shield discontinuity in the coil or in its lower cable plug.

In that case, one has to report the case back to FTP.

Indeed if you do not get results similar to the videos, you must report it to FTP.

Back in the water today with my new replacement coil. I was unable to get into the Gulf due to the rough water. I was able to get into the sound and check out the new coil. There was definitely a difference today. I went through testing all the different modes and settings. Still was not very stable in the all metal mode. Settings - Sens 3,Pulse delay-11.5, ATS- 10. I was able to get the most stability in the Volcanic Sand Mode. Sensitivity- 5, ATS-9, Pulse Delay - from 7-11.5 uS Usable over the full range. The higher the pulse delay setting, the more stable it is, I can hunt in this mode just fine. Still cannot vary the coil height much while sweeping the coil,but better than the other modes. All of the modes were a little better this time out. Another factor that may be involved is we have had lots of rain in the last week. Im looking forward to trying it in the Gulf when the water calms down. I am still unable to use the full capability of the machine in the other modes. I still think a smaller coil will help in the other modes.

We have proven that the AQ in normal operative conditions works well in salted water even if there were some doubts about that.

There are now a number of AQ users operating the system in sea waters without any problem.
Also, the sea water in Florida is not much different from other parts of US coasts and Northern Europe coasts.

Thus, we must conclude that there is a specific problem on YOUR  system (and maybe on another one, who knows?) .
 

Making a diagnosis of a problem needs a systematic procedure to eliminate the potential sources one at a time. The one left is then the probable reason why it does not work. it is then still time to find the cure.

Let's make an elimination procedure together:.

1. With the old coil, you have reported that the AQ was unstable even over wet sand. Do you confirm?

2. With the new coil, what is the behavior of the system over wet sand? Is it different from before?

3. Same when only the coil is submerged and swing  in sea water?

4. Same when the coil connector and enclosure  are submerged in sea water?

5. If the AQ responses in conditions 2 and 3 are  good and the one in 4. is bad, then there could be a problem with the coil connector or its fitting. In order to confirm that, you could plunge the whole system in sea water for a few minutes, then take it out of water and immediately make a test with the coil connector in the air. If there was some salted water ingress in the connector, the system will also badly respond.

6. If the procedure 5. show that there was no water ingress in the coil connector, then there must be a problem with the  system itself. It should be returned to FTP for further study.

7. If there was water ingress, the fitting of the connector was incomplete or the connector is faulty.

In the latter cases, a 8" coil would not be a solution to your specific problem.

8. If the system makes faulty signals when slightly changing the coil height during the swing, there could be a fault somewhere in the ATS circuit. If the system re-calibrates too fast whatever the ATS setting, that triggers a constant re-adjustment. If the system does not re-calibrate fast enough, there are false detection's on every slight changes of ground conditions.  In those cases, there is no other solution than returning the whole system to FTP.

Do you see any change of system behavior when changing the ATS from minimum to maximum values?

      I met up with a local forum member at 1 of my secret spots he has never been to. Conditions were bad , heavily sanded in. We were down in the wet , no mineralization to speak of , hard sand the first 3" then gravel mixture. The hole filled in fast. Keep in mind , my EDC for 30 years has been a PI. Also I used this for only 15 MINUTES. Here is what I found :
      I buried a small size 4 ladies 14k , 2 gram diamond ring about 12" in the hole and filled it. Myself being tall , the shaft was fully extended. Immediately I knew it was not long enough and it had a bit of a wobble. Did not feel steady because of that. Ergonomics seemed good and the coil felt light , so that was great. Now... the only settings I messed with were changing the modes. I didn't even look or ask what my buddy had those other settings on. I just wanted to get a feel for the machine and see if it had any discrimination. I tried 3 different modes when I swept over the hole : all metal , tone , mute. All 3 picked up the ring loud and clear. Then we threw a small piece of iron and a piece of lobster trap wire on top , which was probably about 4" above the ring. In all metal and tone mode , I could barely noticed the difference between all 3 targets. But I could seperate them from different directions. In the mute mode I couldn't. I thought I would only hear the ring , but I still heard all 3 targets. This really isn't any different than my DF. BUT , I do have a sense that this AQ can go a few more inches deeper. 6-8" ? I doubt it. Overall , it's not a bad machine , definitely needs a few tweaks. But I feel what needs more tweeks would be me...🤣 As accustomed as I am with a PI , I know this would take me MONTHS to get down. Let alone probably a good year or so to master. Kinda my short 15 minute hands on review of the AQ. Anyway...our hunt together was fun , even though we only found a few coins and trash. And I got to meet a great guy.

      My question is in the description.
      Does the AQ see all gold as low conductors. I have some big 18K and some mid sized 22K rings that give high numerical numbers on my Whites MX7 and from memory a high tone on my CZ21 (no longer have). I also recall a high tone on a pure gold nugget on a gold chain with the CZ21. I understand that golds conductivity diminishes as more alloys are added to the mix. 
      Will these bigger and higher karat gold rings be “low conductors” ?
      And finally......how does the AQ see platinum rings. I’d hate to miss any of the items described above.
      Thanks for any replies or first hand experience.

      I may have fell out of my tree again because here’s something I just don’t understand.
       You got a Limited AQ selling for 1500 and here come summer you have another AQ that will be selling for over a thousand more than the Limited.
       The word Limited is just referring to the number of detectors made on that run and as we’ve been told that number was 100 .
       What I’d like to know is the Limited ones also limited in brains as one would have to think that justifies the new AQ such a increase in price that goes with it .
       If it’s face is one only a mother could love with a bunch of knobs that okay . I’ve seen some of the best detectors ever made have nothing but knobs. I do have ears and I’ve been digging on sounds for years.
       I thank you ahead because I know somebody out there can answer my question and at the same time reduce the pressure on my brain when I think too hard.

      I just watched the FB live program on Treasure Talk. The new AQ will be released this summer, will have a depth rating of 10', an accessory 8" coil, and will cost $2,800 - $3,500!

      I was wondering if anyone has ordered anything from this company before. I'm assuming my headphones dies on the AQ, so I wanted to get the cable and have someone build me a new set of headphones. This company has the 5 pin M8 connector needed for the AQ I think.  It also has the ones that are "L" shaped which would look to be a better way to have the cable come out of the battery. The video shown sounds promising and the price seems extremely reasonable. Let me know what you think. Will it work?
