Fisher Impulse AQ detector update

[lytle78]

Cfmct

The ability of the AQ to do the required work chest deep in the surf is not known. What waterproof rating it will have, how the coil, rod and cable will behave in that environment - I have no information or idea about. all remains to be seen.

Right now, it is asserted that it functions well at 7 microseconds in mineralized sand, that it has impressive depth on natural and buried targets in all metal as well as both ID modes, and that it is very quiet.

Everything else is remaining to be described and verified.

About small gold, LE.JAG has posted this (elsewhere) in response to questions about that...

“I think it is more efficient on the rings
the ring goes into resonance / a benefit for the pulse
the vlf is better on different shape and probably micro jewelry

note that I mainly hunt the bottom of foreshore
in search of heavy object / sort by the sea
on its areas there is no earring of 0.5gr ....

you have more luck in finding in the water
with a smaller coil AQ will probably do as well as equinox / on this type of target

but I think you'll be more busy with the big deep rings”

Not to pick on the AQ but I see the coil wire placement as a cause for concern.. I can possible see someone hunting in murky dark water and hitting that wire and possibly snapping it off.. most detectors have the wire near the shaft as far as I am concerned to protect it... why they did it that way.. I have no clue but it may come back to bite them.


Depth is not an big issue for me.. we have compressed mud and rock... under that is clay which I can reach with my modded Excal..

 

[lytle78]

Nice spots you hunt! Lol - but obviously it pays off.

If you can reach the “basement” with your excal, then you seem to have it covered. Even the AQ can not be the answer to every “maiden’s prayer”.

Beach detecting is not an “unsolved problem” existing tools do a pretty good job. Selling the AQ will require demonstrating that in a significant number of specific applications, it yields significantly higher recovery of valuable targets. By no means a “slam dunk” - superiority claimed will have to be backed up by superior results.

There is one beach I would love to try it on that a discriminating machine worthless on.. but I don't know if its worth it to be honest... there are 200 bullets dug for every good target. you an hunt this beach for a day or more and go home with nothing but 22 to 24 cal bullets.. this beach gave up 11 gold in 14 years.. I hunted it maybe twice a year when I am bored and want a challenge.

I don’t salt water hunt at all.
I am the one who started this thread.
I thought SOME folks would be interested in this detector that seems one day will release to public.
The ability to it seems disc out iron at depth (or recognize it via tone). I would think this ability alone would be a tremendous asset to a gold ring hunter on salt water beaches.

Maybe I am wrong.
We’ll eventually see.

I don’t think First Texas is stupid enough to basically release a copy cat PI detector and put a somewhere around $2,000 price tag on.
Nor do I think this USA Engineer Mr Moreland would have hooked up First Texas with this Engineer from France had his product not been somewhat worthy in its performance in a salt environment.
And they FT hired this engineer from France too. I bet he don’t work for free either?
He shouldn’t in my book.

All this shoulda, woulda, coulda stuff will be answered maybe when this detector releases and some folks buy and start reporting on.

Will this detector give an EDGE for finding gold rings??
Real simple question. I think most folks who do hunt salt water environment want to know and obviously can afford the price of this detector.
Is the detector more EFFECIENT in the long run vs other PI detectors. At locating nonferrous in the salt environment And the possible nonferrous (gold) comingled with ferrous?

Some older pi units may get knocked off their high horses when this baby releases. I don’t Know one way or the other. It could happen though. So some folks better prepare themselves. Naturally there will be naysayers even if the unit does perform nicely and yes it does give advantage in the bigger realm when seeking gold rings say in the salt water beach kinda enviornment.

Are you sure, this thread got hyjacked along time ago

Are you sure, this thread got hyjacked along time ago

We can all speculate till the cows come home. Pure waste of time. Folks keep using what you have. When this detector releases we’ll all start to see the finds and the actual feedback.
And folks can buy if they want to.
I’ll look at your finds made here on this forum with it.

Remember I don’t salt water hunt at all. But I did take the time to start the ball rolling here on this future model. I hope everyone who hunts in the oceans, etc finds a 5 gallon bucket of gold rings. Maybe one day I will get to detect in the water. Until I do, this forum here and a few others is all I have from now.

So reading here I learn things. So when I do get to salt beach maybe I won’t look so much like a FOOL.

A tester posted on facebook that in disc the AQ loses 10 to 15% depth... I will believe a tester before I believe a messenger...

I have been a beach hunter a long time and used a pulse for many years and I will find gold.. this new detector won't stop that... it won't obsolete any detector out there.. like someone said its a niche detector and not everyone needs or will jump on the band wagon... When the NOX came out some jumped.. some told me to jump... I didn't jump nor will I and yet I do very well with my Excal and saved a bunch of money in the process.. some think if they aren't finding much this will help... its more than the detector.


I know guys who are using pulse machines now that are deeper than this new one on a nickel... any pulse will go deep and those of us who are not afraid to dig deep and know our detectors like the back of our hand will still find gold...



I'm waiting for the Pulse Devil to release..

When I have mentioned a TDI it is because I have owned two of them, the last one is happily finding lots of relics in California with Paul P. I have lots of time in the field with the TDI and understand its operation well.

As far as beach hunting, all of mine was during the 2 years I lived in Yorktown VA. I used my original TDI as well as a Whites DF.

The post above says that their TDI hits 17” nickels at the beach, my last one would hit them at that distance in air tests - with GB off.

Alexandre is now asserting that the current rev of the AQ is hitting 17” nickels in wet beach sand not only in all metal but in each of the iron ID modes.

When it reaches the market everyone will have plenty of opportunity to either try it themselves or consider the reports of those who have used it.

At that point, your quote above will be come operative...”I’m a beachhunter and I tell it like I see it....”. You will be able to see it - then you can tell it.

Till then, no one can say if the AQ will run happily at 7microseconds delay on your mineralized beaches. It should be noted however that the testing in France for years has been on very mineralized beaches full of black sand and a type of soil known as Alios here’s a description of the stuff from a Canadian geological handbook - bilingual French/English

iron pan - alios
A thin indurated soil horizon in which iron is a major constituent of the cementing material. Several kinds of cementing materials occur:
I iron - organic matter complexes;
II hydrous oxides of manganese and iron; and
III hydrous iron oxides.

You can clearly see the stuff in the pictures LE.JAG has posted, here’s one

When you have seen it, you will judge - one way or another - till then, your skepticism is understood.

my bad rick yes it was with GB off and in ALL thats does make a bit of differance i should have mentioned that

 

[lytle78]

No sweat BR, From my own experience with the TDI and what so many others have posted about using it at the beach, I figured that GB off was what you meant.

The well known TDI’s depth loss GB on vs off as well as the earlier posts where LE.JAG talked about the AQ being deeper in all metal - have caused folks to sensibly inquire what the depth penalty was likely to be - 10 -20% numbers were indeed mentioned.

The project isn’t standing still however, waiting for production and marketing issues to be dealt with. Software (and perhaps other) tweaking

Just for the record, Alexandre’s results posted this week - presumably using the most recent software suite showed the 17” nickel in wet salt sand in all three modes - all metal and the two ID modes, Multitone and Mute.

If all metal is still deeper, guess he will have to try 20” and see! Lol

 

[lytle78]

One word (or three) about what tnss has posted.

“One Trick Pony”. (I said “about” what he posted - tnss didn’t say “OTP” they are my words)

The AQ is ruthlessly optimized for gold jewelry at salt and even highly mineralized beaches. That doesn’t mean that it can’t do anything else.

In my VERY short time with it I used it in dunes near Yuma and in washes and on the flats here in Gold Canyon (Phoenix area - foot of the Superstitions). It behaved very nicely thank you. I didn’t have time to do any real testing, but my observations were that it was comfortable and quiet over the ground. Our pretty positive red hot rocks sounded off, but the Iron Mask control could be adjusted to deal with them. I have no data on how that affects depth or anything else, but I became somewhat confident that - for hunting for low to medium conductor relics in iron ID - or hunting for everything in all metal in anything short of extremely mineralized ground - it would do just fine.

So, my bet is that the AQ won’t in fact be a “One Trick Pony” -

But, as always, we’ll see when we see it.

Just for fun, here’s a pic of me playing on the dunes near Yuma - on the way back from San Diego. The high tension lines caused no problem by the way.

 

[lytle78]

OK, now I’m in sand dune mode. I have way too much experience driving ordinary 4X4 vehicles in remote desert tracts, including in the world’s biggest sand desert - the Rub al Khali in south east Saudi Arabia and into Oman. Mind you, I said experience - gained over 12 years living in Arabia - I didn’t say skill. Maybe the pic will explain why skill is hard to come by. Near noon, winter, Rub al Khali, about 50km from the nearest access road (yes, that’s me - scrambling to get out the sand ladders, all the straps and ropes we have - so that my pal in the only other vehicle can help rescue me from my screw-up)

Well, seems in the pic you got the sand. Add some water and bikinis and you’re all set. Lol

Don't see any bikini's , don't see any water, i see the wrong vehicle for the job, a big foot, or dune buggy was the ticket PS Rick not cutting a machine down, we will all know when it hit's the market, my problem is i have 0 patients , i guess waiting for the Equinox , than another 6 months for the 15 inch coil , i have thin skin, it's the wait , that get's me , and the hype just make's it worse, happy desert hunting.

Earl, you must be one poor doctor.
You don’t have any patients.

Ya

Being a professional driver for 33 years , i would say he's over weight , sand , and a lot of hot air could have been the cause howboutit , , Ps it look's like the tires are full of air also, guess he didn't know to let out a lot of that hot air before venturing out ya figure he lives in AZ , he should know better Tnss it's been since 1978 since i went to school, my spelling is bad, who care's

 

[lytle78]

I had about 12 psi to start - 8 or so on the extract.

Bad judgement driving when the sun was high, need sun angle to see the sand contours. The vertical shadows in the pic give my error away.

The tires were special Sumitomo “Shaheen” sand radials - Shaheen is Arabic for falcon (anything named Shaheen sells big over there) - The Sumitomo agency set me up with a nice lunch with the visiting engineering team from Japan. They explained how the tire belts were designed so that as the pressure was lowered, they didn’t just get “fat” - that the belts relaxed to longitudinally extend the footprint. I guess that my purchasing tens of thousands of $ a month of vehicles from the GM dealer might have had something to do with why I got invited to lunch - perhaps.

Anyway, it was a long time ago - the Suburban was a new ‘92 - first year that 4X4 Suburbans were available with the 454 Big Block. On the way down from Riyadh - 800 miles or so, it was new two lane blacktop - no traffic, no cops. Set the cruise control to the spot that the GPS on this arrow straight road said we were going 100MPH. A stop occasionally for fuel - and we FLEW!

Now, if that sounds like bragging - well, maybe, but old pal SM - be careful who you tickle!

You may have driven for 33 years - you have my sympathy, but if you have never driven hundreds and hundreds of miles of the back of beyond in a day or two including deep bad sand hour after hour, then your 25 years too late advice is worth zero. Thousands of us who lived and worked in Arabia have done it, learned the hard way. Some lost a vehicle in a bad spot now and then to return and find that the Bedouin had touched nothing - they are funny that way... Oh well. I digress.

Was a good block, but a gas guzzler , those Suburbans , if they are like the Excursions , they have the heavy duty frame for towing with a stiff suspension , i am a Mopar guy , have the 5.7 hemi 2500, had a 69 383 Roadrunner, might get a Hellcat red eye for kicks, but i here Dodge is bringing back the 426 hemi , 2021, might wait, they also might put that motor in the 1500, just kidding about your air in the tire's , i wanted to see what you come back with , i have a buddy in Vegas , is there any gold nugget's around him ? if not were does he have to go to get them ? , Earl

Here’s some data from the designer of the AQ - Alexandre Tartar - who, by the way is celebrating his 2nd anniversary as a Fisher/First Texas employee.

Since the D forum is the only place Alexandre has posted about the AQ, i will cross post something he just put up - under the “handle” of “golden retriever”. He posted it right after D. had made a post where he commented that the Tarsacci was hitting a nickel at 14” on the beach.

Note: English is not Alexandre’s native language. Also, when he writes “(with a fast swing without noise)” he is not talking about the strawberries, but about the fact that all the test results he is sharing were obtained not by “massaging” the target, but with a fast swing and that was without any resulting noise from the ground. The Tone Mode and the Mute Mode are the two modes where ferrous and other high conductor targets are ID’d.



Hello,

Salt wet sand for US nickel :

IN ALL METAL MODE 17'' without noise at 7µs with a maximum ferrous discrimination

IN TONE MODE 17'' without noise at 7µs with a maximum ferrous discrimination

IN MUTE MODE 17'' without noise at 7µs with a maximum ferrous discrimination

With fast or slow SAT speed setting...

If the competition is better I pay them a tray of strawberries... grinning smiley (with a fast swing without noise)

Alexandre

Check what I highlighted in bold. All were 17" on the nose? It is not a question for you. Since you did not use it you can't answer it. Adjusting the SAT was no depth gain or loss??? It is a question to ask yourself...

Either way have a safe vacation...

As for 17" in wet sand, yea I have 3 machines that can do it. The 4th did not really test. Giving a high tone for "discrimination" I have 2...

 

[lytle78]

I am now back on the main line. Detector stuff only - apologies for the reminiscing - won’t happen again - hopefully....

I think what Alexandre meant was that from the ideal to the least favorable setting of the SAT, the 17” nickel signal was solid. The nickel at 17” - all metal check, multitone check, mute check. Not a test where — how deep can I bury this and still get a signal - different test

If I am correct in this, it means that there is still some “detectability margin” left at 17” on a nickel with the AQ, otherwise burying it at the maximum depth detectable with the optimum setting of the SAT should have resulted in not picking it up at less optimism SAT settings.
