It's not a lithium but NIMH here...

WOW, is it gold ? Very good !

for nostalgia ....

We almost disassembled all the parts of the detectors! 😉

This is very good news, I never thought I would tell you that ...

Indeed the detector is so sensitive that it can detect its own cable shielding ... The sensitivity cable area is near the coil...

I use plastic clips, we will make some for the rest of the Impulse series.

There is only Terry left now...

Joe because of the wear on the nibs we both know occurs over time, I always push in with pressure the connector as I rotate the bayonet style locking ring clockwise until it stops dead. This prevents the nibs from pulling the connector in to seat it therefore helping stop the wear and eventually a loose connector. Just for those who have no experience with the Souriau connectors. The VALLON PI also uses them but in a metal version.

We are currently reserving the SOURIAU metal connector for the gold nuggets detector series.
We are currently testing this version for the IMPULSE AQ. We test its resistance to salt water.

This connector would add more than 100USD to the detector.

It would also supress the variation phenomenon when the connector is between water and air.

For those that are having issues, make sure the connector is full seated. Almost has a snap in place..... feel as your turning the Lock Shell.

Researching question and Off subject question....Is the Souriau connector for the coil the ..... UTS1JC142G1P ...or the UTS1JC103P or am I off on those..........Thank You Alexandrea and Willy..

none of that, it's the one: UTS6JC103P

Alexandre.... I was simply pointing  out Tom is here where the ... alleged problem is.  Yes he did do the testing with Carl.... but my understanding is this is a far better machine.  He’s an worked with Fisher for years.  I was attempting to be constructive since several would like to have this machine her.  I’m sure you will work it out. I apologize for stepping on you toes.

No problem

My AQ is no where near that stable in neck deep water. Audio is constantly changing up and down. If mine was as stable as this video I would have no problem.

I repeat my question in another way :

What happens when only the new searchcoil is in the water ?

What happens when searching on wet sand ?

Thanks in advance

Or simply send Dankowski one.  I’ll leave it at that.  I can tell you there is a difference waist to chest deep here in the Gulf.  It appears to be more the hard pan.

Thank you for your positive, constructive and very spiritually enriching message. 

We were eagerly awaiting your comment. 

Do not hesitate in the future...

I believe that Mr Dankowski had the opportunity to test the first version with Carl Moreland.

And he said this is the 2nd best PI detector for the beach he had ever had.

According to him, the first was the Aquastar, which I had for years with retro engineering at the time (just for fun), and which has no ground adjustment, and is at least 40% in below the sensitivity of the IMPULSE AQ on all of our tests.

Nostalgia sometimes obscures reality, but I think any good prospector reacts that way ...

Jim P. - you wrote “my machine is no where close to slight retune of the Mr Tartar kiddie pool or slight sounds in video”

Can you explain what you meant by “no where close to slight return”? - what you wrote is not entirely clear - to me at least.

Thanks

At this moment for surf :

At this moment for pool :

As long as we don't see the videos it will be difficult to judge and find solutions.

Video showing:

- The environment.
- The swing.
- The settings.
- The unwanted phenomenon over a few minutes

Houston we got a problem 

my machine is no where close to slight retune of the Mr Tartar kiddie pool or slight sounds in video .....so if they can manufacture this In unit volume it looks like things would be good for a launch .......the units that are noisy ...two things I always look at in Pi’s is the pinch test .....cross up on center shield pins .....Shielding .....the other board settings would appear manageable with slight tweaks in operator settings...

I am only trying to help there is nothing personal fellow hunters including myself need A Fix they can only report on their experience....I know Pensacola Beach Well ....there is no mineralization.....just Salt and waves....2 in Hawaii 2 In Pensacola so on ...

Finally No one wants To send their units in  They are afraid they will get a dumbed down version ....my coil measured 289 micro henries about 3 ohms ....LOL they are afraid their Ferrari will Be turned into a Hugo......Don’t shoot the messenger....hmmm ... Is that arrows I feel in my back ....just my Imagination ...sounds like a song...

Happy Trails Ps thank you for Video’s feel free to send me the new proto type I will put er thru the grind......    C’est la vie
jimpugh

You are right the swimming pool is not a reflection of reality that's why I made many videos to show you in real condition in the surf. Hoping that this will allow you to see more clearly.

You should have the same retune as on the videos

What Deborah is experiencing with her AQ is exactly what I am seeing here in Hawaii.  Alexandre, please go to Florida and meet up with Deborah.  So she can show you in the real world what is happening.  Otherwise Deborah and I need a full refund on our AQ units.

I'm sorry to hear that your testing experience didn't go well. Have I been told that your experience did not go well at white's with TDI either?

I suggest you send a video to show us the phenomenon and your settings on a wet white sand beach with no volcanic rock below to begin with.

I just spent 2 days making videos to show you normal behavior on a beach with a seawater salinity of 36 PSU minimum.

The beaches here are harder than Florida.
The beaches of Reunion Island where the impulse has been successfully tested are more difficult than Hawaii.

If your detector doesn't works like this, you should notify Rick Kempf. He will discuss with you the procedure to follow.

For my part I recommend a return to the factory for verification.
And I would personally make sure that it gets sent to me for testing and its be work fine.

Le.Jag also goes into the water with his detector up to 1 meter.

As for Hawaii, and its white sand beaches underground

New video in rip current :

This video is finally finished to upload

My AQ is no where near that stable in neck deep water. Audio is constantly changing up and down. If mine was as stable as this video I would have no problem.

If this phenomenon only happens when the detector is completely in water, the diagnosis is not the same as if it also appears as in the video.

What happens when you are not in neck deep water? Have you the same result as the video?

I have been detecting many years, My coil sweep is always parallel to the ground. The bottom here is not perfectly smooth. lots of ripples and dips as you are hunting. I get stability in volcanic sand mode and I am able to vary the pulse delay across the full range. It is just not stable enough in the other modes.

Please, do you get the same results as in this video?

28 minutes ago, deborah195412 said:

I have a lot of deep sand here, but when you vary the coil height off the bottom even a little bit is goes full audio. This is on 2 different machines here. I have tried both machines and they act the same here.

Yes this is quite normal for a strongly sensitive PI, just vary the height less than less 1 inch to get a signal.

I showed it in the video below, as soon as I searchcoil is not parallel you have signal.

It is a matter of habit, it should force you to swing parallel to the floor with a lot of regularity to obtain great stability and increased sensitivity.

We can only help you if you show a video, where we see the settings, the swing, and the beach environment.

POOL SALINITY 42.7 PSU / ATS 8 / PULSE DELAY 8µs

3 minutes ago, Willy said:

" 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.

I started a new thread with videos here :

I will post another video tomorrow.
I created a seawater pool at home at 42.7 PSU...

***Please note that the videos are maybe not completely upload***

This is to demonstrate the normal behaviour of the AQ when its coil is swinging under sea water.

Note that the average salinity of sea water around the world (with a few higher or lower exceptions) is between 34 to 36 ppt

Ref: https://en.wikipedia.org/wiki/List_of_bodies_of_water_by_salinity

Here the IMPULSE AQ LIMITED IN SURF PART 1 --> 7us pulse delay

SALINITY 36 grs per liter (PSU)

This is the link to a video taken during such tests.
There was no reaction of the AQ while balancing the coil under the water (50cm deep)
There was a fast recalibration made by the system at coil entering and leaving the water surface

The test have been conducted in the surf of a beach facing the English Channel as a confimation , (Average Salinity = 34-36 ppt)
This is the link to a video taken during such tests.

Here the IMPULSE AQ LIMITED IN SURF PART 2 --> 8us & 9µs pulse delay

SALINITY 36 grs per liter (PSU)

Here bad and good swing difference with 1 inch variation
