Fisher Impulse AQ detector update

LOL Craig .....im hoping thats not the case. I tell you one beach i hunt thou could get bad...... WWII casings and bullet pieces. TINY... bullet pieces. As a water guy here in Fl..... i just dont see how anyone can go wrong having one of these in their closet. There are times with so few targets its worth having a deeper machine.... disc or not. If this rivals Eric Fosters machines...... this should be fun to play with. If it doesnt work out...... ill have to sell it BEFORE word get out.:laughing: Ill be keeping quiet for awhile on this one. Maybe a learning process for me. Man..... i get the coil coverage...... but i H O P E... they make a 9" coil. Otherwise could get tricky with multi targets because of the size and HALO on this coil. Its not a VLF so i dont know what its going to do with near targets. Carl said Dec early last year....... then Feb just last month.......her we are Feb and we arent getting any marking. Seems like OVERSEAS market is holding us up here. I say let them have it when or IF they ever get their certification.:lol: Yes its all about ME......hey i got a great idea send that upgraded one Ricks getting to me.:laughing: Id dont know anymore about a PI than he does..... but i do know how to get it wet and test how sturdy it is.

I believe that is going to be the secret to the "AQ", knowing when and where to use it. If they do come out with a smaller coil that will allow it to be used in more area's. The 12.5 coil size is really going to limit the machine to wetsand and out deep hunting where there are less targets. Infact I don't see it doing well in area's with a high concentrate of targets. Not even with the smaller coil.......
 
I dont know Joe..... a small mono does pretty well. The one on the Finny i liked much better than the bigger DF. PPing with this big of a mono coil and the coil HALO could make for some big holes on some little stuff. Im wondering the depth you might loose as you raise the delay to certain targets in AM mode? In disc mode ..... thats going to be the tell if this machine will out class the others we already use. I have no doubt it will in AM.... but if you switch to disc and you get NADA over the target.... even a weak one most will walk right over it.... but WHAT IF. Will we have to change our thinking .... start taking a little sand off every target? Thats ok..... provided we can get that big o coil sideways or something to get in the hole.

I know how a pulse works Joe :lol: While you were cherry picking with your Excal I was finding everything I wanted and didn't want... the good old days at FindMall we had some interesting conversations wouldn't you agree :lol:

With these big coils if you have trouble finding target try inverting the coil on its side.. that worked for me with the DF..

I remember a hunt years ago with a guy new to pulse hunting who was a excal guy who was having trouble recovering a target he gave up on the crater he dug so I went in with my DF and in 1 scoop had the target.. it was in the side wall... I inverted my coil ... never told the guy :lol:

I can't wait to watch you show us the mangled AQ :lol:

I started beach hunting with a pulse Dew... just by paying around with the ground balance it would disc out targets I didn't want to dig... I'm at a point now where I don't care if they were offering it for a thousand dollars I still wouldn't be interested in it... 30 years of abusing my body doing landscaping has taken its toll... Plus where I hunt these days I don't need anymore depth than I am getting with the OBN blue... 99% of my spots have a clay or prat base targets don't get past it...

I know all about bullets I have quite a collection of 22 up to 50 caliber Last week hunting with the TDI I was finding them way too deep for my liking..


The only beach I would have liked to try the AQ on that beach...

Who is Rick? :?:

Any idea on the age of the bullets? Finding gold deeper or same level?

Joe I only use pi machines... and I hunt in some of the busiest lanes in Asia. Being able to use it will depend on what type of response and threshold it has. A TDI might have similar depth to an atx but the atx is like a video game sound where as the TDI you have to use your ears, eyes and brain. The only targets that throw me off are small chunks of red brick and deep iron. The iron I could skip but there are big bangles occasionally that I don't want to miss

Some are modern but I have found musketballs and 3 ringers at this spot.. My friend Mark pulled a Rev War USA button from this spot with the wood backing still in place... he found it with his TDI PRO and it was super deep..

Most gold there I have found there was with a PI as it sits at depths out of the reach of VLF detectors... a lot of the gold here is from the 1800's

Put it to you this way... I would be wasting my time using my Excal at this spot...

OBN, ... usually with a coil of more than 11 "it is very difficult to achieve a delay of 10 μS or less ms ...
for a 12.5 "coil, if it is not made using any new technology, the delay will be 12 μS ... in my convex sea eye : D
 
I agree on the coil. Up to now hand made custom coils probably made with the precision of a "swiss watch" could achieve that performance. Once the coil was made than the electronics were probably fine tuned to that specific coil.

Tough to do in a production environment. Sounds like the Nautilus history.
 
So.....are we thinking this machine has the ability to adjust to 7uS...... BUT its going to be very unlikely ANYONE will be able to us 7uS in the salt water except shallow? Because i use a MDT with a salt balance i can tell you things start to change about knee deep...... and deep the chatter starts and you have to adjust the salt setting..... or in this case the uS. Larger coils also tend to require less sensitivity. At this point i dont know if we are ever going to find out if Fisher never markets it will we?
 
The issue with shorter pulse delays is not ONLY related to the design and fabrication of the coil.

In correspondence I had with Alexandre and LE.JAG a month or so ago regarding the minimum usable pulse delay in seawater Alexandre emailed me this:


“It depends a lot on the electronic design and its stability. The coil design also has a huge influence.

I have reduced noise by 90% with a new electronic system and I have reduced variations due to seawater conductivity.

A variation in conductivity due to salt at 15µs of pulse delay on a FOSTER designed is equivalent to a variation at 8 µs on the IMPULSE AQ in term of stability and salt conductivity compensation.”

LE.JAG Added:

“ Yes I confirm
with a short pulse delay, AQ is infinitely more stable than Aquastar
it compensates for mineralization / more easily-

and if you still have a problem at 2 feet, you just have to activate rejection mode (mute or multitone) and set the reject control at zero discrimination. Even at that zero setting it already compensates for salt and mineral more than all metal mode -
and the setting range is very long - you can vary the minimum pulse delay as well as sensitivity and ATS (auto tune speed).”

Of course, all this will be explored in detail by early buyers of the AQ when they take it to the beach and try it under their own use conditions.

I really wish Sandcrab would post on this thread... He is a beach hunter and he knows his stuff...
 
7000 is a serious gold machine..... don’t know if it’s a fair comparison....or at this point any one can answer that.... no machines.
 
I only care about performance comparison on wet sand on a salt water beach like the Florida Treasure coast, can't go in the water anyway.

I feel for you guys down there, totally unfair. Be nice if you had a good blow out tide...

OBN,

GPZ coils are waterproof to only 3 feet and control pod is only water resistant.

Thank you, very nice machine. I think my friend Keith has one..I may need to borrow it...:no:

Forget that...8 grand a little to much for my budget if I got it to wet...and killed it..
 
It's all relevant

Isn't it?
