I have been following the pulse induction developments at Fisher Labs since January 2015. Things heated up in January 2018 with the Manta prototype that later became the Impulse AQ. I followed and posted every tidbit I could find about this detector from 2018 on, with much of it coming from Rick Kempf.
Why my interest? Simple. I have a history of some pretty serious PI beach detecting. I've used every ground balancing beach detector made... though that's not saying much since there have only been a few. It has been my perception that this is still one of the most under-served, undeveloped portions of the metal detector industry and technology remaining to be exploited. Manufacturers have produced few waterproof detectors compared to other models, and really only the VLF multifrequency models have kept close to performing like dry land detectors. Ground balancing PI beach detectors have fallen far behind the technology available to gold prospectors for dry land use. The new Fisher model gained my interest not only due to the new potential performance benchmarks promised, but the ergonomic design, which looks to be far better than any other similar options.
Fisher Impulse AQ Limited
Anyone with any sense should know I've been trying to be first in line to get one of these. However, I have not attempted to get in extra early by being a beta tester. Frankly it is a lot of work and not worth it to me these days, even for a free detector. So my goal has been to get my hands on the first one I could purchase.
People who have been following the Impulse saga knows it has been a long, strange trail. The long story short is we are all aware of pictures and specs of a version of the machine that Fisher currently has in hand. The most recent photo is above. However, they have decided it needs more work. In particular, longer life batteries, and a redesigned battery system overall that eliminates some weaknesses that currently affect the waterproof rating and possibly the durability of the detector if mishandled.
Rather than put this off for more months and probably next year... honestly who knows, given how things have drug out... Fisher has decided to take the hardware they have on hand and produce a short run version of the Fisher Impulse AQ - the Fisher Impulse AQ Limited. The word is there will be no more than 100 of these made. In the meantime work will continue on a future release that addresses the items I mentioned above.
The limited production run is intended to target experienced beach hunters who A. know and acknowledge the limitations that exist in the current model and basically promise not to be complaining about what they have been told up front they were getting in that respect and B. people who will be able to offer good, solid, genuine, reliable reports about the detector and what it is capable of. Not sugar coaters, but people who can offer constructive feedback that can be incorporated into the ongoing development of the detector. So kind of like paying beta testers, but not exactly. I'll leave it to the copy of the Fisher disclosure statement I am posting for you to review and which explains the details to decide what it all means for yourself.
So why would you want a model that has a limited depth rating and short life battery? Killer price my friends, killer price. I have no idea what the final version of the detector will cost, but this one will be available for $1499.
To me even more important is the ability to hit the beach before anyone else with a machine that few will be able to get for some time. I am a "who knows what the future will bring, life is short" kind of guy. I'm going to grab one of these now while the grabbing is good.
Due to the limited supply and desire to get these into the hands of a certain group of people, Rick Kempf is the acting "traffic cop" for this limited release. Basically as I understand the process people need to contact him and make the case for why they should get one of these. He will no doubt chime in and offer more details on how to go about that. These things are being built in small batches so it may take a little time to get one.
What's my part in this? Well, not much. I have agreed to the terms and sent a check and have a detector coming soonish, whatever that means. I plan on some fresh water lake detecting and even a little nugget detecting, and will post my thoughts when I have any serious thoughts to post. I did not sign up to promote or do anything at all really except go metal detecting. I'm paying the same price anybody will pay and the terms to me are the same as you read below.
Frankly I feel weird posting this, but I asked three separate times and confirmed I can post a copy of this and that the price of $1499 is correct. I must emphasize that I am not a representative for Fisher and am not making a dime off any of this. I'm only passing on what I've been told so far and can only vouch that it is what I have been told. Since I’ve never held the detector I have no more idea than anyone how it will perform other than to say it is a pulse induction detector, and don’t expect it to act like a VLF, especially as regards discrimination. You have issues... don't come looking for me! I'm just a guy who has got my hands on this info and I have been cleared to show it to you. If in doubt, sit it out. That's it. I will post more information when I know it, and photos of my detector when I get it.

This was my 3rd and last hunt. I went out for a low tide hunt and I was the only one at the beach. I think it’s mostly because people are going at night and leaving when the sun goes up.
Things were looking good, I was pulling the correct targets that should lead to some gold. Within 1.5 hrs I had pulled the 5 rings and ear ring. I continued hunting but the next half hour I wasn’t getting any targets anymore so I decided to throw a nickel on the ground. I was running all metal and max sensitivity. I ran the coil about an inch from the nickel and I could hear it but not that strong. I decided to start raising the coil and kept swinging until I couldn’t hear it anymore. At about 8-9 inches I couldn’t hear the nickel anymore. The battery was still good but I decided to try my backup that was fully charged. I got the same results on the wet and dry with the fully charged battery. I have no idea what happened with the AQ after only 3 hunts but I did noticed the back of the control pod was rather warm. I don’t know if it was warm because this is a high powered detector or some other reason.
P I shot an email to Rick which he forwarded to Fisher and I got a call back within two hours. I spoke to Felix and he sent me a shipping label so the detector is heading back to FT. I am bummed that this happened specially when I was on a roll but sh*t happens. I hope they are able to figured out what happened quickly so that I can get back to swinging and learning it some more. Good luck out there, HH. The 3 rings and ear ring are silver. The other two rings, one is tungsten and the other is junk. When I was about to dig the junk ring in my head I was like this is a big ring, pulled it out and I’m like 🤯 The pictures show all the targets I dug this hunt.

Above being said.................. the one problem I have with the "AQ" it's audio blasts when I move the detector to the side to dig and there is another shallow target under/near the coil........ I mean it is loud, and since I use the head phones I make (skullies) which the DB rating (sound level) is 15 plus over anything out there..............I get blasted if the "AQ" comes near the scoop, moving it a side to dig.... hitting another target..Or the AQ going back into the water......Not complaining, just one of my things that I've not seen anyone else talk of.... that I can fix..while I am making a battery for it.
IP68, Bulgin On/Off...
Joe, are you using a bms module inside the 4s1p tube?I hope not because....
I actually don't know if I'm correct but seems to be the easier combination for a self balanced recharge without the need of multiple solder and little cables around cells, not to mention the module itself presence inside the pod...
I'm developing a similar pack for the Tdi and can be the base for the future of my dreamed AQ...
So I wanted to go back to my favorite beach since this time I would hit it at low tide. Not a great low tide, but enough to expose a good stretch of wet sand where I am dying to try the Tone (and Mute) modes where there is a decent amount of iron present. Today was not that day. Completely sanded in so I will have to wait until this beach gets ripped up a bit. It does not help that they groom the beach every morning. Last time the grooming guy came out of his way to circle me, trying to intimidate me into leaving I heard almost no iron, so I knew it was deeply hidden. 2 1/2 hours flies by and I'll probably have to wait until my good season hits this fall. I guess I'll have to cough up some cash and buy that Xtreme scoop so I can maybe hit some lakes with it. I'm not strong enough to handle those rough waves at these exposed beaches like you veteran water guys are The surfing dudes will be scraping me up out of the water. I'm not disappointed in the machine, just in the beach conditions and of course the short time allowable to hunt.
