Fisher Impulse AQ detector update

[Caribbeanson]

Interesting but 1 meter on the waterproofing?

Not exactly "neck height" for the avg human but either way depth limits scare me. As in, if the depth rating is 10ft I would comfortable pushing it to 6ft, but if the depth rating is 3.2ft I would be wary of anything more than knee high wading.

Obn

I am confused are you saying you need a bigger scoop, or your gonna be detecting in water's over neck- deep howboutit , I figure your good up to nose deep with the Go Pro head mount like a sub's P scope

 

[lytle78]

OBN - Do you dive or snorkel? The 1 meter depth quoted likely relates to the control head. With the control head down a meter, the water would likely be over your head.

It’s not just the discrimination that sets this apart. It is significantly deeper than any beach or diving detector. At the same time it is significantly quieter than the TDI, for example while being significantly deeper on targets large and - more importantly - small.

No dive, best I wait to see some real world users. Maybe then...Thanks again Rick, you really have been the one that should be a spokes person for Fisher on this subject. And I am glad we got to see it is near.

Just thinking, wonder what happens when you need a new battery, say 4 years down the road...something else to consider.

At the price level indicated in the article, it is not an automatic “must buy” item. I’m sure Fisher wishes it could be sold for under $1k. With the kind of premium electronic and mechanical components in this design - combined with the fact that they won’t be built in the tens or hundreds of thousand unit quantities that FT’s mass market machines are built in - means that the “bill of materials” will make it impossible to sell at a more “popular” price point.

2k cat mmmmm the disc on a Pi is about the only thing i see nice with this machine, not the white coil, nor the knob's, my White's Df find's the smallest of target's in the wet, true i dig all , but at 700 clams, i can tell you over 2k, Fisher won't be swimming in cash like ML Equinox sale's, , if they were smart, no more than 1500 clam's , otherwise like OBN and all the other pro's -Watch & See will be in effect. Ps I don't see the waterproof head phone's , to many manufacturer's have developed - just cheap, or mid grade headphone's , no OBN skullies , if the machine is deep, it's about time manufacturer's bring out nothing but the best , high end headphone's , for high end machine's - to here the deepest of target's . Wireless headphone's to boot, Strait shaft- no S Shaft , digital head - no knob's, no white coil, better battery hour's & life -all which should be standard at 0 extra cost , for this machine to be over 2k , not impressed.

The headphones have been selected I heard - I expect you will be pleased with their choice.

The price is - as I pointed out - a result of premium components and a low production rate. This is a niche product. Not like most of their other machines which sell in the many thousands - per month - or even per week. That means low quantity discounts on bought in components. High build cost and amortizing an expensive development process (they acquired the whole European development program and hired the developers) means a high cost per unit - high cost, even at perhaps less than normal margin to keep the price down - means an expensive detector.

It is not for finding lost kids toys and clad change - it is for one thing - gold jewelry.

When one of your hunting buddies gets one, you can see if it is worth it to upgrade from your DFPI. I had one - liked it and found good stuff at Virginia Beach. I have used the AQ - it is WAY deeper and quieter than the DFPI or the TDI (I had two of those).

I meter depth rating for something that doesn't even have a screen? That's not reasonable. I don't dive but I believe the greater the depth rating the better it would handle the conditions we subject it to. That's just cutting it too close. If I'm paying over 2 grand for a supposed "water machine" it should at least cover snorkeling depth.

 

[Surf Master]

Good spokesman

Interesting , let me guess, April the man jump's out of the air plane for the 1st, best ever Pi Disc machine , the King of detector's , i smell the chum, but not biting the hook over 2 k , ill let Dew hit the hook , thank's bro. Ps Felix , i agree at least 3 meter's , as the Equinox, Ctx3030s, - 3 meters, cz21, Excaibur, Whites Df , most all other water machines without a id screen are good to 200 feet All this time for development with short falls , not good.

 

[lytle78]

It’s not designed for snorkeling or diving.

There are lots of considerations in case design including heat dissipation.

Greater depths in salt water introduce new considerations in PI detector operation including the machine “seeing” a much greater volume of seawater. Short pulse delays become unusable and therefore sensitivity to smaller or deeper targets is greatly reduced.

Salt water beach hunting is already a niche - snorkeling and diving are a couple of niches which are even smaller. They are already pretty well covered by the Excalibur and CZ21.

The CTX is rated for 3 meters - how many leaked?

The biggest source of water penetration in IP rated devices is pressure peaks caused by water impact - a wave slams you and the effective PSI on the case is very high - The gradual increase of pressure by descent into greater water depths tends to squeeze things symmetrically and presents less of a challenge.

 

[Surf Master]

I here ya but

Look's like the head is not in a box like the TDI, or Df, it look's like a Euro Tek Pro screwed into a S shaft , not the best designed in my opinion, with knobs to boot, new technology , also should come with a new decade design , not 1990's , coil wire inside a strait shaft, digital head - no knob's, waterproof wireless high end- headphone's , at only 1 meter mmmm, a id screen- ML did it good to 3 meter's, , no white coil with ear's that appear could break under water, ok i will give you credit here, id pay no more than 1500 clam's , and let Dew take the hook his pocket's are blooming out

 

[lytle78]

So don’t buy it. Others will. They will use it and then we will know whether the enthusiasm about the first PI beach detector with usable iron ID will be revolutionary or a yawn.

Eurotek Pro (an amazing value for the money) has a ‘VDI and push pad controls.

This machine is for work. The same ergonomic shaft set up as the F75 - an ergonomic design which is still the best in the business. Knobs because they allow the user to make fine adjustments without having to deal with a front screen which - between bright sunlight, splashed water and perhaps dried salt - is often not easy to read. i know there are lots of them I can’t read without reading glasses and wearing them beach detecting isn’t exactly practical.

The lack of conventional discrimination with numbers or a needle to show where along the conductivity spectrum a target registers isn’t of much use at the beach where the prize is a low conductor item of gold jewelry. Don’t most operators of Excals and CZ’s hunt in all metal or zero disc and cross check - relying on the sound.

As far as the coil connector, a center connection minimizes the torque on the coil mounting points compared to an offset connection (the water drag on the coil is more symmetrically distributed whereas on the offset on the larger drag forces are ahead of the mounting point, introducing considerable torque stress in the coil mount). Also the clevis type connection on the AQ and the curved collar it mates with look considerably stronger to me that the usual ears. Here’s A better picture of the coil connection. The bit of cardboard is just packing material.

I didn't consider heat generation and your're spot on with the rest and water impact.

I don't care for screens in the water. I see too many hunters become enamored of the numbers in the water as they try to read the screens and waste time instead of just digging the sound. Knobs are much more preferable as well to push pads. I really like the look and design of the detector.

OBN - Do you dive or snorkel? The 1 meter depth quoted likely relates to the control head. With the control head down a meter, the water would likely be over your head.

It’s not just the discrimination that sets this apart. It is significantly deeper than any beach or diving detector. At the same time it is significantly quieter than the TDI, for example while being significantly deeper on targets large and - more importantly - small.

Quieter than which TDI? Looks like it can only be bumped up to 11 on the delay... And running under a delay of 10 with that large of a coil. I may buy one just for giggles, but I seriously doubt as a beach machine it will be deeper than my modded TDI Pro what I made my own coil for and running at over 19V... Even doubt it will out depth my TDI beachhunter which I already modded with a different coil, more power and adding two switches...

Reminds me of a cross between a Foster machine and a TDI... I am one of the few on this board that hunts almost exclusively with a pulse. Even with a SAT and how the tuning is labeled, heavy mineralization with moving water, only being able to bump it up to 11...

They put out something, so give them credit for that. Willing to bet that in "discrimination" 24k/pure gold could be missed. If it is using the "reverse tone" then I answered my own question...

Will watch it unfold, I like to keep my mind open. When it is released here give me a holler, couple areas I can use it at and will know in minutes if it is any better... Take care...

 

[lytle78]

Quieter and deeper than either of my TDI’s - the 2nd one had Reg Sniff’s mods. Quieter than your TDI - we will probably never know because it is likely you will never buy an AQ.

It has been tested by LE.JAG against the Beach TDI and he has said the AQ is significantly deeper

At max Iron Mask 24kt rings would be ID’d as a high conductor - you are correct - If you hunt where 24k jewelry is common, you would be careful about using discrimination.

Good point's noted, i see a heavier line , that's good, as ML 's have failed resulting in - buy a new coil line & coil , all one part , as far as less drag , dont know , never saw a coil with the line mounted in front , are coil's going to be interchangable , or hardwired ?, and the last question does it come with a Fisher 5 year warrenty .

 

[lytle78]

the TDI is basically an Eric Foster design - “productionized” by Whites. Alexandre Tartar - the developer of the Manta (now Impulse AQ) studied every Foster design ever built and developed the basic concept of a two changed PI with GB for beach use. Extensive development over nearly a decade resulted in greatly reduced noise and innovative ways of utilizing the information from the two GB channels to optimize for recovery of gold jewelry.

The minimum pulse delay setting runs fine in almost all cases. Carl Moreland - the chief Engineer at Fisher posted a while back that he ran it at under 7 microseconds delay in running salt water at an Oregon beach - likely with significant mineralization.

I had my “mitts” on one before Christmas for a couple of days. I ran it on this beach in San Diego with the minimum pulse delay and the stripes of black sand were a noise problem, so I increased the PD about half way and the problem went away. Set that way I hit a nickel at 17” buried in this stuff.

Dont know how i got brought up but..... you can bet one thing Surf....mine will get used....and I’ve got a plan on just how to use it. How many machines have you seen me buy that didn’t pay for themselves? NONE. There are things I’d change....but there always is. I like the box and even the knob design which I didn’t think i would. Didnt i read the battery is expect to last 10 years. My hopes is after market companies will get into making coils for this puppy.....heres another one for you shaft makers. If we get aftermarket coils..... standard type shafts can be used. Damn skippy....I m in line..... ive always been in on this one from the start. Right now i could see me getting down to the MDT and the Fisher if it does what i suspect it will do. I just wont need the Nox. Looks like thou .... between the Fisher and this machine..... selling off machines is going to be a give away. Pricy..... ya, but anyone full time hunting should know it will pay for its self. Have we forgot the CTX, ATX....and those ML gold machine prices? 1 meter ..... like Carl said once its up to the manufacturer to set limits..... even if the parts are IP69. Ive had a CZ apart .... which is rated to 250'... id bet my paycheck this is to keep you crazies from diving with it lol. Its a wader. Oh that WHITE is a very good color here in the Gulf..... i paint the front of my coils white and have tried several different colors and go back to white.

Tnss thank's for the update, OBN - just what i need to get below the replentishment sand, 1 dime , 6 Felix, 1 piece of encrusted junk yesturday afternoon , if that's a pick of the machine , i am not a fan of the WHITE coil, just like the 15 inch for the F75 Fisher - loose it , happy hunting guy's. Ps Joe - don't worry about the price, if Fisher loose's the White coil i will buy 2 , and hand over one to you for testing howboutit , beside's next trip up North , it's to spank the Ct boy's , they have been bad boy's

you need to find stuff to beat us earl how bout dat

thanks for sharing with us i love the depth of my TDI pro but always worried it was gonna get wet i cant wait to seethe AQ in action i will save up for this machine for sure im interested in it thanks again
