I figured it was time to change the battery for my X--35 9" coil, I watched all the videos on how to do it , I figured it would be a cinch,  but after i got the little plastic plate off the bottom of the coil a hard piece of foam was glued in so hard over the little battery connector I could hardly get it out , then i looked to find the connector  to unplug the old battery  and could not even see it , It was totally covered in epoxy glue I pulled on the wire and it broke off, apparently the temp worker filled it with glue and completely covered the battery plug in making it impossible to remove,  why me ? why does it work for everyone else but when i go to do it  its covered in glue, ? I was pissed now it will cost me 300.00$ to get the HF coil . I will never buy another X-35 because I have no assurance the battery plug will not be glued over again .  at least the HF coil its possible to change the battery

 Post a picture... I owned USdronerepair for years and fixed hundreds of PCB's and electrical wiring issues. I can guide you through the repair.

I am all about freeing up time so that I can get my hands on a 9.5x5" for the Deus 2. The 11x13" has been phenomenal and the 11" is no slouch but I have beds of nails that could use a small coil. 

I dont understand the fear behind tick bites. If you get a tick sucking your blood just pull the dam thing off. I have had the double bulls eye on my abdomen from a itty bitty dear tick, no symptoms besides the rash. If its been on you less than 24 hrs you dont get Lyme disease, and this is from the CDC.

You guys must have some brutally infested woods and get multiple tick bites a trip. I had one on my scrotum as a 14 year old, was there over night during a camping trip, thought it was just tender from needing something. Discovered when I got home and took a shower. My friend told me I had to burn it off and I hung up the phone on him.  Pincher gripped and removed. Horrible discomfort for 3 days.

Do you have a photo of yours? I could "lens" it.  🙂

Here you go. 

The large brass foot is intriguing to me as I found the exact same thing here at an 1850's homesite. Its connected to a brass rod and has a finial in the middle of the 18" section. I have theorized it may belong to an early car.

I hear rumors of a 6” coil. I scored a .65 cal musket ball today along with two pieces of silver. One is a silver salt shaker and the second piece is the bezel to a pocket watch crystal.

I have been looking for the bezel of the monstrous Silver engraved pocket watch I found in the yard 10+ years ago. Unfortunately this is not it. It does however make for the third silver pocket watch or part found in the yard. Another half dozen coins but nothing dated older than 1959.

 I am digging iffy signals that hit one way repeatedly, huge 6” hand forged square nails keep coming up. There may have been a very early structure here before my town was founded in 1857.

Surprisingly no emi problems with all that juice running under foot?

Hardly anything to complain about. There is a 120' foot run to the cabin, 210' run to the workshop and 400'+ to the well pump that I have not detected yet.

The 1860's bottle dump has been dug but not detected with the Deus, I did detect the 1890's up and the Deus did not fair well with the 11" coil, I need a very small coil for this site. The 4x6 on the v3i struggled here in the sheets of rust and nails.

Okay…. The big iron you see in the picture represents a small fraction of the nearly 200 years of accumulation this site has seen. Vast majority of iron was found in the holes with non ferrous targets.

 Much of the nonferrous targets where near one of the 4 buried power lines or directly under the aerial pole to house run. Over 600’ of buried lines in the yard.
 

 If are not seeing the same results than it’s likely you don’t have the same circumstances. I am only sharing because I enjoy the hobby so much and am sure others will benefit with the same environment. I will buy the next flagship detector from whatever manufacturer rivals XP. I have no bias in this.

I spent 4 hours digging today and dug 15 coins. This detector is absurd. 10 minutes ago I dug my first .02 cent 1864. This coin was on my bucket list.... 8" down between tree roots directly under power lines. I am in shock, I want to cry....😅 I have detected this area well over 500 times. Square nails are everywhere.

 I have around 8-10 hrs on the detector now. What a difference this machine has made. Well over 100 non ferrous targets out of the ground including a paper thin brass silver plated cigar tube that was at least +10" down and I am afraid to even say how deep it was because people will not believe it. I also scored a 50 cal rimfire casing, toasted but a nice period relic, 8"+ down. 

 In the coin department I really cleaned it up with the v3i but I have found another 10 coins that keep popping up with iron. Every target except the rimfire cartridge has had masking iron that the v3i could not punch through but the Deus cut through. The sweet rise and lower of high pitch sure makes you know there is a target. If its choppy its not usually good. My soil runs around 87 and this is the first machine that ignores it quite well.

  I sure hope to beat everyone else to the old hunting grounds. There will be nothing left after I am done. For those complaining about the pinpointer taking too long to pair, turn the pinpointer on within a foot of the control box and it is nearly instantaneous.

Just a quick follow up. 2.5hrs yesterday in the hunted out yard got me 4 more coins (pennies), 3 buttons, a ridiculous 7 pull tabs!, and a dozen blobs of lead and melted aluminum.

10%? of the yard covered over the last 2 days....So much more here to find. Most if not all of these targets had multiple nails in the hole with the target.

 Anyone of these targets could have just as easily been a gold coin or ring. The pull tabs are coming out of the ground 6"+.  I am going to find a gold coin!!!!

 The most remarkable thing I have found is that in 40MHZ I can detect right over the top of the buried power lines in the yard and I dont hear any EMI unless I am right over the line and even then I can still hear the targets as well. This is with a lowered gain and depth is most certainly affected but it got me half a dozen of the non ferrous targets. This is nearly a dream come true.

Hi Burlguy,

Do you think that had the coils of your previous detectors gone over the exact spots where you recently made finds with the Deus 2, that you still would have found something? Or is there something special about the Deus 2 that made these new findings only now possible? If so, what might that special thing be for you? 

I absolutely went over all these spots with all of my other coils multiple times. There is some sort of secret sauce going on in the Deus. I did dig several ferrous targets that gave me a choppy signal, bolts, hand forged 2" nuts, and several chrome plated lug nuts. The v3i told me they where ferrous.

The Deus frequency weighting must be one of the secrets of its success. The x y factor of the frequency return response must be determining something additional with the decay. They hint of this in the manual with their graph. It shows bending of the return signal, maybe different time sampling or perhaps its just the weighting of the frequency sampling? 

 One thing that I also liked yesterday, I did not get a single ghost signal that I could not find with the Deus after opening the hole. If it says something is there, its there, not a halo signal being broken up.

I am getting more separation at depth with the larger 11" coil than I did with the 6x8 sef butterfly and v3i.

On shallow targets the two coils are very similar but at depth the 11" has better separation in FMF programs than the v3i running 3 frequency and the 6x8.

 I have not tried any of the single frequencies yet and will give this a spin today.

I do have a complaint that the darn pinpoint volume on the Deus is much too loud and I have not found a way to adjust this and there does not appear to be one.

To be clear here I am talking genuine multifrequency. Not selectable frequency misleadingly labeled as multifrequency, so we are now supposed to say “simultaneous multifrequency” or SMF, to differentiate. Sorry, I’m calling BS on all that. Selectable frequency machines are still running in a single frequency. Just because you can pick the frequency is not new. Been around for decades! When I say multifrequency detector I mean multifrequency detector, a detector comparing two or more frequencies to get a desired result. I don’t need to change my thinking. Marketers need to stop calling selectable frequency machines multifrequency. It’s misleading, I’m not playing along any more, and handing out thumbs down to those that continue to do it. Machines are either single frequency or multifrequency. If you want to your your single frequency detector as being able to select frequencies, fine. But quit calling it multifrequency. Even Minelab never stooped that low, and they had single frequency detectors that allowed you to select frequencies. far before most did.

So what was the promise? Or more accurately, the hype, of multifrequency? It has been that multifrequency detects all targets, large or small, high conductor or low, all at the same time. As opposed to single frequency, where each frequency is strong in one way, but weak in another. To this day I see this said in marketing, and I constantly see users repeating it as some kind of fact.

More BS. As anyone who follows this should know by now, the underlying frequency mix still rules. Minelab calls it “weightings,” where each mix is weighted higher or lower frequency, depending on the desired end result. So we have high frequency weighting for gold prospectors, and low frequency weighting for saltwater, as the most obvious divide.

Mumtifrequency does have an inherent strength over single frequency. Comparing at least two diverse frequencies gives more ground and target information to the system. This, in particular, generally results in better target id capability. There also is a very real ground handling advantage on mineralized saltwater beaches.

But you can’t make multifrequency detector that runs in all frequencies at once, that will do the best on everything everywhere. If so we would not have all these different modes, Park, Field, Beach, and Gold. The end result is not much different than a selectable frequency detector. You have high frequency mixes, or medium, or low. Each serves a purpose. I still have to choose frequency modes, and it hardly matters if I am saying high single frequency for nuggets, or high frequency weighted mix for nuggets. If people were not told different, they would not actually know it is any different, except for the extra target id and ground handling capability.

So stop with the “multifrequency finds all targets across the entire range” nonsense. It’s simply not true. There is no multifrequency detector made that runs in one mode, and hits tiny gold nuggets, while also working perfectly well at the beach. That’s what we are being sold, and it’s simply not true.

 Thats why the v3i was so revolutionary. Using 3 frequencies... you can see the target strength in all 3 frequencies at once using Stereo Mixed mode during real time search, not just pinpoint.

 By selecting either, "best data",  it would alert you of a target in your selected vdi range hitting on one of the 3 frequencies.
 If "correlate" was selected you could set the amount of "span" or difference of target response for the 3 separate frequencies so that it would not identify the target unless it fell into the selected VDI range for all 3 frequencies.

It was an example, but yes my Ace has beaten my Equinox on a deep silver threepence coin in that situation.

Apples to Apples? A cheap little Ace 300 vs an Equinox 800 is never going to be Apples to Apples.  Everything should be in favor of the Equinox.  Putting a slightly bigger coil on the Ace shouldn't be scary to someone so confident in their Equinox abilities 😉

The reason I'm so confident in this is I have a little coin garden setup in my yard, I'd run my Nox over the area so many times and my other detectors at the time too, there are a mixture of coins I'd dug in and old roofing nails from when my roof was replaced years ago.  One day a couple of years ago I fired up my Ace with Tornado 13" coil and was messing around detecting with it checking the targets in my little test garden, it hit a good silver coin target signal notch, I tested the target with my Nox, it ID'd it as junk, so I thought my Ace must be falsing.  It wasn't one of the coins I'd buried.

I decided I'd dig it up knowing my wife will kick my butt for digging up my front yard and out popped a little very deep silver threepence, a fair bit deeper than my Carrots length.

I've since repeated the test by digging a hole elsewhere outside of my yard and putting a threepence as deep as the Nox will detect it reliably and the Ace hits it fine so I went deeper and the Ace continues to ID it when the Equinox losing it.  Yes, the Ace has a 13" coil and the Equinox an 11" in this situation.  In the right ground conditions these cheap entry level type machines are good machines and someone can do really well with them.  The Ace 250 had a massive following years ago in parts of Europe especially Russia I think with their mild soils and the 13" Tornado was the coil of choice for them, which is why I bought the Tornado for mine and I can see why they liked the combination for deep targets.

 I had a friend running a bounty hunter cranked up to near max gain find a half dollar near the 16" mark in an iron infested back yard. Crazy luck does happen and he was never able to have success like this again with that machine.

 I still don't know how the V3 ever made it out the door.

 And some of us will be eternally grateful that we got to have such a detector that still is barely rivaled 14 years later. Why the new detectors dont show multi frequency strengths during pinpointing to allow determining of potential targets leaves me stupefied.
 Silver quarters, dimes and clad quarters and dimes along with copper pennies always hit strongest on 2.5, bottle caps nearly never. When hunting trashy sites with lots of targets this really makes things easier as the iron can break up identification but, "frequency strength + VDI" is a 95% benefit. Damn them smashed crew caps thought.

Using the above scored me a 10" dime last night and every one of my coins for the last 10 years.

As long as one test setup is used and is identical for all detectors a person is testing, then it really does not matter. It is only when people are trading results that consistency is so important. And frankly you’ll not see much of that from what I have observed on the net.

I in fact promise my normal nail test board is not standard. It’s about four feet by four feet, and has an assortment of ferrous stuff plus hot rocks with multiple target setups. Custom made as needed. Montes test is too limited for me, as nails are not really my problem anyway. It’s all the stuff that creates false signals, like flat steel, any hardened steel, washers, etc. plus hot rocks. The only nails that trouble me in the wild tend to be broken square nails or bent nails. Separation matters but I am also testing for a propensity to accurately identify ferrous objects that create false non-ferrous readings. Nobody seems to test for that, but it is a rare detector that will accurately identify a simple round lid from an old steel can. It's not always the detector with the best separation, that's for sure.

A Steve Test Board....

 The right section personifies my hunting conditions except it would need to be in the 3rd dimension as well. After 4 years of not finding a silver coin in the yard I have found 2 in the last week. I attribute this to going extremely slow.
I recovered a burned silver dime 4 days ago running a 6x8 coil on the v3i running a span of 50 in 3 frequency, half a dozen nails in the hole and dime is bubbled and curled like a potato chip. We need 3rd dimensional mapping and harmonic decay sampling😁

That sounds more than just outside the box.

I owned USdronerepair and for 3 years modified DJI drones to not fly away by increasing the gain of the GPS module and remedying the onboard cross talk and EMI. I kind of single handedly transformed the consumer drone industry. 

I have some experience and unfortunately sometimes think too big, detectors are a whole different ballgame and require much more software implementation and this is something I have nearly zero experience with.

Yeah, it’s not like I’d know anything about any of it anyway, so I cede the floor to you. 

No... Thats never my intent or my thought process. You have done way too much for the community and I have contributed very little. I thought it was open mic...

But I do like to think outside the box and this has done very well for me.

Yeah, why not just “cancel” that EMI? Easy, right?

Every EMI signal mimics a portion of the target response spectrum, and eliminating it eliminates the responses from certain targets also. It’s possible to isolate an EMI response on a single target id number, or range of numbers, and simply notch them out. But then you lose those targets. Or you can reduce general sensitivity, but now you lose depth across the board - notching may be preferable in many cases.

There is no methodology for reducing or eliminating EMI that does not come at some kind of cost in the form of lost depth or targets when running SMF detectors. The best bet whenever possible is to be operating on a frequency or frequencies totally outside of whatever is causing the interference, even to the point of using a different detector, if need be. I’ve found 19 kHz single frequency units to be among the most trouble free detectors I’ve used, when it comes to common EMI issues in U.S. urban locations.

I tend to prefer detectors that go nuts when encountering EMI. At least I know about it, and can maybe do something about it. Some older units, in particular, suffered from “silent EMI,” where you simply lost depth or targets in the presence of EMI but had no idea it was happening. The Fisher CZ machines are kind of famous for this issue.

 

With todays speed of processors there is certainly a way of removing a vast majority of the unwanted air signals that mimic wanted signals/targets.

Most of the time when experiencing EMI, target signals will still show up stronger than the unwanted EMI. Obviously there will be the impossible situations, buried dog fences, high voltage eddy currents, etc.  But so much of the chatter can be eliminated with some focused engineering. 

 Taking a constant environmental sample away from the transmit and receive signal could go a long way in reducing this. Offsetting frequency is not nearly enough for most situations. I am sure its being worked on, in fact I know its being worked on.

Subtraction of data from white gaussian noise is how are cutting edge long distance radar is now identifying threats. We may see something similar where EMI is no longer a problem but a way of helping define targets. Sufficient processing power will be needed, perhaps we will see quantum detectors?

 

Why the heck there is not an EMI receive coil built into the controller to cancel out EMI leaves my mind boggled. Sure the detector may lose some depth or targets occasionally but it would silence most of this flute insanity.

Why do you not just use a PI Burlguy? You're basically digging every iron signal anyway, you may as well have the superior depth the PI will give you and not even bother with another VLF.

I tried this with a Whites Beach PI DF. I was able to move a couple inches at a time between targets.  I am dealing with 3 generations of burned structures along with the the 1980's disaster of tenants digging holes and burying  household trash. I have been contemplating building a shaker screen table and excavating 100sq feet at a time. I know there is gold coins here.

I live on a 1860 homestead that was a railroad tie makers camp, a military camp, a civil war soldiers home, a stage coach stop and had the local most prominent family of the day living on it. Much of the land is covered in nails and I have dedicated myself to removing everything from the ground. 2 silver pocket watches, countless brass pocket watches, 4 gold rings, 100's of wheats, countless scraps of silver but only 6 silver coins. 500+ clad coins....But.

I have "soil" but its so filled with minerals and rust that some areas I can only see a clad dime at 2" other areas I can see a wheat at 7"+. I found a bowie knife at 12" last night in the packed gravel driveway. The pay layer of old coins is somewhere down there. Every time I have had to do any ditching to bury a power line or water line I bring up old coins, 3 coins from 12"+ deep the last 30' ditch I did. I have resorted to trying to dig every large nail and iron and I am literally at about 100lbs of nails and iron this month over this 2 acre area.

 I have been running the Whites v3i for 12 years, and run every coil 4x6" through the 18x15" and use every frequency to squeak any signal I can 

I am hoping that the DEUS 2 might help but there may just be no magic bullet for ground like this.
