Whites Spectra V3/V3i Coil Problems - Progress Reports And Experiences

This is getting to be a real problem with the Vision/V3/V3i detector. All this time on the market and the stock D2 coil is still a piece of junk. White's is charging for upgrades to a detector that has serious coil problems. I have had 2 bad D2 coils in the past and finally Whites was kind enough to send me a V rated Super12 the last time in. Early this Spring I purchased another D2 coil and have had really great hunts with it and have grown to like it tremendously. It has become my coil of choice, just edging out the 1:blackeye:12 SEF for accurate frequency response. Today I went out to the local park by my house to relax and had not been hunting more than 30 minutes when I started getting instability showing up. I looked around to see if there might be an EMI source causing the problems. Sometimes generators used by city workers will do this. I finally did the Whites approved test for checking the D2 coil, RX up to 15 and TX Boost turned on. Bingo it overloaded all over the place. As a matter of fact I could not get the RX above 9. I had 2 more V rated coils with me in the car. I switched out to the 950 and tested and then the Super12 both were solid as a rock. So, here I sit with my 3rd bad D2 coil. I will send it in tomorrow. This is sure not the quality control I have been used to in the past with my DFX and MXT. I don't think I will be spending any money on getting the V3 updated. Paying to be a guinea pig is not my idea of good customer service.


So, here is my open and direct question to Whites. Is the D2 coil issue resolved at this point, or do you continue to sell new Spectra V3i detectors with the same manufacture of coil that has this great potential to fail? Are the new individual D2 coils for sale on dealers shelves good ones, or do they have the same potential to fail as my new coil did? If the issue is not resolved, how can you still choose to sell a product that has such great potential to fail in good conscience?

I would really like an answer to this.

Thanks,
Jack

Jack, is this an air test or a ground test? I knew mine was bad when it was overloading on canslaw and falsing constantly. I didn't know of this test, but a coil shouldn't overload on canslaw IMO. On another, I was using the recommended RX test of 7 or less in the air (at one time, I believe White's said this was a valid test, now they are saying they removed recommended RX from the upgrade because people were using it to test the D2, so I dunno).

BTW, have you tried the 6x10. Everyone is telling me to scrap the D2 and just get that, but I'm not made of money, and didn't think it was right to have to buy a coil to get around the bad D2 issues. But now that I will be getting more story money for my half dime story, I just might try that. Or, I might just stick with the E-trac; I don't think it has ever overloaded.

I did not use the old recommended RX as a test. This was an air test with the procedure I saw documented on Whites forum. I don't buy into the hoopla on the 6x10 getting as deep as the D2. A 6 inch dd coil verses 10 inch dd coil. The physical properties just don't add up. I have a V-rated 6X10 and it is not even close in comparison in my tests. I will go back to the 1:blackeye:12 SEF before I use the 6X10 on a regular basis. The E-Trac is sounding better every day... lol

How would you test the D2 on a DFX to see if its bad ?
I'm having serious falsing problems with my D2 also.
I love this coil. For a 10 inch coil the seperation and pinpointing is pretty remarkable :yes:
The stock coil and my 6x10 seeem to be fine.

Jack, As far as I know the test that Whites recommends is to be done without the TX Boost being on: http://www.findmall.com/read.php?66,...02#msg-1161702

The test changed a few weeks back - it's now hold at waist level with Rx at 15 but with Tx Boost OFF.

Wow, I thought that had been resolved a long time ago. :dontknow:

I'm going to kiss my Pro coil when I get home. :yes: :smitten:

lol lol lol

this is part of the reason i don't want to invest in a v3i , the standard coil issues . i was hoping it would of been resolved by now .

Thanks for the post Cyber. I wanted a V3i really bad and almost pulled the trigger. But I don't think I could use one without worrying the whole time. I opted for an Etrac which I should receive today. I wanted a V3i but will be happy with the Minelab. Are you listening White's?

It would appear that The test should be done with the TX boost off. The test has changed again. I guess this is one way to keep the repair cost down. Well this just really makes me sad. I noticed noise issues and instability before even doing a test of any kind. The coil is way more susceptible ti EMI now and I definitely have to turn down sensitivity a lot. I know the exact swing when things went to crap. I was out in the middle of the park. This a large quiet park and I can easily push the V3 out to an RX of 12 and a DS of 95. After the Null Shifted (This is the terminology being used by Whites now) I had to back things down to an RX of 8 to get my DS at 95. I used to be able to air test in my house with the RX at 3 or 4 and the DS at 92. I can't do it at all now. Bummer This is definitely not the same coil that I have been hunting with the last 6 months.

I guess I have a good coil however, because I can set the RX to 15 at waist high with no overload. Just to let everyone know My 1:blackeye:12 SEF coil now runs with a higher RX with and without the TX Boost. Man am I depressed.

I am going to pursue this. I will let you all know how it goes.

Jack

***UPDATE***

I just spoke with a technician at Whites Factory in Oregon. I am not going to reveal his name at this time as I do not want to put him on the spot. I explained to him what happened and asked what if any test I could do to Check the coil myself before sending it in for their diagnostic work. He replied....

Hold the coil in the air and turn the RX to 15. Then turn the TX Boost ON If it overloads you have a bad coil.

I repeated this back and then again asked, If for sure the TX Boost should be turned ON when performing this test.

He replied Yes turn ON the TX Boost.

I told him I was getting overload and he said send it in. So, I don't know what the policy is? The post from the Whites forum seem pretty clear about it being OFF, but the Tech said &quot:daydream:N.

Stay tuned...

My 10D2 can't even pass the Rx = 15 airtest with the boost off.

That is the biggest piece of junk White's ever distributed.

Mine is so bad that it won't run on an MXT with the Gain set anywhere above 3.

It's my second one and I'm gonna turn it in to Sweet Home when I send my V in for the V3i mod this fall.

I queried this with the UK factory a few weeks ago when my 6x10 went just the way you describe. The Tech there said he had been instructed by the US factory to test with Tx OFF. I asked for confirmation and was referred to Carl @ Whites (you all know who he is, I am sure). He emailed me personally and confirmed the Tx should be off. There is a Factory Sticky on another forum that confirms this is the case. I guess not everyone is on message yet. I'd email Carl PERSONALLY if I were you .........

I had coil issues (see other post) but also use the 10x12 and 12x15 SEFs and I also find them very good on the V3i. Today I was running a modified C&J program with Rx at 11 or 12 and Sens at 90/65. It ran perfectly in 3-freqs Salt mode and was finding lots of little bits including a 13thC hammered silver penny.

I have my 1:blackeye:12 SEF on my V3 right now. I have to admit I really love this little coil. Sounds like they are doing the job for you!

I have had the same problem with my D2 coil. I have mine sent in now and I am waiting for its return. crying01 This will be my 5th coil!
Although I am very upset about this coil issue because when it works, it works great, I have an arsenal of other coils to choose from. I feel that this is a big problem with Whites that I am sure they are working on...as I was told.

I do not have the upgrade and I will not be getting it because they took too much stuff out like transfer of programs and suggested rx gain. >:\ Then, they did change the way the D2 coil is tested from rx at 15 with boost on to just rx 15. I understand that overseas is done this way also. I have had D2 coils last from 6 months to one that lasted 3 days.

Although I am frustrated with this issue, I am not prepared to throw out the V3 just because of one coil that they cant get right. The machine itself is a great machine and works great with my other coils. Last night I was out and was pulling wheats at 12 to 14 inches. I was using the 10x12 sef butterfly and my rx was 10 and disc at 85. The D2 could do this very easy and with better ID on the object but I have learned to adapt and overcome the D2 issue. I am already digging holes that I really dont want to dig because of the depth of this machine... Getting rid of the machine because of one coil that will not work is like getting rid of a nice car because the stereo keeps messing up... Just replace the stereo until there is a fix for the stock one.
At least Whites will keep replacing the coil without having to buy another. How many other company's will do that? :thinkingabout:
I thought this was suppose to be an info forum to talk about Whites and how to help each other and work on things together. I have seen nothing on here that is anything like that. I go to other forums to get info and discuss things because that is what they do there. Not in this one. Jack, it sounds like you have been wanting an etrack for a while now. Maybe its best that you get one and stop bashing whites for one bad coil that they have that they are working on... How is this helping anyone on this forum? Especially being a moderator? I feel that this site will just turn onto a minelab dominate site and thats too bad because there are alot of great detectors out there that are just right for certain people. I have never bashed any detector and never will....
Just my thoughts...

I don't understand that analogy. A car doesn't need a stereo in order for it to be functional. Not so with a detector and coil.

No one has bashed anything on this thread or this forum, or we would have pulled the plug on it by now. However, this last post from you is getting close.

People are allowed to express their opinions respectfully. Insulting people is not allowed. You are free to go to those other forums magic, if you are not happy with the info you are getting here.

Hey Magic, I understand your frustration, but this is an open forum for posting what you learned and what you don't like about your machine. Right now a lot of people are having issues with White's coils. It may seem like bashing to you, but If I were considering buying a new detector, I would be greatful that I learned of the problems before I dished out $1500.00. That goes for any detector including the E Trac. The reason you don't see any bad talk on that other forum is because it gets pulled in a heart beat. I'm sure some people were banned because it was not good talk for their sponcers. An honest forum is one that praises when done well, and complains when it's not right. I hated my E Trac when I first got it and was really mad that it came out before White's Vision did. I wanted A White's but couldn't come up with another $1500.00. Now I thank God that I didn't get the Vision. I probably would have borrowed the cash and bought one if it wasn't for these types of posts. Remember it just can't be CyberSage, Lowjiber and Yazoo putting their programs and thoughts on this forum. We need total participation from all V3 users. So maybe if more people posted their experiences we would have that type of forum. But those 3 guys have done a great deal in getting people started with their V3's. I think they deserve some credit too. Just my two cents. :confused: :clapping:

Magic,

I fully respect your point of view. I am glad you feel that you have the freedom here on this forum to voice your thoughts. That's what this forum is about. Most other forums do not have this level of tolerance. Your post will stand, as will mine. I am a realist when it comes to detecting. I am after old coins and relaxation. While I am a long time loyal Whites user, I would not hesitate to purchase a Minelab detector. I am not that narrow minded. I still have my DFX and I will never part with my Vision. I wish I still had my MXT, that was a mistake to sell that detector. By reading your post I can tell you are very balanced, objective, and fair in your observations. We need people like you to participate here. Your knowledge and experience is welcomed. I am not sure why you felt the need to call me out, but I have no problem defending my views and thoughts I share here. Thanks for participating Magic, I like you. Your a lot like me. lol

Jack

***UPDATE***

I sent my coil off Friday and it should arrive by Monday. I sent it directly to the Tech I spoke with on the phone.

Back on topic... 5 bad coils is astounding! Were all the failures the same in nature? What did you first notice behaviorally that tipped you off that you had a bad coil. Do the failure times seem to be about the same?

The V3 doesn't need to use the D2 to be functional either, there are alot of other coils. You can even buy a V3 with another coil instead of the D2 if you so choose.

Epi, As far as me getting close to bashing .....:huh:thinkingabout: like I said, I dont bash any detector. Tell me how I am getting close to that?
I do believe I am in the the Whites section of this forum. I am a Whites man and like to learn, good or bad about Whites.
I have no interest in Minelab and talking about minelab in a Whites forum shouldn't happen, Especially switching to one. I dont go to the Minelab section and talk about how my Whites is better or try to tell people to get a V3... so it shouldnt happen here.
I have been on numerous metal detecting forums and some make it and some dont. The ones that do welcome all detectorist and dont put up with people bashing other peoples detectors.

I am not narrow minded but I wouldnt use any other detector other than the v3. I wanted a detector that can do it all if learned properly and this one is it. I have used garrett, fisher, and minelab. I made my choice by what I liked and I didnt go by what other people said because thats their opinion and not mine.

I agree that participation is needed in this Whites forum. Yazoo has contributed alot to this forum but Yazoo (Mike) is my friend and I talk with him daily. Who do you think came up with alot of the programing? I tried to start a tips section in this forum for users but deleted it after some stupid remarks. I am doing some testing for Whites so I do know a little something about the machine. I think this is more of a friends type forum and not so much a true metal detecting forum. I defended Angel when a guy started bashing him and now I get jumped on for trying to defend Whites and the V3.
Too much drama for me... so just read this and delete my account.

Jack,
To answer your question, All the failures was the same... Rx gain dropped and it started acting erratic. It got to where it wouldnt even pick up a dime at 5 inches. I had one that lasted 6 months, two that lasted about 2 months, one for 3 days and the last one was a month. I do know that they are building them different now and I am testing the new build when I get it.
The main thing that seams to trash the coils is heat and strong vibrations like if you were to drop it. The D2 is a great coil and IS my favorite but its problem is that it is just not rugged enough.

Cybersage and Magic,

As a a V3 owner I too am rattled by all the posted problems with the V3. To be honest I respect both of your opinions and experiences, as I incorporate your shared info into my V3 experience. I understand both of your frustrations/praises with the ever evolving Vision/ Spectra V3 and now Spectra V3i roller coaster ownership ride. Thanks for keeping it civil and please keep posting info on what and should become a great detector. To be truthful I'd love to here more of what is good rather than bad with the White's product but the V3 is still evolving and obviously is having some growing pains we still need to hear about. Please stick with this forum and post more if at all possible.

Greatly appreciated,
xzlr8n

Magic, you misunderstood Epi-hunter's point. She isn't accusing you of bashing a detector or detector company, but she has concerns with your words drifting away from what should be a discussion, albeit infused with expressions of frustration, to that of a personal affront. Also, we do take exception with what you stated about this forum, its not being geared toward helping each other to learn and work through problems we may be experiencing with our machines, whichever machine they may be. If you really believe what you stated, then you haven't been paying attention. You now further suggest that this is not a true metal detecting forum, and that we don't discuss metal detecting related issues, nor that we provide information helpful to our members. Isn't that a form of bashing? Again, I submit that you have not been paying attention.

This forum is fairly young, having a relatively small membership, yet, despite that, the members here have proven to be helpful, informed, and willing to assist others. You really can't do such without being an active member, wouldn't you agree? A forum is what the members make of it. You can have a forum comprised of 10,000 registered members, but if no one, or only a select few, participate, of what use is it? Yes, this is a forum where we all can make long-lasting friendships, that is my hope, but it also offers much in the way of accumulated knowledge and years of experience. I know that I have personally benefited from posts members have made here.

As to what prompted you to make your initial expression, this forum is not geared toward fanboyism of any one metal detector or metal detecting company. If a member brings up a point about another detector brand during a discussion being shared in the White's board, I expect he or she will not be ostracized for such, as if bringing up such a point were some sort of sin. That would apply to any of the metal detector specific boards we have here. As long as it is to make a point, is within topic, and relevant to the discussion, why should it be a problem? Only individuals fiercely loyal to a particular machine or company would object. In such cases, quite frankly, I would prefer such an individual refrain from being an active participant here. This is not a Minelab or White's or Garrett's forum. It is a metal detecting forum.

I do hope you will reconsider your request to have your account deleted. I do believe that you have much to offer to members who own or are looking to own a V3 or V3i. Your input in the white's board would be very much welcomed and valued. I also hope that you won't view our expressions as some sort of attack on you. They aren't. They are intended to clarify intents, and to express concerns about statements we felt were heading in the wrong direction.

Respectfully,

Angel

Let me be more clear. A detector needs a functional coil to work. The analogy of stereo-to-car vs coil-to-detector is not appropriate. You misunderstood my point by miles. Why am I not surprised?

I let this point go from your earlier thread, but it's really what bothered me most. Did you not see the nine page, 200+ post thread on the V3 started by Lowjiber and maintained by him and CyberSage and Yazoo and many others? And you are telling me that this forum does not have info to help each other out and work on things together? And you don't have a chance to discuss things? Where are you on the White's forum? Because I haven't seen much discussion and helping others from you.

As Jack and George and Angel graciously stated, you are welcome here, if you choose to actually participate. If not, feel free to go over to the other forum where such posts are removed because of the sponsors. There, you won't have to be offended by honesty.

If you continue to bash this forum, I'll be the first in line to remove your account.

I hope you choose to lose your narrow-minded attitude, and contribute to the forum instead of criticizing it.

Thanks for your reply's xzlr8n and angel. I understand what you are trying to say. I wish I could get my feelings out by typing like you guys do. Like I said in my original post months ago...no one wants to read through a 9 page post for info. It needs to be broken down into categories like on other forums. I was ignored.. The info here is little more than how to use correlate which is what alot of people are following and is not the best choice for depth or getting to the old stuff. It has been proven and isnt logical.
Epi-hunter.... People go out of this world and live through it with basically only one thing. How they are inside. You sound like a very angry troubled person... May you be the first to delete me so that you may get some satisfaction for the day!
Please delete my account!

Your account will remain.

Have a nice day, magic. We wish you well.

:shocked04: wow i go on a camping weekend and i miss in all the fun. :dontknow:

hey Magic . like you i use whites machines and have a loyalty to them as they have built quality products in the past . have they had some problems with some models or coils or other parts , sure just like other detector makers as well they all do at some point. i think Whites is a great company and can stand a little constructive criticism from time to time isn't that what they get when someone tests one of there products in the field :huh: open honest dicussion is what they want from field testers , yes:huh: why should this place be different then . i really respect the views and ideas you share on here Magic and you have lots to offer .i hope you'll reconsider your stance about forum , as far as Angie goes she is a very warm and generous person that is very passionate about the forum and its people she has come to know and she makes no effort to hide that fact , its one of the things i really appreciate and love about her.

Awww... man, now I am just getting all teared up. crying01 I love you guys. I hate my D2 coil, but, I love you guys. lol

***UPDATE***

When it rains, it pours...

I strapped on my V Rated Super12 coil and went to relax for awhile Sunday and hunt another park in my area. Things started out good and then the V3 got noisy and the stability dropped. I had to adjust way down to get it back. My guts wrenched as I did the RX at 15 test. You guessed it, overload. as a matter of fact I had to drop down to 7 before it would work. This is with the TX Boost turned on. This coil tested out OK when the D2 failed just a few days ago. I switched to my V-rated 950 coil and it tested out great. I returned to the big quiet park where the D2 failed and performed the same tests again. This is a bummer. I think I will be sending the whole mess in to Whites. I will get the upgrade and let them deal with the coil at the same time. Man this is not my week. I am looking forward to some quality time with the DFX and Bigfoot coil. Time to rake some Quarters and dig pull tabs.

Keep Swing'in
Jack

Jack,
Sounds like the problem is not with the D2 coils, but with the machine itself killing the coils!

One thing I'm confused on, when you say overload at RX15 on the test, do you mean it gives the same overload tone as it makes over a large piece of metal? or is the operation unstable just chirping away every few seconds?

I specifically get the overload tone. Not only does it present the overload tone, but individual programs I have set up for the coil do not function without turning RX and DS down significantly. I tried multiple test locations to rule out EMI. I really can't imagine the V3 would be killing coils. My V-rated 950 is working great. I finished my hunt with it. Thanks for the feed back.

Jack

I feel for ya' Bro , I once had to send 2 machines ( not White's ) in for repair at one time ( and it took more than a month and a half to get them back ). Meanwhile my larger coil on my remaining machine (also not a White's ) took a dump and I sent it in ) . The coil came back repaired in about
a couple of weeks along with a form letter saying they replaced with a new coil . I knew it was the same coil because there was a distinctive scratch I had put on it . So for a couple of weeks all I had was the one machine with a tiny sniper coil ( I did find a couple of shallow silver Roosies and quite a bit of clad with it though) . This machine ( which I bought used ) was an earlier predecessor to that company's latest top of the line detector and although I did find a couple of spectacular shallow finds with it I later traded it because The build quality on it was as if it had been put together by drunken Chimps and I could never get even near the depth with it it was supposed to get . A friend of mine said he knew a guy who wanted one of these machines because of it's light weight . I disclosed my disatisfaction and all the things I repaired on this machine and he still wanted to trade his Explorer SE for it , done deal ( the SE owner had a history of shoulder problems and had come to hate the SE ) .
Now I have my butt covered by having four different detectors made by four different companies and I have muliple coils for 3 of them . All four are simple to run with the SE being the most complex . If one or three have issues I now have four and don't plan on buying any more .
Right now I'm having some issues with a 4x6 shooter coil for my M6 ( I believe it's a shorted wire)
I'll be sending that in .
It's good that you sent the whole messin , it will give White's a chance to do an autopsy and perhaps aid in finding a solution to these coil problems .I'm betting you will me making some nice finds with your old trusty friend the DFX while you are waiting .Best of luck Jack , I am rooting for you !!

Here's my biggest concerns over the coil situations. From what I gathered and this may not be correct, but I thought there was an epoxy problem which when exposed to higher temperatures or just the normal shrinkage due to drying, caused the coils to get out of null (Or out of tune so to speak). This is a problem which has me wondering? I have a 6x10 DD coil which just stopped working. I assumed a broken wire, but not sure. Since coils are not easily repairable, I just junked it and took the loss. But something is nagging me about their coil construction all together. My 4x6 DD coil for my DFX bought many, many years ago was a wonderful coil when new. But after about a year, I was unable to get it to operate at the same preamp that I got before. Also my depth was just about cut in half. I'm wondering if the epoxy problem is more noticable as the coils get larger. My 8x14DD? coil from Whites was no good from the start. I couldn't run any more than a preamp of 2 and a low sensitivity. So it seems to me that any coil I get using that same method of construction is either going to lose depth as it warps out of balance, or just die out or in the case of the very sensitive V3, would false incredibly? Any constructive thoughts from everyone would be appreciated on this theory. Have anyone elses coils just got tired and lost depth? I want a V3i as a second machine, but I can't see getting one if all of my coils will go bad on me. I buy a lot of coils too lol

Thanks Baba!

I will send it all in when I get my D2 coil and test it again. I still have the DFX to stave off withdrawal. If the time comes. I still use the 1:blackeye:12 SEF and it hits very nicely. I still feel very capable of pulling deep coins with this coil, but miss the sensitivity and super accurate frequency response of the D2. I have had a love/hate relationship with the D2 going on over 3 years now. In the last 5 months it's been a dream to use and I had not switched out coils hardly at all in that time frame. I would like to see this all resolved soon, not just for my sake, but for Whites customers in general. I know there trying to make it right now, but it's been 3 years.

Well Coinnut, I don't know much about coil construction, but I can tell you that my second D2 coil went bad after snapping on a coil cover. I have always felt that something broke loose with that gentle snap. Since then I have learned to really baby my coils now. I never leave coils in a hot car in the summertime. Windows stay cracked and I park in the shade. The vast majority of time I am hunting grass.So the coil just glides across with no bumping. I had one of the first Super12 coils made on my DFX and it is still working to this day as far as I know. I traded it to a hunting buddy for the SEF. He uses it now on the MXT. Your theory makes a lot of sense though. Thanks for the input.

That makes a lot of sense you may have a real good theory there George . I'm curious to see what others say on this . It does seem that the older style non-epoxy coil are hardier and you don't get the falsing when you hit weeds and twigs . This may be a dumb question but do most , all or any detector companies test each and every coil before they put it in the box ?

I would think that there is some kind of quality control in place. I have never had a bad coil off the shelf.

I'm pretty sure every company tests their coils to some extent. What worries me is that it's possible that all of our coils are getting out of adjustment as soon as we start using them. If there is an issue with any make of detector's coils, then we have some thinking to do. I know some coils seem to be industructable and others are gone very soon after. I'm wondering if all makes of coils use the same packing method to set their coil wire with. This may be the reason some people have done side by side comparisons of the same machines with the same settings and on the same marked, non dug targets and got different results. We have always blamed that on the machine being made on a Monday or Friday lol But it may just be the coils all along. There has got to be an easy way to set the coils or maybe just leave an adjustment screw on the bottom of the coil that we can tune them with every once in a while. There must be some kind of variable coil that can be adjusted, like a potentiometer is for resistance. They could even offer tune ups of the machine and make some money lol Yep send in your machine and we will recalibrate the ground balance settings and adjust your coil back to specks ;) Sounds like an easy fix to me lol Just wondering although I don't think the detecting companies will think my idea is any good :-\

Tesoro has been doing this for some time and you can submit more than one coil to have adjusted to a machine and it is usually free of charge . You can also send in a sample of dirt to have one of their non - self ground balancing machines adjusted to .
