White's To Produce 5.3 (6") Concentric Coil For MX Sport?

Recommended Posts

Speaking of the mx sport and coils, it looks like Whites is working on making a 5.3! There is a thread on another forum and tboykin is asking for testers. I would try an take him up on the offer only I don't know the first thing about being a tester and have my plate full with work for a couple weeks. I've tried the big coils before but usually find myself using the smaller ones 90% of myself. As soon as the 5.3 is ready for prime time I'll be picking one up!

I like the 5.3 (6" round) except for the fact it is twice as thick as it should be. White's is still using molds from the last century. That said the only coil I own for my DFX besides the Bigfoot is a 5.3 concentric. It would be a good dry land coil on the MX Sport but the 7" DeTech DD would be better for in water use unless White's puts a little epoxy in the new 5.3, and that probably is not a good idea.

I've had what you call a 5.3 coil on my Eagle 2 for over 25 years and loved it. That what I wanted in the first place but at the time it had to be the Detech 7 " or nothing. I do like the coil as said on other post. I'm not sure if I'll buy it now being the 7 is doing what I wanted in the beginning.

I don't see me putting out money to buy the 13 when the coils I got now from White's fill my needs.

I've never liked the 5.3.  I don't the form or the way it swings.    I wish they'd make a 7" concentric instead.

Yeah Mike, I wish White's would ditch all the old molds and start over. They need to look at the 7" concentric shipping with the new Tesoro Mojave to see how coils should be made. White's old thick foam filled coils hark back to the 1970's and are actually kind of embarrassing at this point. I think some of the performance edge some detectors enjoy these days has less to do with the detector and more to do with properly designed high performance coils that have been mated to them.

White's hooking up with DeTech was not a bad move in that regard, in an least jump starting a supply of modern coils for their machines.

The main reason people like the 5.3 is only because it is the only small concentric option available, which is why I have mine. But it sure is not because it is a great design compared to other small concentrics out there. Great point and well worth White's hearing it. Thanks Mike.

Seriously, I though about grabbing a Mojave just to get the coil, as the detector with coil costs less than many coils on the market these days!

Steve, I agree that these series of smaller Concentric search coils could be made with a thinner, flat-bottom design with a different bottom half.  They could also make them in an open-frame design, and I know at one time when Carl M. was there, he had such a prototype configuration he showed me and I was getting my hopes up ... but up-line they said to put it on the back burner.  WAaaay back I guess.

There is, however, a benefit for some people by using the thicker-bodied, semi-dome shaped lower-portion 6½" Concentric coil, and that is on some models for many hunting applications, het helps maintain a proper, or better, coil-to-ground relationship which can help eliminate overload.

Most manufacturers today use a higher gain or Sensitivity level that some of their former models, and that can create an 'overload' or warping of the EMF due to intense ground mineralization.  It can also cut down on some 'overload' caused by being too close to metal objects.

Most detector  manuals will suggest working the search coil about 1" to 2" off the ground, and the thicker-bodied 6½" Concentric helps detecting folks do that.  Search coils shouldn't be scrubbed on the ground but instead worked a small distance off the ground, and the 6½" coil design helps keep the internal windings at a or functional distance.

Chuck,  I didn't care for the MX Sport's release for one reason and that was there was not a smaller-size search coil.  Then they introduced the 7" DD from Detech and I tried it on a couple of MX Sport units earlier this year, and it did some of what I wanted a smaller-size search coil to do.  I just wanted a land-based model.

Then a few weeks ago I drove across-state to buy my first MX-7, at which time I also bought the 7" Detech DD and some accessories, and also was provided a freshly assembled 6½ Inch Concentric coil.  It needed to be put together and sealed, and came w/o a decal, so I had my oldest son design a custom decal for me when he got the halves sealed together.  That decal is seen in the link as Steve H. provided above, and shown here.

Also, a reminder for those not familiar with how marketing folks get involved with naming products:  The former White's coils labeled 600 Blue Max, 5.3 Black Max, 5.3 BullsEye and 5.3 Eclipse are NOT a physical 5.3 anything!  Physically, to our eyes as we view them, these excellent search coils measure closer to 6½ Inches in diameter.  Also, the search coil decals used in the past didn't tell the consumer what the internal winding configuration was,  whether Concentric or Double-D.

As seen, the decal my son made for me for my MX-7 "tells it like it is" by describing the size/diameter, as 6½ Inch, as well as the internal layout of the coil's windings, as a Concentric coil type.

I believe you might re-think your feelings about owning and using this excellent size and type search coil, if you get an opportunity to check out the new 6½ Inch Concentric coil against your 7" Detech DD.  I don't mind owning both of these coils, plus the standard 950 Concentric, but the 6½ Inch Concentric equipped MX-7 will see more field-time, to be  sure, and I'l alternate between the 7" Double-D and 950 Concentric on my 2nd MX-7.  Mainly keeping the 7" DD mounted for the next 3-4 months just to do side-by-side comparisons between these two closely-sized search coils on naturally located targets afield.

I like the concentric over s DD coil but I’m not sure if I’ll get one. I got another detector on order and I know it will be money out for a coil there.

In my opinion you can’t go wrong on the MX Sport.

The main thing you enjoy it and find lots.

This re-invigorated thread reminded my of one of my DiY mods from over a year ago which I was going to write up but never did.  Cutting to the chase (see photos below) is a modification I made to a White's TDI SuperPulse 150 (that's the nominal coil enclosure OD in mm, so about 6 inches) with two things in mind:  reduce the thickness and add enough weight to make it neutral buoyant or negative buoyant (that is, sinkable).  As you can see I definitely accomplished my first goal.  The second goal was met but I had to add a T-handle to supplement the S-handle on the rod so that torque and balance would work and get the coil to sink when mounted to the detector.  Anyway, pictures are worth a thousand words.  I replaced the truncated cone lower coil cap section with a coil cover (don't know what brand coil cover but it was oversized about about 3/4 inch in diameter).  It was still waterproof last time I checked.  The weights added to make it sink were limestone drink coasters.  The middle photo shows the top housing (lower housing ground wire disconnected) of the mono coil assembly.  Oh, and there was no foam inside the factory sealed SuperPulse 150.   What you see in the middle photo is exactly as found when I opened it up.  The coil assembly on the left in both top and bottom photos is a Miner John 5"x9" mono with its coil cover attached in the last photo but not the first.

      I’ve been trying to find the time to truly give the 6” Six Shooter coil a field test.
      I had the opportunity several times to give it that test but always fall short of what I wanted.
      Today I found myself in a school yard that I never hunted before. On the way in to what I would call a very large play ground area. They had to haul loads of sand in because it so deep I found it hard to walk on.
      I had fired up my Sport as soon as I walk in the play grounds. On the way to that beautiful deep sand that I was thinking it had to be hundreds of coins waiting just for me I past some very small bleachers . I made a swing a two but no luck. That sand around the swings was calling even louder now.
      I started my hunt around the first set of swings but to my disappointment not one coin did I find. This went on from one play area to another. Oh I’d find a penny now and then but not much I’d say to write home about. I’d walked back to the first swings that I had started from.
      Standing there I couldn’t believe I hadn’t no more than I did . My thinking it’s got to be someone hunting this school everyday. I’ve never walked away with something looking this good and so little.
      I was not to be put down so I started detecting again. After a few swings I got a signal within a foot circle all reading a quarter. Sure enough it was a quarter not just one but three. From then on I stayed away from the play ground equipment. I was finding pennies dimes with a quarter here and there.
      Yes I know any coil could have done what I’ve talked about so far.
      I was feeling so good on the coins I found so far I was going to hit those metal bleachers on the way out.
      The Six Shooter coil really was shining bright when I was hunting right under that bottom seat that you can see in the picture.I found more coins next to all that metal than I found in that big play ground.
      I know it’s more coins to be found under that little bleachers. I would have tried to move it but I think it would have made a change on my out look on life.
      I think the people detecting before me didn’t have a small coil like the Six Shooter coil like I did. If they had my finds would been lots less.
      If you don’t have the Six Shooter and you have the MX 7 or the Sport then you don’t know what you’re missing.

      I was in a bookstore and pick up a copy of Western & Eastern Treasure mag. I flipped over to the inside of the front page and low & behold was a big blow up of the MX Sport. You may say what the big deal being I have one. What put me in a state of shock Is when I read Waterproof Headphones Included.
      The price is the same as it always been. All I can say is people is if you’re looking for a great buy look no further. Look down in the left hand corner of the picture at the number of coils that White’s offer for the Sport.

      The furor over the White's MX Sport seems to be gathering force on other forums but has long since been old news on this forum. As such it has run out of steam and I prefer no more threads be started over the problems with the MX Sport. For those who wish to keep going round and round about the issues with the MX Sport there are two threads currently running at http://www.treasurenet.com/forums/white-s/509514-mx-sport-trouble.html and http://www.dankowskidetectors.com/discussions/read.php?2,109780
      My advice is simple. If you do not have an MX Sport there is no rush to get one until there is some way to clearly tell what it is exactly that you are buying. There are various versions of the machine in the distributor and dealer pipeline, and apparently nobody can tell if a machine in a box has the latest version of the firmware AND that it has a face plate that is not going to crack in the first year or two. And frankly, in my opinion the latest version of the firmware is not likely to be the last.
      OFFICIAL WHITE'S RESPONSE TO ISSUES 7/20/16 - http://forums.whiteselectronics.com/showthread.php?76138-MX-Sport-Screen-inspection
      "If your SAT goes to "EIGHT" and you "DO NOT" have any cracks in the clear part of the display, DO NOT send it in for updating.

      If your SAT only goes to (6), and/or... you "do have" cracks in your display, DO send it in for updating.

      As mentioned prior, the serial number sequence will not tell a person if it needs to be updated, nor if display cracks are possible.

      We are sorry for all this and are working hard to resolve any and all issues as quickly as possible.

      Again, 

      "EIGHT" SAT, no cracks, NO need for updating.

      (6) SAT, and/or cracks, DO send it in for updating."
      ACCORDING TO INFORMATION ON THE THREAD THERE IS NO WAY TO DETERMINE VISUALLY OR VIA SERIAL NUMBER WHETHER THE SCREEN WILL CRACK BEFORE HAND.

      If for any reason anyone believes they have ANY issue with an MX Sport that they think should be taken care of under warranty, then contact White's directly and get it resolved to your satisfaction. Or get a refund for the unit if you can. Or sell it and move on. I have.

      An error in VDI number and quarter/dime reporting has been noted in the early version of the new 6” concentric coil for the White’s MX series. I can’t imagine not digging anything reading in this range anyway, but it is something to be aware of. If nothing else it could affect resale value on the coils so if you have one and this is a problem it can be addressed under warranty once a fix is applied. Stay tuned.

      Like said when I turn on my Sport I get this frying sound for about 1 1/2 seconds..When I turn off the volume all the way I still get the frying sound coming through. I have other coils but this my first time of hearing this.
      If anyone else has this new concentric 6” please let me know if you too having the same trouble.
      I’m really not sure if it is trouble being the coil is working great.

      There are times when 6" is more than enough. I could take those jokes further but this is a family forum.
