I have chosen  now to spend my money on other things! And now i have taken up  running again i doubt i have the energy to start detecting again! And I certainly will not act on any demands from a liar, a defamer and one who lost his forum due to his appalling conduct.

Sure, machines are beautiful and quiet...No colour or anything!

Not true! Over very hot  and variable ground  less sensitive coils may perform as well as the new generation coils simply because with the new coils you may have to  dramatically reduce the detectors gain to lower the noise level to the point where you will be able to hear weaker target signals! With coils their is no free lunch, if the coils are much more sensitive to conductive target signals then they are more sensitive to mineralized ground and stochastic EMI.

According to who?
You consistently make claims as fact, based on nothing but assumption of someone else's claims and reviews, then go on to criticize and rebuke based on your "observations", those that are actually out there doing the practical work you avoid.
Where is you personal use of said coils?
If not you? On who's use of the coils are you failing to acknowledge and take credit for?
We all know these aren't TDI results and claims!!

The guru Bruce Candy you idiot!!!

" However,it was discovered that flat - wound coils have three disadvantages , especially for detecting deeper targets compared to a compact winding : a ) The greater integrated field energy transmitted into the soils causes so called VRM ( Viscous Remnant Magnetism ) " saturation " . This is manifest as a non cancelled ground balanced spurious signal when t e coil is moved within a centimeter or so of the soil surface for some , but not all , soils ;
b ) The inductance of both the receive and transmit inductive winding ( or alternatively a mono – loop single winding ) , vary more when the said winding is closer to magnetic soils that are often associated with gold fields , than a compact winding , due to the stronger winding - to - soil coupling of the flat - wound winding .This causes the ( critically ) damped decay rates to change and this in turn may be detected by the electronics and manifest as spurious signals ; and c ) The spiral winding are more sensitive to local surface soil VRM inhomogeneities , and this too causes spurious signals. In general , the advantages of spiral winding out weighs the disadvantages in soils that have relatively low VRM mineralization for detecting shallow targets , but vice  versa in soil seeking deeply buried targets,especially when used in soils that are magnetically inhomogeneous and prone to VRM saturations that have relatively high mineralization . This may result in relatively poor behaviour in some soils when seeking deeply buried targets , especially when used in soils that are magnetically inhomogeneous and prone to VRM saturation"

So you know better than coil manufacturers and consumers?
While Candy (Full respect for his innovations) is entitled to his technical opinion, it's users and finders that most listen to when new tech is introduced.
While Mr Candy may be correct, and those that spend the hours or are looking for better than sub grams will agree, recent CC Xcoil finds  and general posted finds would show a different pattern if logged.
The amount of hours the average hobbyist spends on turf is minimal. That said they are looking to find colour in the time they have available to detect.
You will find it a struggle, to find any of your Youtube posts, last 12 months, that aren't using aftermarket coils.
Those using factory, not disputing their finds, are generally ML sponsored.
Ps. As the new forum is just a database for my detecting stuff. You'll never see it!
You don't detect, and outside of calling out your theory here. You have nothing to offer anyway.
Associates that find it helpful for reference, know how to find it.
I see you wimped out after gloating, and are screening everything before poting (24hrs, 48hrs later) when you're ready!

  You are an idiotic ignoramus par excellence. You are implying that because neither myself or Candy detect what we say about  spiral  coils is wrong.  What Candy says is correct  and if you  looked at the  transmitted  field shapes and field densities  from the coil centers you would understand why what I say and Candy says is  correct.  And by the way the best shape for a spiral  coil's  is a square as it gives the most uniform field. Most of the improvement in coils are due using  litz wire which reduces the skin effect and proximity effects and inter winding capacitance. But  I repeat that for  highly variable  vrm  soils that spiral would coils are NOT the best choice for larger and deeper targets.

These are the advantages of  spiral would coils according to Candy
These so called spiral " flat - wound " coils have three advantages for detecting small shallow targets compared to a compact bundled winding : a ) The field generated from each turn passes closer to the target as the coil is swept over the target and hence each specific turn for the spiral coil both irradiates the target with a greater field intensity and likewise receives the decaying eddy currents in the metal target with greater sensitivity compared to each specific turn of the compact winding on average ; b ) As the coil is swept past the target , the transmit field and receiving winding sensitivity from spiral winding are laterally broader , and hence improves electronics signal - to - noise ratio ; that is , the signal from the shallow target is within the effective volume of transmitted stronger field for a longer period compared to that of a compact winding , and similarly the target is within the more sensitive areas of a spiral receive winding for longer than a compact receive winding ; and  c ) As the total volume integrated 3D ( magnetic field magnitude ) 2 for a given inductance and transmit current ( 1 / 2 / 1JB²dV ) , the same for all coils regardless of winding shape ( in the absence of permeable material )  more of the strong field of compact traditional mono loop bundle resides within or close to the perimeter of the actual bundled winding than does the field of the planar spiral winding . Hence the spiral winding has the advantage of irradiating more of its field out into the interrogated environment than the compact traditional mono - loop winding bundle , thus putting the spiral winding's field to better use for target detection .

You have never used a spiral coil, and don't detect!

So what! What  I have  said about  spiral coils is correct."Putting spiral windings even if semi spiral into the smallest coils is pushing the limits, if you then go back and put a bundle wound mono of the same size on your machine runs so much quieter and will handle ground better."

Apology? You're a testicle free DICK, I apologise for nothing!
Trying to place yourself on the same level as Candy without even using a ML machine for more than a decade by twisting  (or attempting to) my words is just pathetic!
Do you think people are going to ignore your decade plus of anti ML commentary, lack of swing time with any relevant machine and resulting lack of finds and experience, because you agree with a theory?!
And while it may be correct, unless you know where the big deep stuff lies, and have Beatty/Wilson knowledge/history, it isn't seen much by the majority of users.
Show how the theory works! Go find some colour!! You're full of crap!!
Your faked knowledge that is just plagiarised opinion is now obvious to all.

"Trying to place yourself on the same level as Candy"
No not trying to be on the same level as candy but simply showing that he agrees with me and based on a peer reviewed paper i came across where the authors plotted the field strength of a spiral wound  coil and the shape of its field. When you see this  you will understand why spiral wound coils are more sensitive and go deeper for SMALL targets but  will not be optimal for larger targets at depth. You idiot you cannnot defeat the laws of electo magnetics and i don't revile from my critisms of ML. Everyone can now see why your  "forum     was closed down. Attached is a figure  for a square spiral wound coil.

You obviously have no idea of what the pictures show and if you are to be believed the biot savart law for coils does not apply to spiral wound coils! But the facts are that what  Candy and I say  about spiral  wound coils is correct and can easily be proved by  some simple tests on  conductive objects of  varying sizes. Its the same reason that over very hot and variable ground that you have to run a spiral coil at  a lower gain compared to a bundle wound coil and also why a spiral wound coils  pick up more EMI compared to  bundle wound coils.Once again you prove that you have no idea of what you are talking about!!
