Thank you for your answer and effort Robby_H.



Ok, but I haven't read the real significant reason, why the Moodz coil (the spider wound coil shown), when shielded would outperform a ML coil. All I get is an indirect indication of the fact.


Forget the known facts like proximity effect, skin effect, lower capacitance, coil resistance..
Next try.
Who is smart enough?

Cheers,

facts are if you bundle wind or basket weave a 45 cm coil which is what I made and stick it in a pizza box none of you will be able to tell the difference on depth or sensitivity.

If you are comparing your coil in a Pizza box with a Pizza Hut Meat Lovers Special also in a Pizza box, I can believe you will not be able to tell the difference on depth or sensitivity. I don't think your mate DougAEGPoof will be able to tell the difference either!

Must have been amateur hour at coil trek ... Probably the plonker team on shift when they made that one ( ie Robby , patches an his little wannabe peter99 ... )

Why the antagonism to Moodz? As Carl would say he is not hurting anybody or any company and what he is doing will stand or fall on its merits which will be decided not by Moodz but by the users and ultimately the market!None of you have his circuits or have any idea of his signal processing methods or the results of any field trials! All you have is what Moodz has posted! So any negative comments in my view have little or no technical merit or validity and are purely speculative or are more likely an attempt by those with a vested interest in maintaining the status quo and are directed to trying to damage his reputation or discredit him either directly or by association!

[Doug2]

You turn every discussion into a farce!!! You're like a child who reads a few words and then pretends to know it all. Someone once said "Never argue with an idiot, they will drag you down to their level and beat you with experience". That's you Doug so please go away and stop bothering the grown ups!!

Typical response from someone who claims his only association with a certain company is that he gets their newsletter and who has posted lies about me on other US forums!!!! Its the typical response from someone who represents i believe a vested interest and will do all in his bird power to preserve the detector market status quo! But the fact remains that the spider wound mono performed better than any commercial coil in the field over typical gold field ground and that is all that matters!!! What a poor show it is when you have to cover for people like Patches Junior!

[Doug2]

Doug, I give free high tech answers to my mates. But guess what, you are not a mate of mine. So any technical questions you want answered are going to cost you. How much are you willing to pay?

Why would i pay someone who clearly does NOT know the answers to my questions? Now prove me wrong!l Many folk here i am sure would be interested in your thoughts on the relevance or otherwise of coil Q and Pi detectors and the pro's and cons of spider vs bundle wound coils.

I want a response from patches junior please not a parrot!!!
Ps the coil I used WAS used over some typical gold field ground!!!!!!!!!!!!!!!

I see you usual ignorance is coming to the fore again Doug. Robby_H is just a little too smart and logical for you so, as usual, your only recourse is to attempt to belittle him?

Ps the coil I used WAS used over some typical gold field ground!!!!!!!!!!!!!!!

And so your gut feeling was that this coil was better ;-)

Tell us all about the rigorous testing processes you went through to reach your conclusions Doug, and define the performance parameters that were so much better! Now this will be interesting!!

[Doug2]

I had a coil that was made from a old crystal radio antenna that was better than the spider "would" coil you used. It detected gold down to 4 meters deep. Prove me wrong.

Plus what happened to the detector this thread was named after
field test unit no 001 "model T"

Please be kind enough to answer these questions i asked you in a previous post thank you!
"Doug, Doug, Doug. Moodz has not even tried this coil on a detector yet!'
If I don't know the answer to this then how would you know?
However do agree with me that coil losses caused by : distributed-capacitance losses,skin effect,proximity effect,eddy-current losses in neighboring objects can be reduced by using spider wound coils? ie do you believe that higher Q coils in metal detectors are desirable? If not could you be so kind as to explain why.

[Doug2]

What is the point if we have to wind the gain back!!!!!!! And I remember you saying that the QED worked just as well with low Q coils. You change your arguments like most people change their socks!!!!

For the umpteenth time, there is a difference between waving a coil over well blended ground at some test site and over typical variable gold field ground!!!

The spider would mono coil I used gave an advantage over ANY commercial coil!!!!!!!!!!!

Doug, there is a big difference between DO WORK and giving AN ADVANTAGE.

I knew your answer would be close to what you said.

Well lets see Mootz prove he has finished it and compared it to a popular coil used on a Minelab PI. I say he has not finished it and done a field test on it. Wanna Bet?

So as you would say "The onus is on Moodz to prove me wrong"

Please no more waffling Doug. 15 years of promoting your crap that has produced nothing is getting a bit tiring.
