Let's Invent Another Metal Detecting Coil

[Aziz]

Hi all,

I have revisited the idea of half-space magnetic field shielding (post #14). Has absolutely no merit. At least not for us hobbyists.
First of all, I didn't have an ultra high magnetic susceptible non-conducting material. I had a low susceptible mixture of maghemite and hematite. Secondy, it was difficult to make the form of the magnetic shield. Third: Too heavy. Not convenient for coils. Fourth: The magnetic shield effect improvement (shielding the EMI noise) is not significant. I couldn't even see any shielding effect. We would require something like Mu-metal feature (µr = 50,000 - 140,000). But Mu-metal is conducting.

Best way is still using the anti-interference coil configurations.


Ok, we have to invent something different. I'm ready for ideas...

So, what do you trying to say, Aziz????

What.... you want someone to come up with ideas that actually work, do you????

Hell, ideas that work.... gee, that would be one hell of a change for you, Aziz!!

Ufox,
you didn't obviously understand the principle of teamwork. Did you?
Look back and see what we have achieved so far. Would you like to contribute too?
Have you a brilliant idea for a new coil?

Is that where a bloke waffles on within a group of blokes for years about having the WBGB when he actually has completely and utterly nothing??

UFox, you and your mates don't deserve my WBGB! Period.

Hell, Asif, what would be worse than being forced to use one detector fitted with your ground balance would be to be forced to use two detectors fitted with your ground balance!! So you are right, we don't deserve to be punished like that!!!!

OK guys, let's end it there. You've both made your point, and now it's time to move on.

If Aziz actually had the WBGB (as he claims) then he would either have built a working model to demonstrate the principle, and consequently sold the idea to a detector company, or have published the details here as a spoiler to prevent it being patented. Neither have happened, so I can only assume it only exists as vapourware (or vaporware, if you're in the U.S.)

Let's leave it there and not hear anything more about it ... please.

Hi Davor,

2box is well known. There is nothing to investigate or improve.
Aziz

I missed to reply here because I expected something to evolve, but it didn't. My idea in revisiting a 2box is employing it for PI in a mode that is not strictly balanced, but aimed to straighten the response curve. E.g. to put emphasis on deeper targets, while reducing the surface. I expect improvement on viscous grounds, and some reduction in dynamic span of a Rx front end.

There is a nice phrase in English (mostly UK) : hogwash!
I like it!
It's funny to use it in proper moments.
Ok.
Unless one change basic operating principle of conventional metal detector, the same one can't expect to invent something fresh new.
He can only reinvent the wheel all over again. Or in Serbian: he can only reinvent the hot water all over again.
I am maybe a pessimist on these matters; but i think that everything is already invented, in borders of basic operating principle of conventional metal detector.
So, my suggestion would be: do not think conventionally, do think unconventionally!
Try to find a way to change the basics, don't try to extend the basics.
Cheers!
