Selling your own designed & built metal detectors

[Teleno]

As long as what you sell is completely non-functional then you are probably OK. But one of the most painful things you can do is build coils, especially for VLF. Instead, consider a design that uses an existing coil, preferably one that is plentiful & cheap.

Certainly it's a pain.

Care to name a couple of plentiful coils? I need monocoils around 600uH.

If you need a mono coil, then the answer is to design for 300uH. There are a bazillion of those.

Coils are not a problem. Vlf or Pi. Contact any european manufacturer (detech, nel..) and ask for a custom coil, and prepay for 20-30 pieces.

That's interesting... any idea what they charge?

Take for example SEF VLF detech coil for golden mask 4, 10". Bought one for 100 usd 2 months ago from a store, reseller. If you come to an agreement as bulk pricing order of 20 with the manufacturer, even at 2000$ for the whole order without any discount at all you're still good as you still end up with excellent coil quality and not having to worry about the coils. And i think you're going to get at least 20% reseller / bulk pricing discount. These manufacturers do make coils for all brands and models so shouldnt be a problem with customization, (custom specs coils)

There is something seriously wrong in these people minds.
This "China mass production&trade miracle" will come to its end sooner than it started.
These kind of people are really deep sick.
I don't have other term for this.
My vocabulary is limited for this kind of behavior.

It is called "collective lunacy" ( my term ). Defined as : sociopathic behaviour which spreads "en masse" across the society, spawned by some false notion of working towards a greater cause, in this case, world domination. It is akin to megalomania on a grand scale.

No wonder why coronavirus appeared there.
Maybe natural selection?
