Here is a nice looking concentric coil for for just 20USD. Looks nice enough for the price. Perhaps it can be used for some self made unit like the TGSL or IDX. I wonder what the coil parameters are? Cheap.https://www.aliexpress.com/item/4000...1d61c04e8a0-47

Chinese gold bug Pro with two coils! Just 150USD. I saw on YouTube the issue is with the coils. When the guy put on an original coil, the unit worked great.https://www.aliexpress.com/item/3286...e804dd11288-15

Attention: This product is a high copy made in China. If you mind it, please don't buy it.

From the site, at least they are honest crooks.

6.29kHz hmmm...This coil may work for IDX, with a little tweaking. Good for experimentation. Buy 1, get 3 free?? Well that's a great deal!

Here is a steal of a deal. The AR944 control box for 28USD. Videos on you tube show a very good non-motion discriminator. Just make a DD coil and you're in the game.https://www.aliexpress.com/item/3276...chweb201603_55
Or you can get complete unit for 84USD.https://www.aliexpress.com/item/3283...chweb201603_55

All sun Ts180, not bad for 60USD. Youtube videos show quite OK performance.https://www.aliexpress.com/item/3297...chweb201603_55

Bounty hunter junior TID metal detector??? Just 38USD!! Unbelievable. If you change the coil and tweak with the electronics, I'm sure you can have quite good detector. Then you can put in a "little man" package. I wonder if the performance is the same.https://www.aliexpress.com/item/33028134809.html

Why do you keep pointing out how the prices are "UNBELIEVABLE" ? Their R & D costs are pretty low, I think.

Ok, I stop using that word. That word does not refer to the prices but to the gall and unmitigated temerity of the chinese people.
There R & D cost consists of ripping off the intellectual property of other corporations. Unbelievable! OH,OH.

Maybe you are right. It is incredible the prices they can offer on electronic modules and other stuff. There has never been a better time to be an electronics hobbyist.

Any coils you see that can run on a pi, waterproof, and under 10uS?
Rather buy than make...
