Question regarding Purity

[Stannoman]

I recently heard some stuff about implementing purity and then getting rid of purity again.
My question: Does the purity of dowsing rods still have any use? Was it perhaps something else that was removed or changed?
Basically I have been trying to find a mine nearby using a 0% Pure Woo-Woo-Rod, I haven't found anything in hours, while trying out the tactics described on the wiki, and forums. I read that if you use different purity rods, you find different nodes, so if I used for example 4% dowsing rods, would I theoretically find different nodes? Or was, like I said before, something changed with all this purity stuff and now it doesn't matter?

Thanks in advance.

Different purity values of dowsing rods will find different mines. They find mines with similar elemental composition to the rods, which means of similar (and possibly higher) purity.

You find different sets of mines with different purity rods. So you might have a mine near you of a different purity than 0%

Dowsing is also kinda tricky. Just walk in a grid pattern.
