I have had one of these for years and the right size makes all the difference. Some fun things include the ability to feel where the metal studs are in building walls, where the electrical lines are under the ground and of course the microwave. The most interesting part is how I conceptually had thought of electrical fields as 2d (because of pictures and school), but in reality they are 3d and so it is like reaching into a sphere of various sizes, the deeper you go in this sphere the stronger the field.

May I ask if you have a recommended style or material that you prefer for sensing? The idea of sensing EM fields is fascinating to me but I've never quite made the leap to an implant. I didn't realize these kinds of rings exist.

If you mean ring type I don't remember which one worked best, sorry.

As for my favorite EM field there is a nearby street with buried powers lines and transformer boxes at ground level. As you walk the street to the main street each box has a bigger EM sphere and I like to let my hand coast over each sphere. It isn't a sphere per say, but only in the sense that at at certain depth in the field the density (for lack of a better term) becomes high enough that I can feel it and it is like a boundary line
