My coil build is 3mm dia, SN reports it to be 0.15 ohmns. When triggered it reads 0.31. Vapeing it at 40W 200c. Total 8 wraps (4 & 4) with Japanese cotton. However just about any coil I put in the SN reads 0.1 to .015. I just got the SN a few weeks ago and I think mine may not be reading them right. If I build a 5 or 10 wrap, it reads the same. But I don't care, the SN has no problem delivering a fine vape.
I didn't know what to expect with this thing, but I've run a few
tanks now, and no doubt this is the best coil I used to date. The flavor is amazing. Totally explodes in your mouth. In fact I usually set my TC temp at 270c. With this coil I'm at 200c and it's a much better vape.
Doing this with nickle was a bit harder because it is so soft to work with, but well worth the effort. You should give it a go and see for yourself. Getting much more clouds than a straight coil.
Next one I do will be a 10 wrap. I love this TC stuff. It gives you way more latitude when building
coils.
