I hate the term "Sub Ohm" for a couple of different reasons. For one, it has obviously and quickly become a buzz word and many new vapors are quickly lead to the false idea that this is what they need to do to get a good vape. Secondly, from the other perspective, a "sub ohm" coil build has been falsely labeled as inherently dangerous. Also, not true.
And for what it's worth, this morning I built a .8Ω microcoil which I am currently vaping on quite comfortably and enjoying thoroughly on an unregulated mechanical mod.
The difference between me and many other new vapers learning how to build their first atomizers, no matter whether it's a microcoil, a standard wrapped coil, above or below 1Ω, is that I understand how to properly test the resistance of my build and calculate the current it will draw on my battery, as well as having an understanding of the rate of current flow my batteries can handle
Ohm's law is simple math, and I don't need a calculator to figure if my build is safe. I can do that in my head. What has to be learned is how to properly test an atomizer, whether it's with a meter or one of those 510 resistance testers and then properly figure the current draw using a simple math equation. To much current draw on your build for your battery? Back to the drawing board.
The method at which the coil is wrapped is very secondary in regards to your safety.
