There are a lot more questions and info you need to have depending on how low you want to go if you want to sub-ohm. If 1 ohm is your preferred, then "almost" any good
mod will fire that. But you'll need to evaluate your....
mod, battery and
tank/dripper your using. 24 gauge is big wire to start with and without doing a ton of wraps, won't get 1 ohm, say 13 to 14 wraps. And if your running a low power mod, won't work very well due to ramp up time (how long does it take to heat up) and amps needed to fire it.
Definetly use an Ohms law calculator!
