Little vapor production no matter what I do

[ian-field]

Alright guys, thanks so much for the replies, I bought my new IMR high drain battery, its capable of sub ohm builds, I have a new dual coil setup that was done for me by the shop as well, im getting more vapor than I did before but I thought a 0.7 ohm build (measured with my multimeter) would produce a little more vapor.

I've just had 2 manufactured dud coils in a row, and one DIY that somehow I just couldn't get going right.

Sometimes you just have to keep trying!
