I have a smokAl tank and and using a rebuidable DIY coil. It is a dual coil. I am using 28 guage wire and using 12 wraps. When I fire up my battery it says my resistance is 1.2 ohms. Is it not supposed to be lower ohms. It tastes alot stongerr than it does when I use the ready built coils. Help!! How many wraps should I use?
