Want to gather some information

Kanger's website isn't clear but it does say that the aero uses a pro tank 3 coil (dual coil)

Others have said that the pro tank 3 will accept a single coil from a pro tank 2 but that the pro tank 2 will not accept a dual coil.

As far as the pro tank 3 and the aero tank, the coils are interchangeable so you can get whatever ohm you want, but unless you are using a variable voltage battery or a Mod you would be good to stick around 2.0 on the coil

So whats the difference between this single coil and dual coil?
