@kross8 - There's 2 different coils that Kanger makes for the PT2. Both are sold in a small black box, and come in 1.5, 1.8, 2.2, and 2.5 ohms. Only difference between them is that the second ones are SOCC and usually alittle more expensive than the first ones.
First ones are marked:

for Protank & EVOD & Unitank
Second ones are marked:

MT32Coil (SOCC)
Japanese Organic Cotton Wick
I've been buying them for a few years now from DesertVapes, since she has good prices regularly, and when she has a sale..they're really less than other places.
