The AGA-T2 should work just as well with a SigMax as it does with a mech mod. You just need to get the coil built that is compatible with it. Their is loads of instructional videos on YouTube that give detailed instruction on how to set it up as well as the preferred materials to use. It always helps me to have the visual example when doing something the first time. Just go on YouTube and search AGA-T atomizers and you will get a list of different instructors doing instructional builds. I hope this will be helpful.
