The Atlantis is a subohm tank while the Nautilus is not. If your mod cannot handle subohm, then it won't work. The Atlantic will go through way more juice than the Nautilus. The Atlantis, much like the Kanger Subtank, is designed more for the direct to lung vaper. If you are a mouth to lung vaper, you will not like it as much. The Nautilus will work great for either the lung vaper or the mouth to lung vaper.
