Discover just how great vaping can be when you use the right hardware. The Nautilus mini by Aspire utilizes their proprietary BVC coil technology which stands for Bottom Vertical Coil which in layman's terms means 'best flavor and great vapor'. From the adjustable air flow, to the Pyrex glass tank, to the finely engineered chassis this tank is screaming high quality at every turn. The Nautilus Mini starter kit features a 510 thread (which will work on any 510 thread battery) 2 ea coils, a 'reducer sleeve' and a getting started instruction booklet. This Nautilus Mini tank is a MTL (mouth to lung) tank, but can be adjusted to also serve DTL (direct to lung) hits. Coils are super easy to change, the tank doesn't leak or slurp and is impossible to overfill. Best of both worlds, the Nautilus Mini is the right tank for you.
