The Nautilus 2 features top fill access, allowing for an easy fill on the go, and this tank also conveniently holds 2ml of E-liquid, so now you have longer periods between each fill-up. As always we strive to bring satisfaction to every type of vaper out there, and that is why we offer 5 different settings when it comes to our precise airflow system. Whether you are a mouth to lung vaper or direct lung vaper you can be rest assured the settings can be switched to your liking. The Nautilus 2 comes with two different coils; 0.7ohms which fires between 18-23watts (direct lung vaper) and the 1.8ohms coil and this one fires between 10- 14watts (mouth to lung). The Nautilus 2 is sported in 5 different colors; stainless steel, black, red, and grey.
