Aspire Triton 2 tank is an upgraded version of Triton 1. This tank brings you adjustable airflow control that will allow the user to really dial in on their desired airflow setting. Two notched fins act as a heat sink, to dissipate heat away from the drip tip, and also as a grip for unscrewing the Triton 2's drip tip system. It not only can use 0.3,0.4,1.8,0.15ohm coils but also support a new coil of 0.5ohm. With a kanthal base wire and a kanthal wrap these coils provide more surface area compared to standard coil designs. This results in greater vapor production which gives a noticeable increase in flavor. The Triton 2 also brings users an optional RTA system you have all been asking for. This RTA system is simple and easy to use but still brings users all of the things they love about building their own coils.
