The Smok Nord has two coil options available currently; one is a mouth to lung (MTL) style of inhale and the other is a direct to lung style (DTL) of inhale.
These two coils make the Nord a surprisingly versatile little device. The 0.6ohm mesh coil for sub ohm offers users an impressive level of flavor and cloud with a reasonably open airflow. The 1.4ohm regular coil tightens up the airflow and reduces the volume of vapor created, which is very useful if you are using salt based nicotine (salt nic).
These coils are sold in a pack of 5.
