It’s interchangeable with 1.6ohm and 1.8ohm regular Nautilus coil, however, only the 1.8ohm coil with green seal gasket and NS mark is appropriate for nicotine salts. We suggest using the 1.8ohm coil with NS mark only with Nautilus AIO device. The Nautilus 0.7ohm coil cannot be used with Nautilus AIO.
