Users can use Nautilus BVC 1.8ohm and 1.6ohm coils on the Nautilus AIO, however, only the 1.8ohm coil with green seal gasket and NS mark is appropriate for use with nicotine salts. We suggest using the 1.8ohm coil with NS mark only with Nautilus AIO device. The Nautilus 2, 0.7ohm coil or Nautilus 2S 0.4ohm coil and Triton mini 1.2ohm, 1.8Ohm and 0.15ohm cannot be used with Nautilus AIO.
