The new Nautilus AIO comes with two 1.8 ohm coils -- one regular and one for nic salt. Both are fine for regular juice, but use the nic salt coil when vaping nic salt. What is the difference between the two coils. I know how that are indicated (green seal), but how is the coil different? Some say that nic salt burns coils quicker. Is it only an issue with high nic juice (36mg+)? The Nautilus coils for AIO are listed separately at the Canadian distributor. Is there a difference between those coils and 1.8 coils for the Nautilus Mini?
