When they work, these are the best coils for any Nautilus tank to handle Nic Salts.
Effectively they are just a standard 1.8 with a larger wicking hole - but this actually makes a big difference. The standard 1.8 didn't wick salts properly and the 0.7 & 0.4 are way too hot for Salts with hardly any vapour production in my opinion.
However, these are the most inconsistent coils I have seen from Aspire (as others have mentioned). Luckily I didn't get any duds, but some spat, some had slow ramp up speeds and a couple with incredibly tight airflow.
Frustrated with how Salts performed in my Nautilus GT - I decided to switch from Salts back to free base Nic and you know what? I actually get a much satisfying hit.
This may not be the answer that people want to hear, but for me, being a Nautilus Junkie for over 6 years and trying every coil and eliquid combination. The trusty 0.7's, with a good free base (50-60VG) nic eliquid, with NO added sweeteners! At a nic strength of your choice - at around 17 to 21 watts gives the most satisfying vape with excellent and consistant coil life.
If you want to vape salts, I recommend purchasing the Uwell Caliburn,
