Try the new Triton Mini 1.8 Clapton coils. They fit and vape way, wayyyyy better in the Nautilus Mini than the BVC coils. And I use Ripe Vapes VCT juice in 12mg. Perfect flavor for the Nautilus (especially after it ages for a week or so).
I've had my Nautilus Mini for a long time. The sub ohm stuff is great all (The Aspire Cleito with the new stainless TC compatible coils rules) but I still love the Nautilus for when I want to carry around a smaller setup without the megaclouds in public.
Anyway, like every other tank I've used, a little bit of juice collects in the base (airflow control area) under where the coil screws in with my Nautilus. It gets all over the spring part and probably affects the resistance reading. With the Nautilus it turns dark though so I feel like it's "cooking" a bit too. Any way to avoid this? I usually spray it out with Duster then soak in soap (Cetaphil Gentle Skin Cleanser, simple with no added fragrance or anything). The soap is important because you'll taste the bitterant chemical from the Duster otherwise. (Learned that the hard way).
I think this may have something to do with the age of my Nautilus. I've had it for so long and used and abused it and smashed it in my pocket, etc. So maybe I just need a new one. The thing is basically indestructible but after a few years of abuse anything will show it's age.
I feel like the Nautilus is inappropriately deemed a "noob tank" but they're still popular because people who "sub-ohm" don't want to blow big clouds in public all the time. So it's still popular I believe. And since it's popular, they need to make a damn top fill one already!!
