The new Aspire Nautilus tank has its own built-in airflow control much like the new Aero Tank from Kanger. You simply spin a little ring to select the size airflow hole you want and it changes the draw on the tank. This affects a few different aspects of the vape...for good and bad. In theory, it should let you tailor your draw to your own preference. In practice, that doesn't work. I'll explain.
So how's it work? Since I wanted to get a good comparison, I loaded it up with a juice that I'm very familiar with (my own DIY Butter Pecan) and have in another of my regular Aspire tanks. The airflow control on it is, well, seriously cool. That said, I have not yet been able to tailor it to my own tastes. Instead, I have been needing to use the airflow to control the pressure in the tank. I did a write-up on my thoughts on the IGO-W a while ago and how I just didn't understand the appeal of the RDA. I hated having that much open airflow. In general, one of the things that I have liked the most about the regular Aspire tanks is that they have a pretty constrictive airflow. I like the flavor that I get from the Aspire tanks. It tends to be pretty dense and rich flavor. The only other technology I've found that gives me as good or better flavor is the cartomizer tank.
So here's my thing. What I didn't like about the IGO-W was that it had no draw at all. It produced massive plumes of vapor, but the flavor on it was almost nonexistent for me. And what I think that I'm finding is this: the looser the airflow, the more vapor production but at the expense of a loss of flavor. That at least, has been my experience. And so we come to the Aspire Nautilus. When the original Aspire head was designed, it had four holes in it for juice to enter the head. Early reviewers complained about massive flooding problems with those heads. Too much pressure plus too many holes led to flooding. So the manufacturer redesigned the head with only two juice holes in it. And it worked well.
The new Aspire Nautilus system uses a new Aspire head design that goes back to the four holes. I saw this in early photos and kind of wondered how that would work. I now know. Even on the smallest air hole setting of the Nautilus tank, the draw is looser than a regular Aspire tank. It needs to be. In order to wick properly and not pull too much juice into the head on any given puff, it needs to have that looser draw. But I set the tank to the tightest setting, which is where I'd prefer it to be, and vaped on it for a while. The flavor was excellent. The draw was good. I was thrilled. And then it started to gurgle and flood.
So I opened the air hole up to its max position and hit my button a few times without tooting at all and it cleared out the flooding. I vaped on it all the way open for a while and it worked like a charm. This morning, I've been vaping with it on about the middle sized airflow hole and it is working consistently well with only the occasional gurgle. It is producing huge amounts of vapor. I mean, I've never had a stock coil produce this much vapor. But the flavor is muted compared to what I get from the regular Aspire tank and coils. What I think I'm finding is that the guys that use RDAs and RBAs with really loose draws must prefer or be used to that more airy flavor.
What's weird though is that the more that I use this, the less that seems to be bothering me. Maybe my tastes are changing? Maybe it's a bad morning for my taste buds, but given that I'm doing a direct comparison of the same juice in both, that's not likely it. But I find myself reaching for the Nautilus tank even though I know I like the flavor better on the regular Aspire. Weird. Maybe it's just the aesthetics of it.
So in the end, I think I'm understanding the appeal here. And I'm beginning to understand something else. The vast majority of reviewers out there are guys that are REALLY into vaping. They are guys who are using rebuildables and sub-ohm setups. So a manufactured tank system with a stock coil that performs a ton like a rebuildable? Yeah, this is going to be exactly the type of system that they are going to fall in love with. I do think this tank is excellent. The one thing that I'd say though is that if you are a vaper who prefers a tight draw, don't assume that you are going to be able to use that airflow control to achieve it. You will more likely be using the airflow to control the wicking in your tank.
If you are a vaper who prefers a thicker e-juice (like a 100% VG juice) this tank will likely work like a charm. I don't have any 100% VG to test in it, but based on how it is wicking my 50/50, I'd bet that you could close off that airflow quite a bit and have a radically satisfying vape on this tank without burning. Again, that's probably an aspect of it that would radically appeal to a more seasoned hobby vaper.
I need more time with this thing to really work out how I feel about it. But my gut is that this is a pretty fantastic tank. I've got a Russian 91% that should arrive to me this week. I'm curious to see if my tastes have changed enough to make me more enamored with this loose draw. I think just maybe, I'm growing up in my own vaping preferences. Time will tell.
