Well, I finally got my Vapor Shark 0.3 ohm ni200 coils for the Nautilus the other day. My initial results were good on the first coil with airflow set to max, just starting out at 10J and 370F. The coil read at about a 0.53 ohm resistance instead of 0.3 ohms when I first locked the resistance in on the D2, but I've come to expect that. I've had similar differences with other stock nickel coils - though all of them eventually failed. I didn't end up raising the max temp all that much and was getting good mouth-to-lung hits at about 11.5 joules. I had some gurgling with the Mini Nautilus at first, so I tried a few standard techniques to clear that up, including slowly re-thickening the
juice blend I was using at the time. That, combined with raising the joules a bit, helped quite a bit. The MTL vape was good, then...
Yeah, fairly similar results as I had with the much cheaper Vape Only vAir-T 0.3 ohm ni200 Nautilus coils...suddenly the coil stopped working. The active resistence readout on the D2 display jumped just over 1.03 ohms - when previously I'd pretty consistently been hanging around 0.83 ohms with this coil. Then I got the dreaded "CHECK ATOMIZER" warning and the ohms readout was showing 0.00 ohms. I tried taking the tank off, took it apart, cleaned the contacts, re-tightened everything together, then snugged the tank back on the D2 nice and tight, and locked the coil in at about 0.8 ohms. But still nothing when I tried to fire it up, except the same "CHECK ATOMIZER" and 0.00 ohms displayed as before. I tried this several times.
Then I gave up on that Vapor Shark coil and instead tried another one from the same blister pack. This time when I tried to lock the coil I got a 0.8 or so ohms reading, and then the dreaded "CHECK ATOMIZER/0.00 ohms" displayed before I got any vapor at all. Even after I had reset back to the earlier lower settings I'd initially successfully used for the first coil before it gave up. Re-tightening the new coil assembly in the tank base, then re-tightening that into the D2 didn't change my results. Now very frustrated, I threw a regular Aspire 1.8 ohm stock BVC in, showing 1.93 ohms in regular Power Mode, and am running fine for hours and a day now at around 11.5 watts. I can now see how the extra airflow availble with one of those Beyond Vape Silo
tanks could really help provide a cooler high vapor MTL vape from the stock kanthal Aspire BVC heads.
What the heck? Are these nickel Vapor Shark Nautilus coils just as crappy as the nickel Vape Only Nautilus ones? I thought Vapor Shark coils were supposed to be pretty good? They certainly are priced like they should be! Or are they both just fine, but there is something crappy about my particular IPV D2, or just the device's design in general? This TC stuff so far has been extraordinarily frustrating. I'm getting a decent MTL vape using the stock kanthal 1.8 ohm Nautilus BVC head on the D2, but not as good as I was getting when the first Vapor Shark nickel coil was working properly (even if only for about an hour). I will, of course, eventually try the remaining Vapor Shark coils I have. But before I do, I was wondering if anyone had any further suggestions as to what I might try to improve my results? Right now I'm about ready to tell temperature control it can kiss my behind unless it can start reliably performing like it is supposed to.
