I've yet to hear from anyone or even hear of many people that can rebuild Atlantis coils with any success and without a major hassle. Tha Kanger OCC coils are a snap to re-wick and rebuild, even easier than the RTA option that it offers. The Atlantis is another beast however. I would love to be able to rebuild them. Can you post pics or a video of your process?
I haven't rebuilt one yet, my wire and coiling tools are in the mail currently, should be here next week. There are plenty of videos on YouTube of rebuilding the Atlantis coil in 2 different ways, one is to redo the vertical coil, which is a bit trickier to get installed but seems to be the best for wicking and reliability. The other is to swap it to a single bottom coil, thread cotton through the air holes and the coil and snip it off. I will probably play around with both builds to see which works better for me.
I would wait on getting a whole new set up. I found the 2 coils that came with my Atlantis were quite harsh, especially at first. But today I put one of my replacement coils in from a 5 pack I bought, and its smooth as silk. MASSIVE difference. Also they may be releasing all cotton coils soon which should get ride of that harshness that I believe comes from the other material they use in there currently. One of my coils was so bad I had to stop vaping for a bit because it was hurting my throat, but this new coil not a cough yet, like night and day. If you want to spend some more money, pick up the Eleaf iStick 30w or 50w, that will give you variability on the wattage which makes a big difference on the Atlantis.
I have 2 atlantis tanks and 2 sub ohm batteries. Love the setup and I'll share my experience with them. Nicotine level definately plays a part in it. I find 3mg to be good. If it sound low just think about it. Your getting bigger hits so youre actually getting more nicotine. Types and brands of juice even at the same nicotine level can be smoother or harsher than others. Sometimes you can get a lousy tasting replacement coil. I do rebuild the coils with japanese organic cotton because of what I saw on you tube. Aspire uses a silica wrap in their coils with the cotton. It flakes off and you end up inhaling it. This has caused great concern to people using the Atlantis tank. I dont want to rebuild them I would rather replace them for the cheap cost but I dont want to take any chances. I'm hoping that Aspire comes out with organic cotton coils without the silica wrap and them I will just replace instead of rebuild. I have been considering the new Kangar tank for this reason. Go on the Aspire website and you can find a few threads about the concern of the material being used. They assure everyone that they are safe but would you trust people that sold toothpaste with anti freeze in it ?
