    So I'm seeing a lot of things about dual coil tanks and my understanding is that two coils lower the resistance... Or something like that... Can anyone better explain why I would want to use a dual coil?

    Two coils are used to provide a warmer vape with more vapor production. The trade off is using more juice, draining your batts faster, and occasionally the burnt hit due to the wicks not being able to keep up if you are chain vaping.

    To be honest I've only tried the vivi nova dual coil and they weren't for me. However the iclear 16's perform very well for me and I enjoy them as a sub for my PT2's.

    It's not warmer. A dual coil used in cartomizers is in parallel. That means a 1.5ohm dual coil is two 3ohm coils. This is why you can use dual coils in higher power outputs.

    I typically stay around 9watts with single coil cartomizers, but with dual coils, I can barely use them at 11watts.

    Many others and myself recommend single coils with tanks. I have dual coils, but they're not punched. The extra coil is above the coil in single coils. There isn't a good enough wicking system in cartomizers to keep liquid in equivalent levels on both coils. I do use my non-punched dual cartomizers a lot. I like them with flavors that gunk up bad on single coils in my typical watt range.

    So besides the increased current versus using a single coil cartomizer in double the resistance, you have to use higher power output levels. I started out with 1.5 dual coils, and surprise, I use single 3ohm cartos.

    Edit:I am wondering if some dual coil clearomizers are in series(add the resistance of each coil for resistance of circuit.) The iclear 16 I tried didn't function like a dual carto or RBA.

    Dual coils typically run at lower temperatures than single coils, but they can produce a bit more lung hit at those lower temperatures due to more coil touching liquid to make vapor.

    Dual coils can go through liquid a little faster if you still like to take long slow drags.

    Dual coils can drain your battery a little faster too.

    Yes, sorry you are right. I believe the difference in my experience was bottom coil vs top coil, not dual vs single. Sorry for the misinformation. Still new and learning....

    "Dual coil tank" is a bit of a misnomer, too. The first cartotanks offered by Smoktech were called DCT, or Dual Coil Tanks, and also introduced Smoktech's brand new cartomizers that were...dual coils! Prior to this cartomizers were only single coiled.

    Many novices are not aware that you can use single coil cartomizers in dual coil tanks. :ohmy: In fact, most people prefer single coil cartos over dual coils. Dual coils were a nice idea that never worked out in real life.

    And a DCT is just a cartotank no different than any other cartotank. Same anology as Band Aids vs adhesive bandage, Q Tips vs cotton tip applicator, Kleenex vs facial tissues, etc.

    Dual coils are two heating coils in the carto cylinder, one over the other. I happen to believe that in a cartotank with punched holes, the top coil in a dual coil cartomizer does not get enough juice wicked to it because the wick holes are placed so low on the carto. The end result is the top coil burns the wick material and can often cause a burnt taste. At least this is the reason that I made the switch from dual coil to single coil cartos in my cartotanks.

    DCT tanks are for XL/mega/45mm cartomizers,* forgot to add that in my post.

    I'm not much of a carto tank person. I am a glassomizer person, at the moment, and my question came from the launch of the Kanger Protank 3. I haven't expanded my mind to the concept of cartos and I don't understand what punching holes in a carto would do... Probably create a new juice hole, I suppose. Anyway, with the Kanger Protank 3, you have two four ohm coils to get a two ohm resistance. I'm assuming they would be stacked one atop the other, as well, but I'm thinking the bottom coil of it all would make it so that it would lessen the possibility of the juice not getting to the wick?

    The video doesn't explain squat. It's just some dude sitting in a very noisy background room disassembling and reassembling the tank and then pulling a few vapes on it. He should have shown the coils by pulling the post off the top of the coil assembly. No narration, no explanation; just lots of nothing to be honest.

    Just got done recoiling one.

    My thoughts on my tinkering of duals in RDA and RBA, I don't see anything I can't do with a single ribbon coil other than drain the liquid and battery faster.

    You may be confusing cartotanks with clearomizers.

    The Kanger Protank 3 is a Glass Clearomizer ("Glassomizer").

    I'm not an "over the deep end" vapor chaser, but I do find lots of vapor more satisfying than a heavy throat hit and I can't say enough good things about my iclear16. Love it!
