Dual coil?

[apuck]

Hello all,

I've been using single coiled units forever so that's all I really know, and I've been out of the loop for awhile. I'm looking to switch to a newer style tank though, and am seeing a lot of talk about dual coils. What are the advantages and disadvantages of dual coil vs. single coil? I'm not looking for any information on the whole sub-ohm thing, I have no idea what that is about, and as of right now I have no desire to learn. I typically use a 1.8- 2.4ohm single coil in tanks like the Vivi Nova, and MT3s, and I use these on devices like the VAMO, and eGo styled units. What would I be looking for in terms of dual coil?

Thanks for any information you can give me,

I'll give you what I know...

My Protank 2 uses the single coil heads and my AeroTank mega uses the dual coil head (which my Nautilus can use either the BDC, bottom dual coil, or the BVC, bottom vertical coil) and I've also found that my aerotank mega can use the protank 2 single head coil if I put an extra grommet on the chimney.

As far as difference... Well I can only say with regards to my Aerotank mega since I've used both coils in it.

1. The flavor was absolutely identical using either the single or dual coil heads.
2. The vapor production *appeared* to be a bit better using the dual coil head, although since it was not done in any scientific experiement but rather just from taking a "normal" vape on my tank it could have been that I took a slightly bigger vape using the dual coil, it wasn't enough extra vapor to say "WOW, SO MUCH EXTRA VAPOR", It just appeared to be more vapor with the dual coil.
3. It seems to me that I go through eliquid faster using the dual coil aerotank mega tank than I do with the protank 2 with the single head coil.

I've read everything from "no difference what so ever", to "it's a world of difference, the dual coils are SO much better".

Your mileage may vary.

Aspire Nautilus or Nautilus mini.
BVCs.
Yep.

At the same resistance dual coils will produce more vapor but it will be a cooler vape.

Example:
1 coil - 2 ohms
2 coils - 4 ohms each coil

It took me about an eon to actually begin to notice the difference between dual and single coils. At first there is a bit of a placebo effect, where you will either think it's 'so much of an improvement', or a decrease in performance, but in all reality it's more of a subtle improvement.

Sure, there might be a bit more vapor...but (and I stress, I'm not the most informed person in the world when it comes to this topic) I believe the coils have to work less hard, not having to get as hot to produce the same output that one similar OHM coil would produce. I've experienced a lot less burning and overall nastiness using dual coil over single coil.

Now, if I'm astronomically wrong on this...please correct me.

Now, that interests me. I'm not sure what is going on but lately I'm getting that nasty and harsh burned business going on with my heads. I'm using 2.4ohm heads and am dialed all the way down to 3.0-3.2 volts to try and avoid this. I suppose I might have gotten a bad batch, I've had bad heads before, but not a whole gang of them. This is one of the reasons I'm looking to try something new.

1: dual coils.
A dual coil head contains two coils in parallel, so you're vaping two coils at once;
basically you get twice the fog, burn twice the power, and vape twice the liquid.

Both the new Kanger duel units and Nautilus duel units are pretty awesome. Perhaps get an Aerotank or a Nautilus Mini? (Clones of both can be had preeeeetty cheap)

A dual coil will have roughly 4 times as much surface area then a single coil with the same resistance (assuming they are both the same gauge).
In the case of those stock coils however, it doesn't make a huge difference, because of the way they are cramped and stacked.

If you have the battery power, I would go with dual coil. I can't provide any scientific findings to support that, but when I moved from Kanger single coil tanks to dual coil tanks, I noticed a difference. Vapor production seemed to be better, and the flavor and consistency of each hit was nice. Just make sure you have the batt. power...I hooked up an aspire dual coil to an eGo battery I never use, and the batt. was dead with less than two hours of vaping. It all really comes down to personal preference..Try out stuff! If you don't like it, shelf it or sell it!

This is true, provided your new dual coil set up had an overall resistance of half the original coil; if you switched from a 2.4 ohm single to a 1.2 ohm double. You'll also need to use the same voltage (not wattage) for the single and dual for this to hold up.

I always think of it in reverse though; making the dual coil have the same total resistance as the single. In this case, each coil receives only half as much power. This option would probably affect how gunky your coils get, whereas the "half as much total resistance" duals would probably gunk very similarly to the single, as each coil is receiving the same amount of power as the single.

I will say that a fixed 3.3 volt ego battery had a tough time powering even 1.8ohm duals, in my experience. If you go dual, you'll almost certainly want to lower your total resistance. I have a hard time imagining two 4.8ohm coils would would vape nicely, perhaps even if you maxed the voltage on the Vamo. (Maybe they would, but it seems unlikely to me)

Dual coils ........ not interested .......... end of story
