    Looks to me like you wrapped the coil around the cotton? I don't think that's a good idea. My guess is it will choke the cotton. What you want for these heads is a "Micro Coil"; you install that in the head first, then you pull some cotton through the coil. I use some additional cotton on top of the coil as a "flavor wick" as well. I roll that a little tighter than the stuff I pull through the coil. Also, 3.1 ohms sounds too high. I have a Mini PT2 here that uses essentially the same head; the coil in it is 2.1 ohms (8 or 9 wraps of 30 gauge would around a 1/16" drill bit) and it vapes great with cotton at around 8 watts.

    no i do put the coil in first then thread the cotton through the coil.

    Well, don't give up. Once you get this down, the results are very much worth the effort.

    Wick looks fine IMO. If your coil is 3.1 ohms, I'd say that is your first problem. Not sure what device you're using but if you're only putting out 3.7 volts, I'd say 3.1 ohms is definitely your problem.

    Matter of fact, even at 5 volts, with a 3.1 ohm coil you'd still be only getting around 8 watts. I'd try making a coil with less wraps man.

    Thanks guys! Will keep trying!

    I was guessing the number of coils to do.

    I was using a standard 3.7v battery also have a twist but that only goes to 4.8.

    Is there a number of loops to do to get 2.5ohm?

    There is no easy answer here. It depends on the gauge wire, size of loops, and length of coil legs. I'd recommend taking out 3 loops from the coil in the pics. Then test the ohms on your Seg.

    Of course much of this will be a matter of personal preference, but IMO 2.5 ohms would still be quite high for a 3.7 volt device.

    This might help you with coiling -

    Really?? iv'e always used the pre-coiled heads and there 2.5ohm?

    I still don't understand ohm's and watts!

    No big deal. If that is the set up you enjoy there's not a thing wrong with it. I like a bit more vapor, warmth, and flavor so I tend to enjoy a bit lower resistance if I'm using lower voltage.

    An ohm is simply a unit of resistance. The lower the ohm, the lower the resistance of a coil, therefore the higher the amount of power (watts) that can be produced by the same amount of voltage. Hope that helps.

    To kinda explain watts, think of it this way. Wattage (power) = heat. We need heat to vaporize the e liquid, so generally speaking, the more heat (wattage), the more vapor we get. You can manipulate wattage by 2 ways. If you have a variable voltage device, you can simply crank up the voltage to achieve higher wattage (ultimately higher heat).

    If you are using a fixed voltage device (lets say 3.7 volts), well clearly you can't crank up the voltage, but you can still increase the wattage (heat) by using a coil of lower resistance, which will increase the flow of electrical current, and as a result increase the wattage (heat) . I used wattage/heat/power interchangeably quite a bit here b/c to a vaper, they are essentially the same thing.
