I tried a dual coil build and it just isn't working for me. I tried using it with that new bakero flat ribbon wire but it was just kinda tough since the igo-l doesn't have holes in the post that I can push the wire through. I'd get it all wrapped up and tightened down but the coils would not fire or sometimes only the part coming off the positive post would light up. I was probably shorting it out somewhere along the way..
Long story short, I gave up on the bakero build and just used some 28 gauge A1 kanthal. It didn't seem to work either. Sometimes, one coil seemed to be brighter than the opposite one. Sometimes I'd get 3 out of the 4 coils on each side to light up. I poked and prodded, moving it around with no success. I thought this device would be easier to work with than my smok rda but so far, no luck. Been looking for a good quality daul coil build tutorial for the igo-l on YouTube but I haven't found one.
