Just started with duel coils. I have igo-w and wrapped 2 coils the same way. Tested one by its self and it came out to about 1.5 ohms then put on second one made the same way and tested again and it read .7 ohms or some thing near that. Remade 2 new coils tested both on their own both came out above 3 ohms. Hooked them up and tested again and it came out at 2.2 ohms. It works good but is this normal for duel coils?

I believe dual coils are wired in parallel which effectively halves the combined resistance, so yes, what you're seeing is approximately normal based upon my understanding of dual coil devices. That second set should be closer to 1.5 though, if they were both 3ohm coils..might want to check them individually to be sure.

Yes,, Kellycat is right, so if you want say 2.5 final, you nee to wrap 2 5.0 coils to get it. The closer to identical the two coils are, the better.

Yep. What you dont want is 2 coils in the same atty with different resistances. The closer they are (the exact same being ideal) to each other the more uniformly they will both heat up.

What device are you using them on?

FYI - if you're shooting for two 3.0 ohm coils, you'll want to power them around 4.3 - 5.0 volts (YMMV), because they are 3.0 ohm coils, thus you'll pull up to 3.333 amps. Your device needs to be able to handle that. (The max would be 16.6666 watts needed at 5v)

Dont be afraid of sub ohms...no ones blown themselves up. The igo w is the perfect atty for it. Here in san diego, most shops will drill your holes out, and set u up with a nice .6 or .4 setup and send u on your way...if blowing up was a factor...thered be be all kinds of lawsuits and dead people...havent heard of either. Do tell if you have
