Yes! dual can be used on mech mod. why not?
Hmm let me try to put this into picture, hopefully you'll see it with much better understandings.
3.7v IMR Batteries = Voltage Current (
imagine this as 1-way water current)
Coil = Carrier. "Straw / Water pipe" (
now imagine this pipe get plunged and start drawing from the water current)
Ohm/Resistance = The results aftermath (ie.
the smaller the diameter of the pipe, the greater the resistance is experienced from current to gush through and vice versa)
Single coil > 1 Straw/Pipe
Dual > 2 Straws/ Pipes
Quad >so on n so forth..
If you'd get the drift, setting up dual coil will force the nature of the current to go into split channels. With that in place, dual setup results in much lower ohm readings/resistance due to the split. But, more current is required to push through to meet both ends. In another words, what you get is simply both the wicks evaporating juices at the same time, thus double the taste/vape. But, battery will be drained out in a much much faster rate.
Highly doubt one could get 3ohm on a dual. Unless super high 35-40gauge wire and ridiculously lotsa rounds this coil is clocking.
PS: always use a ohm reader to test the atty/carto before sucking on them! and duncha follow blindly on the table. its like a parental guidance thingy. lol
