a 1.8 ohm dual coil contains two 3.6 ohm coils.
if the ohm jumps from 1.8 to 3.6, chances are one of the coils is not firing.
yes the old tank will work on the istick; just start low watts and move up slowly.
if you put too much power it will burn out the coil, (and cough a lot)
oh wait; if its the mini protank, that uses ego thread; you will need to use the 510/ego adapter that ought to come with the istick.
