Well thought I would improve I hope a dual coil and save some Non Resistance wire here is what I did (With reading glasses on) Two resistance wires attached to two non resistance wires one on each end ohm'd out to .6 - .7 ohms Works great in my ody old 3.7v bat and 2mm silica wick empty one on the bottom and coiled one on top. Just to save non resistance wire (On a wife budget)



simple and easy for me
