I just recieved this Geyscano 50w bottom feeder mod and I'm still not use to coiling yet, but the mod has an ohm resistance of 0.2ohm---- 1.0ohm, and I was just curious in the mean time as I'm getting use to coiling would I be able to purchase a 0.5ohm sub ohm tank to use in the mean time? and yes it has a 510 thread for 510 atty's
