Looks like a 2.5mm clapton. 0.5ohm resistance.
Does yours gurgle and leak? Mine is doing it on and off...
Thanks mate, yes it does it happens on all the berserka minis from what I've heard/seen . It's something to do with the narrow chimney I think I heard. It happens to mine after I've filled it most of the time and need to drag it a few times then it will be okay. I've seen a video on youtube on how to minimize the gurgling but unfortunately I can't remember what the title was.
Also I know they tend to leak just after you fill them up, incase you have had this issue I've found the best way to prevent the leak after filling is placing your finger over the open air hole and have a couple of tapes and it should then be fine.
Unfortunately the gurgling and leaking is a common issue on the berserka mini, if I can find the video I was talking about I'll post it on this
thread. Hope this helps, and thanks for the info on the coil .
