All good bro, appreciate the input, checked a few of them and they are all reading 3.1 lol seems like a bad batch, thanks for explaining the bit about silver outer bits being irrelevant, as that really cleared things up, now i can just concentrate on the inner section....
According to that I straightened out a 2.4 ohm coil from a old kanger clearo and noticed the inner section of my 1.8ohms is about 5mm more longer than the inner section of the 2.4 the grey wire in-between the shiny silver legs so clearly they must be higher ohm....
