My target build is a dual coil .5 ohms for my RDAs. When I use my ohm checker I do get it at .5 ohms. However, when I put it in my VS rDNA 40, it reads the build as .4 ohms. When I put it in my SX Mini it reads it as .6 ohms. It still vapes good no matter what which mod I use. I was just wondering which one is the most accurate reading. I prefer not to go below .5 ohms. Thanks.
