Just built my first dual coil, set the ohms to 0.3, 24 Gauge Kanthal A1, 6 wraps on each coil. But I have one question, what is the difference if i set my ohms high or low, I'm using the calculator to figure everything out after inputing the ohms, but I'm wondering how to decide weather i should set my ohms to a low range or high range. Thanks guys. First build is going great!
