I use a multimeter to check my batteries, but I love the convenience of my box ohm checker. I am started to build really low ohm coils and my ohm box from tobeco is kinda kicking the bucket, wild fluctuation on readings, aswell as my nimbus atty threads are too tiny to get a proper reading from it. Price not being an issue what is the best box style ohm meter I can purchase, preferably not from FT.
