Welcome man. Sounds like you're hooked already. I compare coils to a needy/high maintenance girlfriend. If you talk to her wrong or raise your voice in front of her she will act up. Always reminds me of "Eleanor" in gone in 60 seconds for some reason. "Oh, c'mon don't start with me, no no start start!"

The eikon ems400 is great. The reason you have to set your power supply to rotary mode is a rotary does not have follow through. It i wanting information for the readout which it is not getting so it cuts out. Have fun on the forum. The guys on here are awesome and filled with knowledge.
