@@TeamLynchBMD thanks for the compliment. However, I must admit it's nowhere near as awesome as your videos. I was actually looking for whatever was making my machine go beep.
I believe, and this is just my humble feelings about the question you asked, but anyhow, I feel the cover protects the coil and is a good thing. That being said, many detectors don't come with the extra protection and work fine.
