Well I took care of the coil cover problem. I have removed it a couple times to check it out and was surprised at the amount of water ( which turned the dirt to mud ) that was behind it both times. I have used it in wet grass, but also rinse it when I get home. Keep in mind that I have only been detecting a short time so I can't imagine people that have been doing it a long time and never remove the cover to clean it.
Being the cover is to protect the wear on the coil and nothing more , I drilled a single, 3/8" hole in the heel of the cover. Now, when I set it down, the water that may have gotten behind the cover can easily drain out. This is not a substitute for removing the cover occasionally for cleaning but at least I don't have to worry about the water staying in there any more.
