......my advice don't bother with coil covers....period. I've used a huge variety ofdetectors, since 1974 and the coil cover is simply a waste of money and causes lots of problems. Go ahead and use your coil as it is....I've yet to wear out a coil through use...unless you actually are "scrubbing' the ground which with today's detectors would be simply foolish. My frined has been usuing the orginal Sovereign since it came out with the original coil, he's retired and hunts at least 30 hours a week... it will take him another ten years to wear out his coil. Coil plastic is tough and coil covers in my opinoin are simply " add on profit" for the dealers!!!
