Coil Covers – What is Their Value?

Coil Covers – What is Their Value?

When I began metal detecting in early 2008 I, like many who begin in this hobby, had no idea what the value of coil covers were. Due to this ignorance, I hunted without a coil cover for a few years, and my coil took some scratches and scoffs. Although this cosmetic wear in no way effects the coils abilities to detect metal, I have a feeling they may effect my wallet whenever I chose to sell it.

With the above said, over the years I have read about and seen quite a few different ideas for DIY coil covers. Listed below are two that work, and one that did not work out so well.

1. Plexiglass Cutout

The construction of this coil cover is rather simple. Simply trace out the shape of your coil(s) on a sheet of thin (the thinner the better) plexiglass and then cut out the outline. Depending on how detailed you chose to be you can also cutout the opening your coil has, which will also allow you to attach you coil cover to your coil using a few well placed zip ties. Doing so, however, may allow debris to hit the inside edges of your coil, so you may want to instead drill well placed holes through the plexiglass for the zip tie downs.

Two negatives for this type of coil cover is that it does not protect the outer edges of the coil, and when you clean in between the coil and coil cover you need to cut and replace the zip ties.

2. Truck Bed liner

This coil cover DIY method requires only one product. You guessed it, bed liner spray. Oh, and a piece of cardboard to protect your carpet, garage floor, or priceless dining room table. The most important piece of information to remember when considering this method is that the bed liner you use CANNOT contain any metal in its formula. Little bits and pieces of metal on a metal detector’s coil are a big no-no.

Once you have purchased a bed liner spray the next step is to consider how thick you would prefer the bed liner to be on the coil. I strongly advise you to use a test surface before spraying the bed liner onto your coil to check the amount of spray released, how long it takes to coat an area, and your spraying technique.

There is one other potential problem I should mention concerning this method. As one would expect, removing bed liner spray from a coil adds another layer to coil maintenance should you ever need to repair a coated coil. Due to this fact, manufactures who receive coated coils that need repairs may take issue with your work of art. This could, potentially, cause some metal detector manufacturers to add an extra charge to a coil repair bill. I have never heard of a manufacturer doing so, but it is something to keep in mind.

3. The “Sock” Method

Okay, so this method was brought to my attention by a forum member several years back. He claimed that he did not want to spend the small amount of money for a coil cover, so this was what he envisioned would do the same job as a coil cover. Surprisingly, he actually hunted with the sock coil cover. Unsurprisingly, his sock coil cover did not work out as he had planned. As one would expect, the sock picked up twigs, grass clippings, moisture, and probably some of Fido’s doodoo rather quickly. Needless to say, this method is very unpopular.

Final Thoughts

Of course, the simplest way to obtain your own coil cover is to purchase one from a metal detector dealer. Just about every coil manufactured in the last fifteen to twenty years has a coil cover available, and they can be purchased for $5-20 depending on the size and complexity of the coils design.
