Running Your Coils Without Covers

[Cupajo]

About the time I answered this post and added the pics of my damaged coil I called Garrett's and spoke to Brad in their customer service dept.

Yesterday received a new coil at no charge and it would have arrived sooner, but they were out of stock.

I closely compared the damaged coil and the new one and in carefully probing the "cracks" found they were surface damage and didn't go as deep as they looked!

I must apologize to Garrett's for my impatience and for not investigating more carefully before I put pics on the net that aren't as bad as they look!!

I do feel that there should have been less scuffing for the short time I had the coil in the water!

Brad assured me that coating Garrett's coils will not void their warranty and that they do get them in coated with all sorts of substances.

Thanks Brad and Garrett's for your prompt and courteous service and your understanding and patience with an old Hunter,

I suppose it depends a lot on how much you scrub the ground or sand to get that extra bit of depth. Myself I tend to keep the coil slightly off the ground for the most part. I have gone without covers on some detectors without problem. On my At Pro, the dealer included the coil cover so I use it. I have seen a lot of pictures of damaged coils on various forums over the years and I just cannot relate to how hard the coil had to be banged to crack it. Scratches yes, I think they are part of using the detector, large cracks with chunks missing are something else. Like everything else, it is up to what the individual preferences are.

After doing a lot of research and reading many posts on the subject, I decided to spray both my coils with "3 M Professional Grade Rubberized Undercoating". Wow, I wish I had done this sooner. I have no interference what so ever, and I don't have to remove the covers to clean them anymore.

I sprayed on two coats and it's more than enough protection. I'll keep an eye on the bottom, and if/when I wear through I'll just spray that area again. One can will easily do multiple coils.
