Coil concern - Gold bug 2

[LRC253]

I bought a used gold bug 2 and didn't know too much about it. I used it with the coil cover on and took it off to clean it for the first time and noticed its abnormally spotted and has a few tiny pin holes... I'm assuming this isn't normal but hoping it is. The detector seemed to be working ok. Thoughts??

I would probably fill the holes so water couldn't get in---------------call Kellyco repair and ask them before you do any repairs.

I haven't heard back from them yet, just left a message but what I found odd was my larger coil has an additional bottom that's glued on protecting this black side.

You might want to call Fisher and send them the photos.

It looks like a factory defect but if the pinhole was caused by a bubble that popped during the Resin cure then it would still be waterproof.
The larger looking deeper bubbles around the pinhole might be a defect that Fisher would want to look into.
They can tell by the serial number when the detector was sold new and that sure looks like a factory defect ... not use or abuse.
