Coil covers can be a problem ??

#1 Unread post by robinsenny » Fri Jul 13, 2018 7:56 am

Hi,

I am reading a book on surf and beach hunting (Gold Beneath the Waves), where the author says "do not use coil covers". He says that the salt water and sand will move around inside the coil cover giving unstable and false signals.
He covers the base of his coils with epoxy resin for protection.
Does anyone have any opinions on the truth of this?

Please help.

I didn't find the right solution from the Internet.


Thanks!

It makes sense not to have anything in the way of the coils that can cause a false positive "signal", sand and water has minerals and minerals can cause false positive signals.

I started metal detecting this year in earnest. My friend who has been a big help, uses a coating for his pin pointer and a cover for his coils, and I have followed suit.
Being on the central east coast of Florida, detecting in the salt water is basically a no-no because everything is leased by salvors from the low tide mark out. With that being said, there is a possibility of salt water from wave action on the beach area, so there might be an advantage to epoxy instead of covers. Mine seems to fit so tightly, I don't expect much sand/silt to be sloshing around if it gets dunked.
If the author has a lot of modern experience, I would tend to strongly consider his recommendation. I don't think it will hinder any resale possibility if you explain the reasoning.
Good luck.
Here's one I feel fortunate to have found recently, while learning, about 60' west of the dune in tree roots and scrub.
It came out of the ground this way with only a need to blow it off. No scraping or other cleaning required.
Bronze I believe, with wear visible from being operated. Because of the relative good shape and uneven patina I thought it was modern until I noticed the nail still attached. I still wasn't sure because of modern imitations but I'm pretty sure it is from one of the ships that sunk in the area, possibly 1715.
I still need to do more research on hinge styles from that era.

Interesting, the nail doesn't fit into the hole, so someone was doing something else with this.

Interesting find. I hope to search a fresh water beach here in Tn in the morning before it gets too hot with my Nox 800 and if I'm not having too much pain... hoping to find some Bling.
I'll remove the coil cover and clean if I get to go HH

D, Not sure I understand about the nail not fitting the hole? The bronze(?) nail penetrates the hole and is "peened" over.
The nail is loose in the hole and can rotate fairly easily. The second hole has the metal "peened" over where a second nail had penetrated and been bent over. The wood thickness was about 1/2" judging by how far the head is away from the hinge.
The hinge was definitely cast as seen in the bumpy surface of the metal.
I think this would have been a "T" shaped hinge.
