Do You Seal Your Coil Cover ?

I have been debating doing that or not. Looking forward to seeing opinions on this.
 
I throw the covers in the trash and I coat the bottom of the coil w/ bed liner spray. I beach hunt and I can't put up with false signals from trapped minerals. Coil covers in the water suck. I had one float away. Unless you are detecting for gold in desert rock I see no need for a cover. As far as resale value goes the coil looks brand new after I coat it again.
 
I have to agree with Goodmore about the bed liner. I hunt inland at parks and playgrounds and at beaches, both fresh and salt water. I can't be bothered with taking the cover off and cleaning out the sand that gets inside. The bed liner works great and its tough. Here's a photo of the one that I use.

Never seal the cover on, you will still get condensation between the cover and coil and have an endless problem with falsing. I seldom hear of someone wearing out a coil from the lack of a cover, especially the newer epoxy sealed coils.

Larry, You bring up an interesting point...my cover isn't sealed, but when I removed it to clean it there was moisture along with the junk. I was getting some falsing and am now wondering if this may have been the problem.

I like the sound of Mat In MA fix and just may remove the covers on my two coils and spray them.
 
I only have one coil with a cover. It's an 11 inch coil it had a flat bottom and straight sides making a sharp edge.I scrub my coil and this one would really tire my arm, especially in green grass.So I bought a cover it had a nice rounded edge.I used black auto silicone sealent to seal the coil and cover. I filled the cover with a layer of sealer and squeezed it on until cover was tight to coil. This pushed out all the air and that solved the moisture problem.That was 8 years ago and this coil is still my go to for large areas . It can be done!
 
Yep, that is why it is important to clean the covers often if you use them. Like Longbone, do what works best for you but sprays, covers and glue is just extra weight for my kind of hunting.
 
Goes to show each look at it differently.... be it resale, depth reduction, or just protection. I have to admit i dont like taking mine on and off..... but i do it everytime before i go out. Im a coil scrapper also... the bottom of my cover is ripped up with gouges. Old habits die hard. NASA Tom talked about an 11 inch coin that with the added air gap and cover made the difference of hearing or not hearing that coin.

I like a coil cover,and it doesn't bother me to remove it to clean it.I don't seal it see no reason to.That nice clean coil and coil cover adds up in resale too.....in facti won't look at a used detector if the coil hasn't be taken care of... but that just me.
 
I don't seal mine, but I do remove them occasionally to make sure there's no crud or moisture trapped inside.

I have tried it with and without covers on various detectors. Other than some minor scuffing and scratches on the bottom of the coil, I have never damaged one and I hunt a lot. I never look at resale value or keeping it looking nice for the next guy. But then I have a tendency to keep things and have never sold a detector :) I do use the cover for the At Pro DD coil since it is pretty easy to get on and off and does have drain holes in the bottom.

Over the years I've been haunting detecting forums, I've read of several instances where coils were ruined due to lack of a cover. If one NEVER scrubs sand or hunts in rocky areas that may not be a concern. As I mentioned in my earlier post, I don't seal mine and do clean them out from time to time. IMHO sealing a cover may lead to a false sense of security as sand and moisture seem to find their way through even the smallest flaw and most wouldn't destroy the seal to check unless they were having a major issue that seemed related to the coil. In the end it's your coil so do what you feel best with.
