I decided to caulk my NEL Hunter cover on my coil. I was going to use it in sandy creeks etc.. for relic hunting. After doing so, I noticed things were a bit different than before. I looked at the ingredients and it has Titanium Oxide as an ingredient to the black silicone caulk I used.

I caulked a cover on my Sovereign with a Sun 12 inch coil with clear caulk and I couldn't tell the difference. Now I am wondering if I screwed up with this black caulk.

Has anyone noticed a difference when you caulk a cover to keep out water and sand from the cover plate?

Anybody had any problems with caulk?:dontknow:

The reason I wanted to secure my coil cover with caulk was for two reasons. With another NEL coil, the heavy sand and water made the cover come off a few times while hunting in streams. With the amount of black sand in the streams I hunt, it was counter productive to continually unload the sand from the coil cover constantly. Of course black sand causes false signals. Black sand is ferrous.

It might be that the continually taking the cover off to clean it and putting it back on made it easier to come off. I can only theorize on that, but that is what was happening after a while of cleaning the sand out of the cover before & during hunting.

I had the Big Nel coil with another detector. I liked the coil but the sand issue was making the coil heavier than it already was.

This is why I just decided to caulk the darn thing from the beginning with my newer detector. The AT Gold allows me to go under water a bit. I didn't want to lose the darn cover in water that was over a 6 feet deep. I would have to go put the detector on the land, then attempt to dive for the cover. This would be a pain in the butt.

Now, since BZbadger has told me about the bed liner spray, I will never have to worry about the coil cover coming off again or cleaning it at all.

Now the only pain in the butt I have is making sure I get all of this silicone goop off. I will get it off eventually but a death in the family has made family issues a priority since I started cleaning the caulk off. I have spent about six hours cleaning it so far. I have tried those green sided sponges with dawn with no luck. I have used plastic scrapers that just got the big stuff off. Tonight I am doing the Bon-Ami scrubbing to see if this works. I will get it off eventually but, ...again...., this is a major pain in the butt to get it off. The stock sticker glue that showed how to use the coil just moves around but will not come off...... so far.

I am going to put the 5X8 coil on the AT Gold for this weekend. This weekend is the first low humidity/low temperature day we have had to hunt on a weekend with my hunting buddy. I am going to record the College games I want to watch and get at hunting every weekend again starting this weekend. Under 80 degrees is prime weather for hunting down south. The copperheads & pine rattlers will be going away soon along with the high weeds. My buddy and I have been scouting during the hot months and we already have more places to hunt than we might get to during the cooler season down here.

I hope everybody has a great season hunting this Fall, Winter, and Spring. Just don't goop up your coil with silicone. It will just mess with your sensitivity and make a problem that you will regret like I do.

Later eh!.

One Last point, the two NEL coils I have owned need a coil cover. There is just some thin coat of plastic and some paint on the coil. This must be why a coil cover is always included with a NEL coil. In other words, you can't use the coil without some kind of surface to protect the coil.
 

I know the whites coil covers are a pain to remove, I seen a post about sanding part of the lip of the coil cover and it worked great. I only left 2 spots of the lip opposite of each other and took off probably 75% of the lip just test it when you think your close to make sure you don't take to much off as if its too loose it may come off when detecting. I used coarse sand paper and it doesn't take much time or effort, like said warranty and even if you would send it in for repair or replacement(whites usually doesn't charge full price if they can't fix it, they give you a little break on the replacement) they won't need the coil cover.
