Someone said there is no dumb question...

[sonnydigs]

So I hope this isn't the first one..
I see everyone getting coil covers or spraying the coil with bedliner..
Would someone tell me why it's needed..
If you do spray a coil, is there a particular color preferred??
Really not sure why it's needed, (but if it's the thing to do, then I will) so if anyone can explain it I would certainly appreciate it..
Thanks

It basically just protects the coil, and the wire windings with are embedded in a tough resin inside. Hunting in areas with sand and or rocks can wear down a coil, especially if you hunt often. Although the coil damage is rare from metal detecting, getting a coil cover is cheap insurance for a long lasting coil.

 

[sonnydigs]

Thanks John, and what is your preference??

 

[John-Edmonton]

I use coil covers on my favorite coils which get used the most.

 

[sonnydigs]

Thanks John, I suppose it is good insurance so I will put that on my list..

Do be aware that some bedliner sprays contain metal particles as part of the formula. So I would check with mfg of product(s) you are considering using.

Thanks for the tip, I'll probably just stick with the cover..

[size=large]first off the credit for the saying of no dumb question goes to my drill instructor while in boot camp some 40 yrs. ago.
second be advised that dirt or sand can work it's way inside the coil covers and will cause falsing. so they do need to be cleaned out from time to time.

Hey, I had one of those drill instructors too! Of course he said lots of other things not printable here as well. I can vouch for Dupli Color bed liner working well and not containing metal.

Thanks Sailorman,
I do like the concept of spraying it..
Any prep work required??
Any problem with peeling off??

 

[Sailorman]

Most coils are potted with epoxy potting compound so there is usually a little amine blush on the surface. It's water soluble and a scrubbing with a new, uncontaminated, scotch brite pad with a little dish soap will remove it. I followed up with a quick rough up with some 120 sand paper to give the bottom a little "tooth". Just a light go over of the bottom.

Taped off the sides and wire with some blue masking tape. Did a final wipe down with alcohol (not rubbing alcohol) on a new rag then put on four LIGHT coats of the liner. It takes forever to cure if you put it on heavy. I learned that lesson on my first coil! It may not cover completely on the first coat. It sprays out in pretty rough coats. But the subsequent coats will cover it.

Let the whole job cure a few days if you can before taking it out. I have worn through the job on my Pro Pointer and will be recoating it soon. The coils are fine and holding up well. No peeling. If it does scuff through it's easy to recoat.

 

[sonnydigs]

Thanks, are you saying don't paint the sides or the top??
If so I thought it was the sides at the top of the coil that are susceptible to leaking..
I guess I'm just confused as to what all gets the paint..

 

[Sailorman]

Coil covers only cover the bottom of the coil. That's where the slot is that holds the coil wire and the potting compound. The wear tends to come as your drag the coil over the ground or hit gravel, rocks etc.

So therefore one normally only covers the bottom of the coil with the bedliner. Nothing keeping someone from coating the rest but it would just add some weight without much benefit.

Thanks for all the replies..
Appreciate them all..

I always remember that gentle wake up call that first morning as two drill sergeants bellowing at the top of their considerable lung power kicked steel trash cans down the passageway between the racks turning over the ones of any slackers slow to get up. Yup, this wasn't their mommy bringin' hot chocolate!

Well you've done it now, I'll be having nightmares... :-(((

Gotta love the steel trashcans rolling down the bay with the security baton banging on it. And you better spring outta that bunk quick and have it square'd away in a couple minutes. I just slept on top of the blanket. Joined the Navy.....got sent to Uncle Sam's Misguided Children after boot/school. Took good care of my guys. And they definitely took care of me. Semper Fi.
