This may sound like a simple question but it's something I'm really curious about.--Do you use coil covers on the coils for your XL PRO & IDX Pro?---I'm well aware of the pros & cons of coil covers (or lack of them) but was just curious as to which way you preferred.-------Thanks, Del

I WON'T use them...Too much dang trouble to clean em, and I think they take at least an inch off of depth...Only way I DO use them is if they came with the coil I bought, and I cannot get the sucka off...like on my 8" for the White's Classic I own...someone musta stupid glued the darn thing on...
HH,
HH,
As a rule, I do not use them with the exception of on the smallest coils, such as White's 4" Snooper (Blue Max 350) or a 5" Excelerator.
Why DO I use them on these coils? Because these coils are small and lightweight even with the coil cover installed, and because these little 'tools' are able to be worked in and around dense brush and building rubble, rocks, and other tight places.
Do I NEED them on these smaller coil? No, but as I mentioned there's no felt weight or imbalance with them.
Is there anything I do NOT like about using coil covers on smaller coils? Yes. Even without any small, gritty dust or dirt to help bind the coil cover they can be a real pain in the arse to remove. However, since I keep my detectors clean from outing to outing I seldom remove the coil cover as it isn't really needed.
Why DON'T I use a coil cover most of the time? It's because even though they don't appear to be very heavy, the felt weight when out on the working end of the rod can be a bit fatiguing, especially for some women and young folks as well as those of us who are getting a little older. I know I can get longer detecting times in w/o a coil cover as my arm/shoulder/back can tell the difference.
All anyone has to do to see if there is a difference for them is search for 30 minutes with a coil cover attached to their favorite coil then stop, removed the coil cover, and get back to detecting. If you can't tell the difference then you're in the minority. Most are surprised at the pronounced reduction in felt weight.
Another reason I don't use them. Manufacturers didn't use to offer them or really promote them very much. In the earlier days of TR and TR-Disc. model use, or when the VLF/TR-Disc. models came out, it was very important to maintain a consistent coil-to-ground relationship unless in the ground balanced VLF (GEB Norm) mode. One easy way to do that was to work the coil right on the ground. The technique of "scrubbing" the coil was especially promoted in the late '70s into the early '80s for those using the VLF/TR-Disc. models Usually, this was a technique employed by "Coin Hunters", and typically such searching was done in grassy areas. Thus, no real wear-and-tear on the search coil.
I know this is a White's Forum but let me mention a Tesoro factory comment about coil covers. When Tesoro brought out the 'spoked' or 'spider' coils they had the exposed epoxy on the bottom and many wanted a coil cover to protect the surface look. They put out a statement to dealers that there was a slowness in the production and availability of coils because they had to step up coil cover production. Almost everyone wanted a coil cover for their new spoked coil, whereas for twenty some years Tesoro only had a coil cover production equal to about 50% of the number of solid search coils they made. Why? They were not needed or desired.
Since most TR-Discriminate production ended almost a quarter of a century ago by all the major manufacturers, we have been able to enjoy units that feature ground compensation. The GEB Norm. and GEB-Disc. (motion) operating modes are the most used in the industry, and if you read almost every manufacturer's Operating Manual they suggest you work the search coil "an inch or two" off the ground. This helps eliminate drag or hang-up and promotes a smooth, consistent sweep of the coil. Also, it can eliminate some "overload" responses from the shallower targets, and even more important it can provide better all around performance, especially in more mineralized ground, as there can be some issues of "fold-over" when a search coil is positioned too close to the ground. This is especially true with many of today's high gain models with bigger coils that 'see' more ground and are therefore more reactive to it.
Usually, my search coil is worked along the grass tops and over bare ground I guess I'm generally about

Monte----Lengthy reply (no problem)!--Interesting (YES, VERY INTERESTING).---Hadn't heard that about the Tesoro coi/coil cover history before.---I'm an old fogey that has always insisted on coil covers on my coils.--There's been plenty of times when I had a few choice words for them, come cleaning time (removal). I'm going to try your coil cover/no coil cover test on an actual hunt (interesting).---Sounds like you must have a modified shaft & adjustment for the coil to swing fairly close to your feet to have the coil "clear" the ground 1/2 to 1 inch (especially with the heavier coils)?---I have ALWAYS had a concern about mineralized sand/dirt getting between the coil & coil cover but have had the idea of wanting to "protect" the bottom of the coil.--I surely do like the idea of no coil cover.---How about the use of a (non metallic) pickup bed liner spray applied to the bottom of the coil (for added durability)?---I have tried that with a couple of my coils and it SEEMED to work well.--Your thoughts on that?----Sorry for my long post! 
----------Del
----------DelIf you are a person who likes to buy coils and sell them later use a cover. Protecting the bottom from scratches brings top dollar. Showing a picture of the bottom of the coil helps sell them. If you are going to keep that coil there is no reason to use a cover. I have never ruined a coil from not using one.
- - is spray on truck bed liner. This is a trick used by many beach hunters. A couple of thick coats and the bottom and sides of the coil is nearly impervious to anything out there. If it does get nicked or chipped, a little touch up is all that is needed. And no dirt or sand can get inside to cause havoc later. I reckon if it is good enough for 'surf pirates', it is certainly good enough for me.
Some complain about warranties with this, but I haven't bought a new detector or coil in years. I haven't seen a warranty around here in a long time..... hell, I wouldn't know one if it bit me on the backside!
So it isn't an issue. I just keep the spray away from the join seam, so the coil can be opened if needed.
But like Monte says, coils aren't fragile. They live and work in a tough world. Most people know this, and few scoff at the lack of a coil cover when they learn that I actually USE my detectors. They know up front that I did what I could to protect it, that it is functional and I am not selling any detector of mine in "mint condition...."
Full disclosure makes up for a multitude of worries. Yeah, baby!
But, if coil covers make you happy, well... it can't hurt to have one.
P.S. As for depth performance, 1/16" or less worth of plastic cover stuck to the bottom of the coil aint gonna make a difference.
Sorry, but there it is.

Using a protective spray coating would certainly eliminate the dirt that accumulates between the cover and the coil itself, but doesn't provide the reduced weight benefit of being 'coil cover free'. Has anybody done a weight before and after test on their coil when putting on Rhino Liner?
Good luck,

The bed liner adds no weight you can tell. Of course it adds something, but the stuff in the spray can is really just a very thick paint. 2-3 layers add an insignficant amount of weight.Rich (Utah) said:
But now Im curious - is there a reason why the tiny bit of weight from any coil protection scheme matters?
I've never found it to be noticable....
I am all for light weight out on the end of the search coil. It is all about leverage. The more weight I get out there on the end of the search rod, the more sore my arm and shoulder are when I call it a day; or they make me call it a day.
I can't say that I am too enthused about using a coil without some sort of cosmetic protection. Some keep their detectors on the truck seat next to them in a protective bag, others don't mind letting it ride in the back of the truck with the camping gear. Regardless, if I'm buying a detector that appears it wasn't very well cared for, I am likely to keep on looking or at least offer significantly less. Detector coils are $150 and up.
I do reserve the right to change my mind. I am getting older and the muscles tire more quickly and the bones ache when I wake up in the morning after hard work, It may be that removing an ounce from here or there may help and I will get to the point that I don't really care if the coil gets scraped up. But for the moment, I"m not quite there yet.
Good luck to all of your. Keep the coils swinging.
