5x10" DD cover falls off

The usual solution is to run some black duct tape around the coil's rim. This prevents the coil cover from dropping off if you crack it and it keeps magnetic soil from gathering between the coil and the skid plate. Every once in a while you can remove the tape and clean the skid plate.

Hi
The 10 x 5 has a design fault in that it is not flat
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
have a look at it from its side, easyer to see if yoy look at the top edge.
Thats why they dont stay on

I took a look at mine and it appears to be flat. Not sure what you are referring to, I guess. But I agree, it doesn't fit as tightly as most other coil/cover combinations I have. I think if the elliptical cover were just simply made a bit smaller, for a tighter fit, it would help. Most other coil covers are allowed to go to the top surface of the coil. Or, the covers have a little lip that secures on the coil. This one is not only a smooth surface, without a lip, but the rim at the top of the coil doesn't allow it to wrap over or even go to the top surface. It just slips on, without sufficient friction to hold it in place. I suppose some would argue that being able to take it off quickly, to clear sand or dirt, is a positive. And some would prefer to not use a coil cover. Personally, I always use the cover. But I wrap a couple wraps of black vinyl electrical tape around the "seam". (I don't water hunt) It keeps the dirt and debris out from between the coil and cover. And, it easy to peel off and replace, should I chose to do so. Much less time consuming than removing an old layer of silicon, cleaning and replacing the silicon. Like I said, I don't water hunt. HH Randy

I think that not using tape is worse that using it because the loose fit of the scuff cover means that magnetic or iron based sands can get trapped between the coil and the cover and when these shift, they trigger a false reading from the detector and plenty of noise. When I first bought my X-Terra 70, the salesman who sold it to me was also a Prospector and he insisted that I run electrical tape around the outside. Even if a foil-backed tape was used (probably not ideal), it shouldn't cause a false signal because the tape, just like the coil cable, is static and should not move. The X-Terra 70 requires movement from the target in relation to the coil in order to trigger a response.
But it wasn't the risk of dust which caused me to tape up my coil: It was another issue which the Prospector warned me about. He said that when you're prospecting in the bush, you tend to bash your coil up against rocks, especially when you take your eye off the coil when detecting. After a while, this can cause a split in the coil cover. You probably don't want to be scratching up the underside without a cover to protect it from sharp rocks. Any splits in the plastic cover causes the cover to fall off easily and nothing will annoy you much more than this when you want to be detecting. He said that even if you split your scuff cover, the tape will hold it in place.
I haven't split my cover yet but I have certainly given the detector a heck of a ride when I go out. The tape has kept the gap between the cover and the actual coil VERY clean and I just need to sponge the coil with a moist cloth at the end of the day to revert it back to it's original state after removing any dirt.

I must admit that my 10x5 coil cover was pretty dodgy and a pathetic fit. To make it fit I put it on the coil, both ends with a big gap, squirted some clear silastic around the edges, then had to place wood over each end(toe and heel) then put a full brick on each end of the wood to close the gaps between the cover and coil and leave it like that for 4 hours till the silastic had done its job and dried out. Been on for 4 months now and has stayed well and truly put.
