Can you wear thru coil?

[vietvet]

All this talk lately with protecting the coil with cover,epoxy, or bed liner. Was just curious if any one has ever worn thru a coil with out any protection?

not me personally,but i did meet a guy out in a field one day that had a whites 5.3 inch coil with a major hole in the bottom...he said it didnt affect performance and he had no plans to fix it either..... i have a 9.5 coil on my 5900 that has seen alot of action ....i never had a cover for it ....it showed signs of heavy wear so i coated the bottom of it with 2 coats of pvc glue and let dry on the radiater overnight between coats....seems as hard as the rest of the coil ,so i think it will hold up well....i tried bedliner on one of my other coils and was not to impressed--very messy..it was strong but also left a coarse texture which is hard to move when coil is touching the ground....

I've read of several instances. Seems to happen occasionaly with those that rub the surface of the sand when beach hunting a lot or similar. While I agree that the modern detectors don't need to literally scrub the ground, I do believe depth is lost if one doesn't swing close. I, personally, detect enough rough areas that I prefer to use a coil cover even though I may never prove the need.

I would say the hollow box coils would be pretty easy to wear a hole through the thin plastic bottom, but the poxy/resin filled ones would be more difficult to wear it out, if possible at all.

That is, NOT if you use the search coil in the manufacturer's suggested coil-to-ground position, or if you're simply sweeping on top of the grass, or only occasionally bumping into the ground.

I have, back in the 1970's and early 1980's, seen a couple of very avid California Beach Hunters who had eventually worn through the bottom of their search coils. Back then, the makes and models used performed well if they DID maintain contact with the ground to eliminate falsing from raising or lowering the coil from a hunt position, and also because they these people were on the beaches almost every day, and sometimes all day. That was a lot of serious wear-and-tear due to the abrasive beach sand.

Then, too, while I am not a component maker I do wonder about the ruggedness or durability of the coil material used back then compared with what is used today (by major manufacturers)?

Next month, March, I start my 48th year enjoying this great sport, and I am not and never have been a 'part-time' hobbyist. I get out often, a lot, and I try to hunt as hard as I can. In these modern times I bump the ground, sure, but try to work my coils about

I have a retired friend who metal detects FULL TIME year around ( he goes south in the winter time ) and he has worn through the bottom of one or two of his white's coils so far and I personally saw the last one. You could actually see the copper wires showing thru and the amazing thing was he said the coil was still working right up until he replaced it. You do have to understand just how much this guy coin shoots as he has been averaging over $2,000 a year in coins for at least each of the past 5 yrs.( $2,500+ in 2009 and 2010), I too didn't think it was possible to wear thru the bottom of a coil until seeing his.

i wore one out once. i didn't know it until i hunted one morning before the dew had dried and started getting a lot of false signals. a coil cover keep the moisture off the wires and i could still use the coil.
