Embarrassing reminder

Last time at the beach with both CZ's it seemed the CZ6a was not finding many mid-tones although it was cleaning up on the high tones. Quarters were frequent and deep. Thought I had been checking the coil cover frequently and when done, hosed and wiped down the detector. Air tested at home and nickles were only getting about 6 inches. Penny, dime and quarter were reasonable; around 9, 9 and 10 inches respectively. Figured this winter would be tune up time.

Things worked out so that I am going to be able to hit the beach Saturday to get a shot at what Ida uncovered. Was thinking about what detectors to take and decided I wanted the CZ6a along even if not at it's best. Checked batteries (still good, did not change them, only have about two hours on them). Checked connectors and saw sand coming out of the coil cover when I set the CZ6a on it's side. Took off the cover and it was loaded up. Sand must have been wet and sticking up against the coil bottom when I had the cover off checking it at the beach last time. Must not have dried by the time I got home and air tested it with the coil cover still on. Now, few weeks later, it was dry and dumping out lots of ugly gray sand.

With cover off, coil wiped down, not trying to maximize anything, I got an easy 11 inches on a nickle with the 12 inch Sunray coil. Packed her up along with the Sand Shark. I'm ready.

Boy do I feel stupid.

And very happy to have the CZ6a ready for the morning! I don't think I'll put the coil cover on tomorrow.

I used to Silicone my coil covers on to prevent them from getting dirt in them. I took one of my coil covers off to check it out and found it LOADED WITH SAND. Now I have NO COIL covers on Any of my metal detectors.
 
Wow I find that to be strange, I just had to send in a coil for repair as they no longer make Compass detectors. The coil cover came right off will little trouble and there was zero sand or anything else in it. The coil bottom was as white as it was when new, I would have eaten off it! Its been on since June of 1991 steve
 
Buried,
Did you used the Compass around the water?

The CZ6a with the big coil is my go to salt water beach detector if I am not getting into the water. That means the coil gets wet in puddles, ankle deep waves and gets wind blown sand covered too. The water and shallow waves all carry sand and it gets everywhere.

I do not see any significant dirt build up under coil covers after long periods of use when I am just detecting land.

What got me was I thought I had rinsed the coil after coming off the beach ... should have checked more carefully then I wouldn't have been thinking it needed a tune up. My mistake. I have now taken all my coil covers off.

Ya I sure did most of the time I live 1/2mile from the beach. I hunted in the shallow water also. I guess I was lucky. steve
 
This topic of trapped sand, and attaching loose-fitting covers has come up periodically.

In my business, I use a considerable amount of both Silicone and latex caulking.

My thoughts on this are to NOT use silicone for gluing coil covers on.
The silicone caulking products available have significant adhesive properties which might be very difficult to deal with when time does arise to remove a cover, and someone could possibly crack the coil when doing so.

IMO, it might be better to use common painter's latex caulking which comes in tubes, for much cheaper than the silicone.
It will seal just as well, is easier to apply and clean up, and may be removed easier, periodically, because it's adhesion is not as good.

I've been (mostlly beach) hunting with a CZ-20 for many years, and early on, I found he same problem with coil covers. They affected the reliability of target detection with the trapped saltwater/sand, and the covers were a real PITA to remove. I decided that when I wear out a coil, I'll just replace it. Well, mide has seena lot of action, and I haven't worn it out yet. IMHO, forget about coil covers.
 
For various coil(scuff) covers have seen them sell for 8-18 dollars...quite a profit I would say even if they cost a buck or so to manufacture..Unless one hunted in extremely rocky ground doubt if one could wear a hole in a coil even after many years of hunting..Some like them...some don't ought to cover the subject and basically a cosmetic kind of thing and many feel worth the added protection as a new coil coil is quite expensive. They now have a very thin cover that will fit current CZ's which can be easily removed for cleaning, however newer coils must be a tad smaller as these covers will not fit older CZ's...
 
I have always used the ( string type straping tape on my Fisher 1260 coil covers. I use a piece every 90 degree's and it works great, I scrub alot of sand. Did I say Fisher 1260, aka about a 1980 Model. Same detector I will be using at The FMDAC Hunt at Gettysburg,Pa in October-goldnugget-
