One more opinion, this one from out in left field. And that is:
I don't like coil covers.
I've been detecting for 35 years and I have yet to come anywhere near wearing through a coil. If I ever do wear through a coil, the detector will be so old as to be obsolete anyway.
Granted, I don't hunt in rocks or wet sand. Those surfaces would probably be more harmful to my coil than the grass and woodchips I usually hunt.
Three reasons I don't like coil covers:
1. Gunk gets in them. Some coil covers are difficult to remove to clean. If they are easy to remove, they pick up gunk easier.
2. They add weight to the detector. I'm a wimp and don't want extra weight.
3. They reduce your effective depth. Not by much - just by the thickness of the cover - but that extra 1/8 of an inch may make a difference on a gold ring.
Guess I could add a number 4: They cost money. I want to FIND money, not spend money.
Picky picky picky?
Yep.
Maybe that's why I have a hard time keeping friends.
