Dave J had seen my post concerning my loosing the coil plug screw on my 10" coil for my Omega, which in turn caused it to become very erratic as it wouldn't always make good contact, and pm'ed me that he would "take care of it" and have replacement screws sent to me. Of which, he did and I got them Fed X yesterday via Hector. I never even had to make a phone call. Pretty grand service in my opinion. Although I had robbed the missing screw from another coil, I hadn't used the 10" coil until this morning and promptly dug a 55 Washington quarter at 6." I say promptly, but in our bone dry, hard as concrete dirt, it took me a good ten minutes before I saw the reeded edge of the coin down in the bottom of the hole. I almost gave up on it. As a fairly new Omega user, I continue to be amazed on how well this detector locks on coins. 92 vdi with no bouncing numbers. Oh, 99 sen. 1 disc., 3d tones and gb of 72-77. Again, thanks guys.
