Well, I took the Cibola for a spin yesterday and am quite pleased so far.
A little backtracking.... On New Year's eve I was building a campfire outside (Here in GA, we've had a relatively mild winter so far). I have a lot of wooded areas on my property so I was going all over the place getting limbs and small fallen trees to get the fire going. Once she was a ablaze, I sat down with a beverage (Dale's Pale Ale - if you haven't tried it, go get one now!), looked down at my hand and noticed that my wedding ring was missing.
So began the quest of buying a metal detector.
I have no idea where I lost the ring. So, yesterday I got the detector out in the yard and detected for a number of hours. I found some old barb-wire but no luck on the gold ring yet.
The detector is light enough to swing for hours and feels very comfortable - although, to protect the foam-rubber handle I was thinking about going to a sporting goods shop and getting a leather wrap - you know the kind they use for baseball bats - and wrap it over my foam handle.
Anyways, one thing I don't understand (which may very well be normal) is in the discrimination mode.

you'll see the discrimation level knob in the lower right corner. It starts at Min, goes to Iron, then nickel, tab, and finally to max.
According to the manual, gold and nickel have an overlap in discrimation mode.
However, I find that gold is discrimated out just above the iron setting. I used my wife's ring to test this out so I could make sure I wasn't discriminating out the gold ring I was looking for.
Anyway, that's just something I don't really understand but will continue to experiment.
Personally, I haven't seen where pinpoint is of any real value to me. It gives you a low-to-high pitch beep depending on how close you are to your find. I feel like I can pinpoint just as well by swinging the detector back and forth and zeroing in on the center. Again, that's something I'll experiment with and see if I can find a use for it.
So far, though, I'm quite pleased. I'll be even more pleased once I find my ring.
