The manual says park one for coins. But Im reading from some folks that Park 2 for coins is the way to go. Thoughts? Also, anybody come up with a list of settings that will best enable this detector to find coins other detectors miss. Haven't found anything with the 800 in an area pounded by my ctx, that produced good finds in the past. Thought for sure it would unmask more goodies. I'm guessing some of it is lack of experience with the detector.
