Got out to a small park with a tennis court and tot lot. The tot-lot produced one nickel, however the grassy hills surrounding the tot-lot produced the rest of the coins. Even with the current glitches, it is still useable. You just have to give it a 3-4 second rest occasionally when it retains a strong signal from a previous target. I found a couple of coin spills where the audio stopped abruptly, and each time I checked the spot with my pin-pointer, it sounded off in multiple places validating that there was more then one coin. Good information to know at this point. I am hoping that the glitches get fixed this coming week.
