First, I hope you're referring to not getting any audio response at all. If you're referring to getting a visual Target ID, forget it. Visual TID will not be accurate to the full audio response depth.

If you're referring to just an audio response, I do have a question or two. Are you referring to checking the performance in the motion Discriminate mode, or did you also check the various targets in the All Metal Prospecting mode? Also, did you Ground Balance for the location at the time of the 'test?'

Odds are you didn't get a good response in that mode, either. because:

8 inches is deep for a coin most of the time my actual response to a target does not exist deeper then 8 inches and I find myself only hearing threshold variations. I relic hunt and have found flats at that depth that barly gave any tone ID but find the same items and bullets up to a depth of 12 by only hearing a change in the threshold. Shoot my oldest coin to date is an 1817 Large cent and it was only at 6 inches. It sounded like a car horn.
