Got a used 1000 Ultra off e-bay. Sent it in to Garrett factory for repairs. Got it back and it seems to do OK on the higher conductivity targets (silver and clad), but zinc and below the signals I get sound like popcorn popping instead of a sharp response. I can just barely hear little clicks on zincs, nickles, gold rings and pulltabs. Is this normal or should I send it back to Garrett again?
