My sovereign has developed a faint background buzz in silent search. I need to get it checked out. Minelab won't let me talk to customer service. I get the we will call back routine. And they don't. Nor can I get return instructions. I called broken detector and they don't work on sovereigns. It's not a big thing but i want it checked out. If you someone who will do this then send me a reply or pm. I guess they no longer service detectors.
