I recently baught treasure hunter xj9. this thing beeps at every thing. I sent an email to treasure hunter asking if this unit was defective, or does it act like this. they sent me a reply. If this is a warranty concern please contact your dealer. Apprently they have no one in customer support. stay away from this MD. I can find things with it, but I feel this entry level machine will be verry confusing for beginners and may deter newbies to our great sport. Please spread the word brothers.
