Could be that you have to locate it anyway - learn from your machine.I have a Black Max detector and sometimes it doesn't beep but I get a reading on my dial why is this?
Could this been an object to deep ?
Turn your descrimination down a tad bit. Sounds like you're right on the edge. Dig the target then remember it for the next timeCould be that you have to locate it anyway - learn from your machine.
Is your "Discrimination" setting up some.? If so, set it to Zero
Try "All Metal" mode and jack up your Sensitivity more.
Good Luck and
