so I checked the connection. Sure enough, the coil cord had somehow loosened up, so I unscrewed it a little and re-put it on. The detector immediately started singing. So I guess a loose connection was the problem all along.
Some folks who get new AT Pro machines don't get the coil connector all the way on when they take it out of the box for the first time. I recall you are a bit new to the machine also. The coil connector SEEMS to push in as far as it should and then you screw the ring as far as it will go. BUT...the connector isn't fully seated and the ring never screws down all the way. The water proofing o-ring causes the connector to seem snug before it's really all the way in. Putting a little silicone grease or a bit of saliva on the o-ring will help. Wiggle it gently as you push inward past that first feel of resistance. The ring will screw down a lot further when the connector is fully seated and won't come loose.
Glad you seem to have yours fixed. But do check that you have the connector fully seated or you may have the same issue again in the future.
