I have the se pro...when I am hunting in the IM mode and I detect a target and push the pin point to center it, and push the pin point off, lay the detector down to dig the target and when I get up and start to swing the metal detector its really unstable. Sometimes it goes away on its own after a few swings and sometimes I have to push the detect button to fer-con. and back to IM before it becomes stable...is that just the machine or could there be a problem with it....
