Garrett 250 went crazy

[jamescpittman]

Today I was using my Garrett 250 to locate a steel survey rod buried next to my neighbors front yard. All of sudden my detector went off like I had hit a jackpot at the casino. I mean it was bouncing all over the place with all kinds of different sounds. . I had already reduced sensitivity by two bars, but even raising the meter 3ft off the ground didn't,t help. I reduced the sensitivity to just two bars and it quoted down, but was still jumpy. Is it possible that my neighbor has that much metal in his lawn? We live in a highly populate area near New Orleans. The batteries In the meter were just changed and this was my third hunt since. I've never had this happen. I got the meter for Christmas this year.
Any thoughts, advise, comments?

some one on the garret forum probably could help you more but it sounds like you're getting some type of interference. you could try raising the discrimination to see if that eliminates the problem. you need no disc to locate the survey rod but gradually raising the disc. will show if the noise is outside interference or signals in the ground. good luck
