Need help about trying to understand something.

Hi , The other day I took my new metal detector and my old AT-PRO in the back yard to do some comparison tests on different coins and jewelry. I turned on my AT PRO and it just would not stop chattering. I did a ground balance, lowered the sensitivity, checked different channels and still had a problem I had to bring the sensitivity down to 1 so I could use it. O. K., So I thought maybe it was JUST the AT -PRO. I turned on my new detector and it do the same thing So I brought back in the house and stopped.
The next day I took both detectors in the backyard to find out if maybe it would not happen again. Well, both detectors worked perfect even at full sensitivety like nothing happened. I’m just beside myself and can’t figure out why. I know you get EMI and other electrical interference in neighborhoods which does affect your detector, but why one day and nothing another day.
Any feedback would be appreciated.

Any ham operators nearby. Look for antennas on the roof. Out to a mile away. Some of these guys push a thousand watt's or more. Plenty to mess up your detector from a great distance. Look for vehicles with antennas. Mobil operator's.
Here a post I made of EMI and locating it.
That little $25 radio works very well for locating EMI near metal detecting frequencies. Try it.

Military aircraft in the area will do it too.
