Ok. So I went out for about 45 minutes this evening. I only have had two short hunts under my belt since I got it for Christmas. Found a few coins and a bunch of trash. I have had an issue with the ATPro that I can't figure out. Here is the deal: twice when I have turned the machine on it seems to be going haywire. The screen with the numbers and the beeping tones are going crazy. I was not around any steel equipment, power lines, or anything else that would cause this. I would turn the machine off and then back on and it would still do it whether the coil was pointed to the ground or the sky. Visually and audibly the detector seemed like what a super computer would do making a billion calculations per second. Both times to get it to stop this I would completely diconnect the coil wire from the MD and plug it back in. I am sure the plug ins were all connected well to begin with and am not confident that unplugging it and then re plugging it in actually solved the problem or if it was just a coincidence. Anyone else have their Pro go haywire for short bursts of time?
