The weather was perfect for detecting in my opinion. The ground was just as soft as could be under the snow We get in the woods turn on the AT PRO start detecting. After about 20 minutes the PRO goes hay wire!!!!! VDI's start bouncing all over and the screen going crazy. depth meter showing MAX. noisy all over, BUT I still can here a target when I go over one. I turn it off for a bit then back on and about a minute later it goes hay wire again. I deal with it and about 15 minutes after that it's working fine! I even went back to the spot it first went hay wire and this time it's working fine. We go to another area of the woods and BAM hay wire again. I detect with the noise and after a bit it settles down and works fine. I almost did a video of it, but figured I could not figure out how to post a video on the web site. I plan on switching out 8.5" X 11" coil from my Gold next week and see what happens. I will take a video next week if it goes hay wire again and I will send it with the detector back to Garrett. I'm statring to get frustrated with it and loosing confidents carrying it all the way in the woods and it NOT working right.. I love the detector when it's working right. I'm trying to keep the FAITH!!!!
