Got out today in 20 degree temps(wind chill around 10). The only find of the day was a 1920 Wheatie then the PRO started acting up again. VDI flashing wild, depth meter maxing out and could not ground balance. Just like before I thought it was the coil and swapped it out with my other one. I change batteries, turned off my cell phone, etc. This time I made a video of the problem in action and I will send the SD card in with the detector. I would post the video, but I just don't know how. I don't even know how to shrink it to e-mail it to Garrett. I one of those computer illiterate kind of guy's. Here are some photos of the out doors at least. I did find a candle wick holder and a bottle with a funny screw cap with spout on top. I'll keep you all posted.
