I took the PRO out this morning, Temp was in the mid 20's, for about the first hour the VDI jumped all over, ground depth kept reading MAX, and it was a bit noisey. I've huinted this area for years with never a problem. Seemed like when it got a little warmer the PRO worked fine like it should. Just curious if the cold might have had somethiong to do with the way it was working at first. With all thast was going on with it, it still would beep over targets. I just had to listen real good.
