I was wondering what type of change's that most of the guys that have been having success have been making other then changing from the DD coil. I can't seem to get no more then 4" to 5" of depth out of both of my V3's. I'm not able to get the V to settle down it want to false a lot and very noisy been working mostly with the sensitivity,discrimination and all metal (very little) I've also played with ground filter.
