Since I got my Safari I have noticed I am digging about two inches deeper than I did with my GTI 2500. There are several spots where I found wheaties but never did find silver. I am going back over a couple of these sites to see if the silver is just another 2" deeper. I always heard that if you find wheaties you will find silver, but it has never proven true for me. Maybe now I know why. Will post again when I test out my theory. Onus
