Well if you call 3in of snow good lol but it was not frozen.The site was loaded with iron and I was tring to run pretty hot 28 manual it seemed ok but noisy so I tried auto +3 then it seemed to separate the iron better is that right and how much depth do I lose in auto. By the way I think I am going to love my E-trac only found a 1953 nickel and 2 wheates 1912 and 17 but one was with a big nail thumbsup01 .
