Temps in Mn were in the low to mid 50's for the most part, but had some nasty 15-30 mph winds to deal with wind chill wise and fishing. My son and I fished much more then I detected, but I did get in 3 couple hour hunts each and the Omega did sniff out some more silver and 2 wheats and 2 buffalo nickels plus a little under $3.00 in clad and some junk jewelry. All finds came from an old fairgrounds. The 62 Rosie was with in an inch of a rusty nail and some of the rust leached onto the dime. The no date buffalo and 29s Merc were in the same hole. The other Merc is a 1919 and then on my last hunt on the old grounds got the 1903 Barber dime and the 52 wheat. HH jim tn
