I have been in a serious slump this spring. Only a handful of coins and only 3 silvers. Two mercs and a Barber dime. Somehow I managed to turn on the vibrating handle but continued to hunt these last few outings. The machine also seemed a bit unstable,too. I did a factory reset last night and will try to get a few hunts in. I rarely change from Park 1 unless it is to Field 2 due to high emi in the area I am hunting. Sometimes I will slow the recovery speed down to 3 instead of 4 and I always run high sensitivity when I can! Thoughts please? Ted HH!
