Maybe this shouldn't have been my first detector ever to get. (but I couldnt pass up the price used) I am a newbie, started late last fall and have finally stopped digging up nails but now I am digging more soda twist caps from the 70's than anything else. I have been doing parks and fairgrounds and have found about $20.00 in clad. I believe the oldest is 1978. yee haaa. Wish there was someone in Northern NH to give me some 1 on 1 help. Yesterday I spent 6 hours in a park covering about a 20ft X 60ft area. I got 10 nickle hits which were pieces of metal yogurt covers and 32 pennies. I am ground balancing and running everything on the red numbers that are recommended. some tips for a newbie would be great.. Cant wait to find something older than me. heading out again on the 4th to finish the park.. thanks..steve
