After school was out I went to the closest school to try out my"demo" F 70.I attracked 6 young girls.After they watched me dig a few pennies they asked me If "I did this because I needed the money".I was shocked.I said no that this was my hobby.They offered to give me their money.I laughed and politely said no.Long story short,they buried the same clad quarter 4 different times and told me"this is where kids usually lose their money".I dug it up,handed it back and went back to detecting.I found a handful of pennies,a clad dime and a clad quarter.I also found 2 wheaties.It was just great to be outside beeping.
