Lori,where did you hunt at? Location could be the key to your problem.Don't worry,better finds are bound to come,sooner or later.I read that your using a White's Prism V.I am not familiar with that machine or i'd try to offer some advice.Did you watch the instruction video OVER AND OVER?
What kind of detector did you use? I found two pouches of Junk to my $1.33 in coins. about three hours or so. I've been at it for a few weeks now and learn more about my machine everytime I go out. Don't get discouraged.
LOL but, I saved every scrape of aluminun I found and tossed it in a trash can. My wife made me get rid of it and I sold it to the scrap yard for 80 bucks. To make long story short, I took her out to eat with the money. The aluminun bin stays, she said.
