Words can not express how happy I am to have Kirby as my friend. We use to work together in the state penitentiary as officers. Word got out that I metal detect and Marvin started asking me more and more question about the hobby. What is a good detector to start off with and so on. We started hitting the beaches and the parks in our area. The next thing I knew he was making some great finds. From what I understand he doesn't charge anything but he does ask to be compensated for his gas. Here is some video of him returning a few rings to some very, very happy people.
